500 Words Essay on Benefits of Exercise

Exercise, often regarded as a panacea for numerous health-related issues, has been a subject of extensive research over the years. It is a powerful tool that aids in the enhancement of both physical and mental well-being. This essay aims to explore the multifaceted benefits of exercise, ranging from improved physical health to enhanced cognitive abilities.

The first and most apparent advantage of exercise is its profound impact on physical health. Regular physical activity strengthens the cardiovascular system, reducing the risk of heart disease and stroke. Exercise aids in the regulation of blood pressure and cholesterol levels, two significant risk factors for these conditions.

In addition to cardiovascular health, exercise contributes to better respiratory health by enhancing lung capacity and efficiency. It also plays a crucial role in weight management, as it helps burn calories, preventing obesity and associated diseases like diabetes and certain types of cancer.

The benefits of exercise are not limited to physical health; they also extend to mental well-being. Regular physical activity has been shown to reduce symptoms of anxiety and depression. It stimulates the production of endorphins, often referred to as ‘feel-good’ hormones, which elevate mood and promote a sense of well-being.

Exercise also aids in stress management. Engaging in physical activity diverts the mind from stressors, providing a respite from negative thoughts. Furthermore, the accomplishment of fitness goals often boosts self-esteem and confidence.

Recent research has unveiled the cognitive benefits of regular exercise. It has been found to enhance memory and thinking skills. Exercise promotes the growth of new brain cells and improves connections between neurons, leading to better brain health. It can also slow down the cognitive decline associated with aging, thereby reducing the risk of diseases like Alzheimer’s and dementia.

Social Benefits

Exercise often serves as a social activity, providing opportunities to meet new people and strengthen relationships. Participating in group exercises or sports can foster a sense of community and belonging, which is crucial for emotional well-being. Moreover, it can also enhance teamwork and leadership skills, which are invaluable in various aspects of life.

In conclusion, the benefits of exercise are manifold, ranging from physical health improvements to mental and cognitive enhancements. It is a cost-effective and accessible method to maintain overall health and improve quality of life. As college students, integrating regular physical activity into our routine can provide us with the stamina to deal with academic pressures and equip us with skills that are beneficial in the long run. Therefore, exercise is not just about maintaining physical fitness; it is a comprehensive approach to holistic well-being.

Exercise: 7 benefits of regular physical activity.

You know exercise is good for you, but do you know how good? From boosting your mood to improving your sex life, find out how exercise can improve your life.

Want to feel better, have more energy and even add years to your life? Just exercise.

The health benefits of regular exercise and physical activity are hard to ignore. Everyone benefits from exercise, no matter their age, sex or physical ability.

Need more convincing to get moving? Check out these seven ways that exercise can lead to a happier, healthier you.

1. Exercise controls weight

Exercise can help prevent excess weight gain or help you keep off lost weight. When you take part in physical activity, you burn calories. The more intense the activity, the more calories you burn.

Regular trips to the gym are great, but don't worry if you can't find a large chunk of time to exercise every day. Any amount of activity is better than none. To gain the benefits of exercise, just get more active throughout your day. For example, take the stairs instead of the elevator or rev up your household chores. Consistency is key.

2. Exercise combats health conditions and diseases

Worried about heart disease? Hoping to prevent high blood pressure? No matter what your current weight is, being active boosts high-density lipoprotein (HDL) cholesterol, the "good" cholesterol, and it decreases unhealthy triglycerides. This one-two punch keeps your blood flowing smoothly, which lowers your risk of heart and blood vessel, called cardiovascular, diseases.

Regular exercise helps prevent or manage many health problems and concerns, including:

• Metabolic syndrome.
• High blood pressure.
• Type 2 diabetes.
• Depression.
• Many types of cancer.

It also can help improve cognitive function and helps lower the risk of death from all causes.

3. Exercise improves mood

Need an emotional lift? Or need to lower stress after a stressful day? A gym session or brisk walk can help. Physical activity stimulates many brain chemicals that may leave you feeling happier, more relaxed and less anxious.

You also may feel better about your appearance and yourself when you exercise regularly, which can boost your confidence and improve your self-esteem.

4. Exercise boosts energy

Winded by grocery shopping or household chores? Regular physical activity can improve your muscle strength and boost your endurance.

Exercise sends oxygen and nutrients to your tissues and helps your cardiovascular system work more efficiently. And when your heart and lung health improve, you have more energy to tackle daily chores.

5. Exercise promotes better sleep

Struggling to snooze? Regular physical activity can help you fall asleep faster, get better sleep and deepen your sleep. Just don't exercise too close to bedtime, or you may be too energized to go to sleep.

6. Exercise puts the spark back into your sex life

Do you feel too tired or too out of shape to enjoy physical intimacy? Regular physical activity can improve energy levels and give you more confidence about your physical appearance, which may boost your sex life.

But there's even more to it than that. Regular physical activity may enhance arousal for women. And men who exercise regularly are less likely to have problems with erectile dysfunction than are men who don't exercise.

7. Exercise can be fun — and social!

Exercise and physical activity can be fun. They give you a chance to unwind, enjoy the outdoors or simply do activities that make you happy. Physical activity also can help you connect with family or friends in a fun social setting.

So take a dance class, hit the hiking trails or join a soccer team. Find a physical activity you enjoy, and just do it. Bored? Try something new, or do something with friends or family.

Exercise to feel better and have fun

Exercise and physical activity are great ways to feel better, boost your health and have fun. For most healthy adults, the U.S. Department of Health and Human Services recommends these exercise guidelines:

Aerobic activity. Get at least 150 minutes of moderate aerobic activity. Or get at least 75 minutes of vigorous aerobic activity a week. You also can get an equal combination of moderate and vigorous activity. Aim to spread out this exercise over a few days or more in a week.

For even more health benefits, the guidelines suggest getting 300 minutes a week or more of moderate aerobic activity. Exercising this much may help with weight loss or keeping off lost weight. But even small amounts of physical activity can be helpful. Being active for short periods of time during the day can add up and have health benefits.

• Strength training. Do strength training exercises for all major muscle groups at least two times a week. One set of each exercise is enough for health and fitness benefits. Use a weight or resistance level heavy enough to tire your muscles after about 12 to 15 repetitions.

Moderate aerobic exercise includes activities such as brisk walking, biking, swimming and mowing the lawn.

Vigorous aerobic exercise includes activities such as running, swimming laps, heavy yardwork and aerobic dancing.

You can do strength training by using weight machines or free weights, your own body weight, heavy bags, or resistance bands. You also can use resistance paddles in the water or do activities such as rock climbing.

If you want to lose weight, keep off lost weight or meet specific fitness goals, you may need to exercise more.

Remember to check with a health care professional before starting a new exercise program, especially if you have any concerns about your fitness or haven't exercised for a long time. Also check with a health care professional if you have chronic health problems, such as heart disease, diabetes or arthritis.

Physical Activity Is Good for the Mind and the Body

Health and Well-Being Matter is the monthly blog of the Director of the Office of Disease Prevention and Health Promotion.

Everyone has their own way to “recharge” their sense of well-being — something that makes them feel good physically, emotionally, and spiritually even if they aren’t consciously aware of it. Personally, I know that few things can improve my day as quickly as a walk around the block or even just getting up from my desk and doing some push-ups. A hike through the woods is ideal when I can make it happen. But that’s me. It’s not simply that I enjoy these activities but also that they literally make me feel better and clear my mind.

Mental health and physical health are closely connected. No kidding — what’s good for the body is often good for the mind. Knowing what you can do physically that has this effect for you will change your day and your life.

Physical activity has many well-established mental health benefits. These are published in the Physical Activity Guidelines for Americans and include improved brain health and cognitive function (the ability to think, if you will), a reduced risk of anxiety and depression, and improved sleep and overall quality of life. Although not a cure-all, increasing physical activity directly contributes to improved mental health and better overall health and well-being.

Learning how to routinely manage stress and getting screened for depression are simply good prevention practices. Awareness is especially critical at this time of year when disruptions to healthy habits and choices can be more likely and more jarring. Shorter days and colder temperatures have a way of interrupting routines — as do the holidays, with both their joys and their stresses. When the plentiful sunshine and clear skies of temperate months give way to unpredictable weather, less daylight, and festive gatherings, it may happen unconsciously or seem natural to be distracted from being as physically active. However, that tendency is precisely why it’s so important that we are ever more mindful of our physical and emotional health — and how we can maintain both — during this time of year.

Roughly half of all people in the United States will be diagnosed with a mental health disorder at some point in their lifetime, with anxiety and anxiety disorders being the most common. Major depression, another of the most common mental health disorders, is also a leading cause of disability for middle-aged adults. Compounding all of this, mental health disorders like depression and anxiety can affect people’s ability to take part in health-promoting behaviors, including physical activity. In addition, physical health problems can contribute to mental health problems and make it harder for people to get treatment for mental health disorders.

The COVID-19 pandemic has brought the need to take care of our physical and emotional health to light even more so these past 2 years. Recently, the U.S. Surgeon General highlighted how the pandemic has exacerbated the mental health crisis in youth .

The good news is that even small amounts of physical activity can immediately reduce symptoms of anxiety in adults and older adults. Depression has also shown to be responsive to physical activity. Research suggests that increased physical activity, of any kind, can improve depression symptoms experienced by people across the lifespan. Engaging in regular physical activity has also been shown to reduce the risk of developing depression in children and adults.

Though the seasons and our life circumstances may change, our basic needs do not. Just as we shift from shorts to coats or fresh summer fruits and vegetables to heartier fall food choices, so too must we shift our seasonal approach to how we stay physically active. Some of that is simply adapting to conditions: bundling up for a walk, wearing the appropriate shoes, or playing in the snow with the kids instead of playing soccer in the grass.

Sometimes there’s a bit more creativity involved. Often this means finding ways to simplify activity or make it more accessible. For example, it may not be possible to get to the gym or even take a walk due to weather or any number of reasons. In those instances, other options include adding new types of movement — such as impromptu dance parties at home — or doing a few household chores (yes, it all counts as physical activity).

During the COVID-19 pandemic, I built a makeshift gym in my garage as an alternative to driving back and forth to the gym several miles from home. That has not only saved me time and money but also afforded me the opportunity to get 15 to 45 minutes of muscle-strengthening physical activity in at odd times of the day.

For more ideas on how to get active — on any day — or for help finding the motivation to get started, check out this Move Your Way® video .

The point to remember is that no matter the approach, the Physical Activity Guidelines recommend that adults get at least 150 minutes of moderate-intensity aerobic activity (anything that gets your heart beating faster) each week and at least 2 days per week of muscle-strengthening activity (anything that makes your muscles work harder than usual). Youth need 60 minutes or more of physical activity each day. Preschool-aged children ages 3 to 5 years need to be active throughout the day — with adult caregivers encouraging active play — to enhance growth and development. Striving toward these goals and then continuing to get physical activity, in some shape or form, contributes to better health outcomes both immediately and over the long term.

For youth, sports offer additional avenues to more physical activity and improved mental health. Youth who participate in sports may enjoy psychosocial health benefits beyond the benefits they gain from other forms of leisure-time physical activity. Psychological health benefits include higher levels of perceived competence, confidence, and self-esteem — not to mention the benefits of team building, leadership, and resilience, which are important skills to apply on the field and throughout life. Research has also shown that youth sports participants have a reduced risk of suicide and suicidal thoughts and tendencies. Additionally, team sports participation during adolescence may lead to better mental health outcomes in adulthood (e.g., less anxiety and depression) for people exposed to adverse childhood experiences. In addition to the physical and mental health benefits, sports can be just plain fun.

Physical activity’s implications for significant positive effects on mental health and social well-being are enormous, impacting every facet of life. In fact, because of this national imperative, the presidential executive order that re-established the President’s Council on Sports, Fitness & Nutrition explicitly seeks to “expand national awareness of the importance of mental health as it pertains to physical fitness and nutrition.” While physical activity is not a substitute for mental health treatment when needed and it’s not the answer to certain mental health challenges, it does play a significant role in our emotional and cognitive well-being.

No matter how we choose to be active during the holiday season — or any season — every effort to move counts toward achieving recommended physical activity goals and will have positive impacts on both the mind and the body. Along with preventing diabetes, high blood pressure, obesity, and the additional risks associated with these comorbidities, physical activity’s positive effect on mental health is yet another important reason to be active and Move Your Way .

As for me… I think it’s time for a walk. Happy and healthy holidays, everyone!

Yours in health, Paul

Physical inactivity is a modifiable risk factor (similar to dyslipidemia and hypertension) for a variety of chronic diseases, including cancer and cardiovascular disease. Exercise provides a clear health benefit, which serves in the primary and secondary prevention of these disease processes (the most important being a reduction in cardiovascular disease and premature death). The physiologic mechanisms for such a benefit occur at both a cellular and multisystem level. Prolonged periods of occupational or leisure-time sitting have adverse health effects independent of exercise performed before or after. Almost any form of physical activity (PA) is beneficial, whether part of a regular exercise program or as a series of intermittent, incidental, non-purposeful, lifestyle-embedded activity (causing non-exercise activity thermogenesis or NEAT). The health benefits of exercise appear to be dose-dependent. Physicians should recommend near daily exercise which includes at various times strength training, stretching, and aerobic activity in addition to emphasizing adjustments that allow for reduced sitting and increased activity during daily routines. Patients should understand that for optimal health, exercise is no longer optional.

Introduction

Physical inactivity is a modifiable risk factor for cardiovascular disease, obesity, depression, cancer, diabetes mellitus, hypertension, and osteoporosis. Physical exercise reduces the risk of premature death and prolongs longevity, and is an important treatment modality in the primary and secondary prevention of the above disorders [ 1 ]. For most states in this country, less than half of the population meets CDC exercise recommendations [ 2 •]. The decline in physical activity (PA) occurs both at work and in leisure time, and may have at least partially contributed to the increase in obesity over the past 30 years. Low recreational physical activities have been associated with a threefold increase for major weight gain in men and a fourfold increase in women [ 3 ]. Surveys of PA across the lifecycle show that physical exercise peaks in the middle high-school age range and begins declining through high school and into adult life. A vicious cycle of decline occurs between inactivity and loss of skeletal muscle mass which accelerates with age. With avoidance of activity requiring effort, there is increased loss of exercise capacity. This loss causes the perception of effort associated with even sub-maximal work to worsen, as the anaerobic threshold decreases. The vicious cycle contributes to further inactivity and deterioration of physical function. The only treatment that can break the cycle is exercise.

Impact of Exercise on Aging

Exercise provides powerful health benefits for quality of life, physical function, and independent living throughout the life cycle. Exercise impedes the aging process and promotes longevity. Observational studies have shown that even in the presence of disease processes such as hypertension (HTN), chronic obstructive pulmonary disease (COPD), diabetes, smoking, high body mass index (BMI), and hypercholesterolemia, increasing PA has a dose-dependent effect in decreasing relative risk of death [ 4 ]. In a study of subjects over a 13-year time period, both baseline fitness, and improvement in physical fitness through exercise and PA was associated with significant increases in longevity [ 4 ]. Functional independence with advanced age relates to the overall level of physical fitness. Physical fitness is most affected by the status of the cardiorespiratory and vascular systems, as well as muscle function [ 5 •].

Garatachea et al. provide an excellent review of the effect of exercise on the physiologic changes associated with aging [ 5 •]. Exercise exerts its positive influence on both a cellular level and at the level of organ systems. At the cellular level, exercise helps reduce genomic instability, epigenetic alteration, loss of proteostasis, dysregulated nutrient sensing, cellular senescence, and altered intracellular communication that leads to inflammation. These effects alter the way the body performs transcellular signaling in the skeletal muscle, the turning on and off of genes through epigenetics, and the manner in which the system manages reactive oxygen species [ 5 •]. On a multisystem level, the benefits of exercise include improvement in brain, cardiovascular, lung, and muscle function, favorable alterations in body composition, and advantageous changes in metabolic responses. The report concludes by suggesting that in the future, pharmaceuticals should be designed which mimic the effects of exercise on the aging process [ 5 •].

Effect of Exercise on Treatment of Disease

Robert Butler from the National Institute on Aging has said that “If exercise could be put in a bottle, it would be the strongest medicine money could buy” [ 6 ]. Exercise helps prevent common chronic diseases (primary prevention), and often plays an important role in the treatment of these disease processes (secondary prevention). Specific benefits from exercise have been seen with cardiovascular disease, stroke, diabetes mellitus, depression, cancer, obesity, and osteoporosis [ 7 , 8 ]

Cardiovascular Disease

Increased levels of PA and physical fitness have a graded effect in reducing the risk of death from cardiovascular disease. The relative risk from all cause and cardiovascular disease mortality is reduced 20–35 % by exercise and PA [ 9 ]. In an observational study, subjects in the lowest quintile of exercise had a relative risk of 3.4 in men and 4.7 in women for death compared to those in the highest quintile [ 10 ]. An increase in activity-related energy expenditure by as little as 1000 kcal or 1 metabolic equivalent (MET)-hour of exercise per week has a mortality benefit of 20 % [ 11 ]. Physically inactive women have a 52 % increase in death, a cardiovascular disease-related death that is doubled, and a cancer-related death rate that is increased by 29 % [ 11 ]. These risks on mortality from inactivity are similar to other modifiable risk factors such as HTN, hypercholesterolemia, and obesity. In randomized controlled trials (RCT)s, exercise and PA are valuable for the secondary prevention of cardiovascular disease. Whereas in the past, traditional recommendations for patients with a heart attack included rest and physical inactivity. Newer information demonstrates that exercise actually attenuates or reverses risk of cardiovascular disease [ 12 ]. The benefit of exercise is seen in cardiac rehabilitation, where increasing PA reduces the risk of premature death following a myocardial infarction [ 12 ]. Added energy expenditure of 1600 kcal/week from exercise may halt the progression of heart disease and energy expenditure of >2200 kcal/week can lead to plaque reduction [ 13 ]. The minimum training recommendation for patients following myocardial infarction is to reach 45 % of their heart rate reserve through cardiac rehabilitation [ 12 , 13 ].

Multiple mechanisms have been identified whereby exercise reduces the risk of premature death [ 4 ]. Exercise affects body composition by decreasing abdominal adiposity and improving weight control. Exercise enhances lipid profiles by reducing serum triglyceride levels, raising HDL, and reducing the LDL/HDL ratio. In addition, a recent meta-analysis showed beneficial changes in lipoprotein subclasses associated with regular exercise including a reduction in small LDL-p and an increase in large LDL-p [ 14 ]. Exercise enhances hemodynamics by decreasing blood pressure, increasing cardiac function, and improving coronary blood flow. Autonomic tone is enhanced and shear stress-mediated endothelial function is improved. Exercise reduces systemic inflammation, as evidenced by reduced C-reactive protein (CRP) levels. Improved psychological well-being in response to exercise is associated with reduced stress, anxiety, and depression [ 4 ].

PA is inversely correlated with risk of incident stroke as shown in a large nurses’ health study [ 15 ]. Habitual exercise reduces risk of stroke by 40–50 % at the highest level of PA. Change in PA is protective against stroke as evidenced by the fact that an increase of 3.5 h of exercise or PA per week is associated with a 29 % reduction in ischemic stroke [ 15 ].

Diabetes Mellitus

Exercise is valuable in both the primary and secondary prevention of diabetes mellitus. Aerobic and resistant-type exercise reduces the likelihood of developing type-2 diabetes mellitus. For each 500 kcal of energy expended per week, there is an associated 6 % reduction in the likelihood of type-2 diabetes (which may be even greater with increasing BMI) [ 16 ]. In patients already diagnosed to have diabetes mellitus, walking 2 h per week is associated with a 39–54 % reduction in all-cause mortality from diabetes mellitus, and a 34–53 % reduction in mortality related to cardiovascular disease [ 17 ]. The benefit of exercise on glycemic control appears to be greater with resistance training than aerobic exercise. A meta-analysis of exercise and PA in diabetes showed that exercise reduces hemoglobin A1C by 0.66 %, an effect similar to intensive glucose-lowering pharmacologic therapy [ 18 ]. The mechanisms by which exercise benefits diabetes relate to the fact that exercise increases glycogen synthetase and hexokinase activity [ 4 ]. Exercise reduces GLUT-4 protein and messenger RNA expression and increases muscle capillary density, which helps improve glucose delivery to the muscle [ 4 ].

Increasing PA, either occupational or at leisure, has been shown to exert a primary preventative effect on two cancers—breast and colon cancer [ 19 ]. Moderate exercise of as little as 4–5 METs (equivalent to mowing the lawn or brisk walking), is required to achieve this effect [ 20 ]. Exercise is associated with a 20–30 % reduction in the incidence of breast cancer in women, and a 30–40 % reduction in the incidence of colon cancer in both men and women [ 20 ]. In those patients already diagnosed to have one of these cancers, exercise reduces the likelihood for cancer recurrence and reduces risk from cancer death by as much as 26–40 % [ 21 ]. PA improves quality of life and overall health status in cancer patients. The mechanisms by which exercise improves risk from cancer may relate to reduced fat stores, an increase in energy expenditure offsetting a high-fat diet, activity-related changes in sex hormone levels, improvement in immune function, and reduced generation of free oxygen radicals [ 4 ].

Osteoporosis

Exercise has a valuable effect in the primary prevention of osteoporosis. Routine PA minimizes age-related bone loss. Weight-bearing exercise (especially resistance exercise) increases bone density compared to low impact non-weight-bearing exercise. Exercise prevents 1 % of bone loss per year, an effect which is greater in post-menopausal than pre-menopausal women [ 22 ]. In RCTs, exercise reduces the risk and number of falls, as well as the risk of fracture [ 22 ]. Even in men, PA reduces the risk of fracture by 62 % over the age of 21 years [ 23 ]. Exercise is also valuable in the secondary prevention of osteoporosis. RCTs in the past have shown that exercise with resistance training increases bone density in older osteoporotic women by as much as 1.4 %, while agility training alone increases bone density by 0.5 % [ 24 ]. Stretching, which was used as sham control, was shown to have no effect on the expected decrease in bone density with age [ 24 ]. In a 12-year follow up of over 60,000 post-menopausal women, risk of hip fracture was lowered 6 % for each increase of three MET-hours per week of activity (the equivalent of walking three miles in 1 h) [ 25 ]. Active women with at least 24 met-hours of exercise per week had a 55 % lower risk of hip fracture than sedentary women with no other exercise. Walking at least 4 h per week was associated with a 41 % lower risk of hip fracture than walking less than one hour per week [ 25 ].

Exercise has a valuable therapeutic effect on the treatment on multiple types of depression, including dysthymic, seasonal, bipolar, post-natal, pre-menstrual, atypical, and major depression [ 26 ]. The value in treating depression comes from an innate anti-depressive effect from exercise. Combining exercise with psychotropic medications achieves better treatment results than the same medications alone [ 26 ]. Exercise is relatively inexpensive, safe, and has minimal side effects when done correctly. Exercise may help reduce the dose of anti-depressive medications required. Subjects are less likely to relapse with an active exercise program [ 26 ].

The patients with depression who are most likely to benefit from exercise include those with age <20 or >40 years, higher education, higher baseline physical status, females, untrained subjects, and those with mild to moderate depression [ 26 ]. There are a number of aspects of exercise that get the optimal results in treating depression including programs that are structured, individually tailored to the patient, low to moderate intensity, when it is used as an adjunct to medication therapy, and exercise that is a combination of aerobic or resistive training performed 3–4 times per week [ 26 ]. The mechanism of effect from exercise on depression occurs on a systemic level as well as a direct effect on central nervous system (CNS) function. Exercise appears to increase serotonin, ACTH, endorphins, and endocannabinoids within the CNS. On a systemic level, exercise increases norepinephrine and reduces cortisol, tumor necrosis factor (TNF), and interleukin-6 [ 26 ].

In a controversial article that appeared in Time magazine in 2009, the journalist John Cloud wrote about “The Myth of Exercise” and its effect on treating obesity [ 27 ]. The article suggested that exercise was not good for weight management in obesity. The author pointed out that exercise leads to increased appetite and intake of food and causes a decrease in non-exercise energy expenditure, and therefore that exercise was a poor strategy for weight loss [ 27 ]. A number of letters to the editor of Time magazine followed the publication of this article, including letters from the American Society for Sports Medicine, arguing that facts were misrepresented and that the article gave the wrong message about the health benefits of exercise.

A recent review by Swift clarified the role of exercise in managing or preventing obesity, and suggested that Cloud’s article was in fact an accurate portrayal of the facts [ 28 ]. The key issue of Swift’s review is that exercise without caloric restriction is unlikely to succeed in weight loss [ 28 ]. Increasing PA can prevent weight gain, but it requires 150–250 min per week of moderate to vigorous exercise or 1200–2000 kcal/week expended through exercise to accomplish this feat [ 29 ]. Aerobic exercise by itself is minimally helpful in promoting weight loss, successful in loss of only 0–2 kg total [ 29 ]. Extreme high-volume aerobic exercise can achieve significant weight loss, but this is usually unsustainable by most obese patients. Moderate intensity, surprisingly, is no different than vigorous intensity in achieving weight loss, unless subjects are matched for exercise duration. Resistance training by itself has no impact on weight loss, and aerobic training combined with resistant training has no greater effect than aerobic training alone. However, adding caloric restriction to aerobic training does result in successful weight loss of 9–13 kg, and higher intensity of exercise has the potential for even greater weight loss [ 29 ]. Some obese subjects do experience weight compensation in response to exercise, defined by the circumstances where less weight is lost than expected with the amount of exercise sustained, often a factor related to an increase in caloric intake [ 28 , 30 ]. This is more likely to occur in women performing 150 % of weekly recommendations (compared to women performing only 100 % or 50 % of weekly recommendations) [ 28 , 30 ]. Even if minimal or no weight loss occurs in response to exercise, obese subjects still benefit from the increase in PA due to increased cardiorespiratory fitness, glucose control, endothelial function, improvements in hyperlipidemia, quality of life, and a reduction in future weight gain [ 28 ].

Caloric restriction is better than exercise for significant weight loss initially, and the weight loss is not necessarily enhanced significantly by adding exercise [ 28 ], although exercise training plus caloric restriction does improve body composition by increasing fat loss and decreasing loss of lean body mass [ 31 ]. The greatest value of exercise in the management of obesity occurs not in the initial weight loss, but in the situation where obese patients have lost weight successfully and now require substantial PA to maintain that weight loss [ 28 ]. Interestingly, an “energy gap” has been identified as the difference in energy expenditure before and after weight loss [ 32 ]. The energy gap is estimated to be approximately 8 kcal per day per pound of weight lost. An energy gap, for example, of 40 lbs lost would be associated with 320 kcal of energy. Sustaining this weight loss successfully would require either a continued reduction in energy consumption by 320 kcal per day, or increasing activity-associated energy expenditure by the same amount [ 32 ]. Based on the Set Point theory, both biological and environmental pressures oppose the strategy of food restriction in keeping weight off, but the same effect does not occur with increased PA [ 32 ]. Therefore, while food restriction is the key to weight loss, PA is the key to successful maintenance of the weight lost [ 32 ]. The ACSM has identified that people who successfully maintain weight loss average at least 250 min of PA per week [ 29 ].

Low Back Pain

A 2016 systematic review and meta-analysis reviewed 23 randomized controlled trials evaluating the prevention of low back pain [ 33 ]. Over 30,000 patients were involved in these studies. Ultimately, the combination of exercise (varying regimens of abdominal strengthening, core stability, cardiovascular, and isometrics) plus education regarding prevention of low back pain was found to reduce the risk of low back pain as well as sick leave related to low back pain. Exercise alone was also found to have an impact but had a more short term effect (<12 months), thought to be due to cessation of exercise following the intervention. Other interventions, including back belts, insoles, and education alone were not found to have any impact [ 33 ].

Not All Exercise is Created Equal

Physical activity versus physical fitness.

The lay public tends to use the terms PA and physical fitness interchangeably, but subtle differences between the two exist. Physical fitness is a physiologic state of being with regard to daily living and/or sports performance [ 4 ]. Physical fitness is comprised of cardiovascular, musculoskeletal, body composition, and metabolic components [ 4 ]. Physical fitness is similar to PA, but is more predictive of health outcomes. For example, a high-fit versus a low-fit person is estimated to have a 50 % lower mortality [ 34 ]. Physical fitness, therefore, becomes a better measure of PA than self-reporting. From a public health standpoint, however, it is better and more productive to encourage the public to be physically active and not push the need to be physically fit. Eventually, increased activity should lead to physical fitness.

In the past, guidelines for optimal health seemed to have had a singular focus on aerobic fitness. But a new paradigm shift has occurred with the addition of the concept of musculoskeletal fitness [ 4 ]. In other words, health status can improve due to increased PA in the absence of changes in aerobic fitness. Regular PA can decrease risk factors from chronic disease and disability without changing cardiac output or oxidative potential, especially in the elderly [ 4 ]. The shift has been to focus on the health benefits of musculoskeletal fitness, which may be a critical factor in the functional threshold for dependence with the aging population. Loss of muscular fitness can result in loss of capacity for daily living, and a cycle of decline can ensue [ 4 ]. Improvement in musculoskeletal function can delay the onset of disability, dependence, and chronic disease [ 35 ]. Musculoskeletal fitness is associated with fewer functional limitations and a reduced incidence of cardiovascular disease, diabetes, degenerative joint disease, and coronary artery disease [ 35 ]. Therefore, resistance training that works all the major muscle groups (including legs, hips, back, abdomen, chest, shoulders, and arms) and flexibility exercise, which are necessary to achieve musculoskeletal fitness, are recommended to be done at least twice weekly, to complement aerobic fitness and optimize overall health status.

Adverse Health Risk from Sitting

In an effort to delineate those factors which contribute to the obesity epidemic, researchers are increasingly focused on the adverse health risk from prolonged sitting [ 36 •]. A newly recognized occupational hazard has evolved because of workers needing to sit at a computer screen throughout the workday. Each mean hour of sitting after a total mean of 7 h per day is associated with a 5 % increase in premature death [ 36 •]. More time sitting at work has been shown to correlate with more sitting in leisure time. Prolonged sitting while watching TV at home, for example, has adverse effects on mental health, well-being, and muscle strength. Long sedentary hours have been linked to a twofold increase in diabetes, a twofold increase in cardiovascular disease, a 13 % increase in the incidence of cancer, and a 17 % increase in mortality related to cancer [ 36 •]. It is estimated that the average worker in the USA and England spends 60–70 % of waking hours in a sedentary sitting position. The effect of sitting has been likened to the transmission of a car. Sitting for such a prolonged period is like putting a car in reverse, causing one’s overall health status to go in the wrong direction [ 36 •]. Approximately 20–30 % of the time is spent in light intensity activity, described as postural changes, standing and movement, or ambulation. For less than 5–10 % of waking hours, individuals spend in moderate to vigorous PA. The adverse effect of sitting on health status is independent of the exercise or PA done before or after [ 36 •]. In other words, no amount of PA later can overcome the negative health effects of prolonged sitting.

Changes in the workplace environment may be the key issue to minimizing the negative effects of prolonged sitting. Particularly, in the UK, recommendations and guidelines have been developed to avoid this health hazard [ 36 •]. Workers are encouraged to accumulate up to 2 h per day at work standing or performing light walking, with the goal to progress ultimately to 4 h per day. Workers should interrupt seat-based work with standing-based work. However, workers should avoid both prolonged periods of standing as well as prolonged periods of sitting. Adaptation of these guidelines may lead to musculoskeletal complaints and fatigue, which should be monitored by managers in the workplace. Such health promotion strategies should eventually extend from the workplace to the leisure time [ 36 •].

Non-Exercise Activity Thermogenesis

Non-exercise activity thermogenesis (NEAT) has been described as unstructured PA, energy expended unrelated to sleeping, eating, or sports exercise. NEAT is energy expended outside of purposeful exercise [ 37 ]. Surprisingly, this incidental, non-purposeful lifestyle-embedded PA can have tremendous health benefits. Three components of NEAT include body posture, ambulation, and all other movements (the most important of which may be fidgeting) [ 38 ]. Researchers involved in the study of obesity are finding that in some cases what delineates the lean subject from an obese one is a difference in NEAT, not exercise-associated activity thermogenesis [ 38 ]. Early experiments which helped identify NEAT came from studies where energy requirements were measured and all subjects were placed on a diet of 1000 cal over requirements [ 39 ]. Subjects were then videotaped, and in a blinded fashion designated as fidgeters or non-fidgeters. At the end of the trial, those patients who were designated as fidgeters failed to gain weight, while those identified to be non-fidgeters sustained significant weight gain. The increase in kilocalories of energy expenditure attributed to NEAT was inversely proportional to fat gain in pounds [ 39 ]. NEAT ranges from 15 % of total energy expenditure (TEE) in sedentary subjects to as much as 50 % of TEE in fidgeting physically active people [ 39 ]. Fidgeting has been shown in twin studies to be genetic, with an estimated >62 % heritability [ 40 ]. Simply standing or lightly ambulating can increase energy expenditure by an average of 350 kcal/day (range 269–477 kcal/day) [ 37 ]. NEAT tends to be greater in men than women, in obese subjects rather than lean, and in those with more education than those with less [ 38 , 39 ]. NEAT tends to be seasonal and overall, declines with age [ 39 ]. The concept of an energy gap is pertinent to NEAT. An average citizen in the USA has been shown to gain 1–2 lbs each year through their adult life. An energy gap of 100 kcal additional energy consumed each day would account for this weight gain [ 41 ]. NEAT can be an important contributor to TEE, such that increases in NEAT of as little as 100–150 kcal of activity per day could prevent such weight gain (by offsetting the energy gap) in the vast majority of people [ 41 ]. Recommendations now suggest that if you were not lucky enough to inherit fidgeting, you should “act like a fidgeter,” standing often, getting up from sitting, pacing, parking at the back of a parking lot, and taking stairs instead of elevators [ 40 ].

Continuous Versus Interval Exercise

Long bouts of continuous exercise as a strategy for weight loss or weight maintenance can be a contentious and challenging recommendation for the general public. Longer duration, continuous exercise may be difficult and not particularly enjoyable for patients and may not fit as well with work or home schedules. Research now has shown that interval exercise, which involves alternating short bouts of high-intensity exercise with lower-intensity exercise that allows for partial recovery, can match the health benefits of continuous exercise [ 42 ]. Studies in patients with class-1 obesity (BMI 30–34.9 kg/m 2 ), walking at a moderate level of intensity, randomized to two 15-min intervals of walking versus one 30-min interval, showed essentially the same improvements in overall health status [ 42 ]. Both intermittent and continuous exercise resulted in improvement of maximum oxygen consumption, body composition, and lipid profiles. In some categories, interval exercise even exceeded the benefit seen with continuous exercise (such as VLDL levels and percent fat lost) [ 42 ]. The value of these findings for intermittent exercise stems from three factors: there is less attrition with recommendations for interval exercise, time constraints, and short periods of interval exercising may allow for greater intensity of PA [ 42 ]. An additional study involving 28 sedentary overweight or obese men compared five 45- to 60-min sessions of continuous moderate intensity cycling per week for 6 weeks with three 20-min sessions of high-intensity interval exercise per week (for a total of 60 min) for 6 weeks. Similar improvements in cardio-metabolic risk factors including improved insulin sensitivity, cardiovascular fitness, and a reduction in blood lipids and body fat percentage were observed in the groups [ 43 ]. While cardiovascular fitness was improved to a greater extent in the continuous exercise group, this study, along with numerous other studies of interval exercise showing similar outcomes in different populations, are encouraging in that they show many of the same improvements in overall health with a substantially reduced time commitment [ 43 ]. This is especially relevant as lack of time is cited as the most common reason for not exercising by many. In addition, interval exercise can be easily adapted to an individual’s starting fitness level by adjusting either the duration or intensity (or both) of the high-intensity component of exercise. This may be especially beneficial for sedentary overweight or obese individuals who are new to exercise. In light of both the potential health and time saving benefits, interval exercise training appears to be an appealing and worthwhile exercise option in addition to, or instead of, continuous exercise. The good news for public health is that short walks on a subject’s lunch break or brief periods of activity before and after work all count, and the sum of their duration may have similar benefits to a single continuous interval of exercise of the same duration.

Success of Pedometers

The use of pedometers to increase PA was generated years ago in Japanese walking clubs. The rationalization for the pedometer was that the average stride was estimated to be 2.5 ft. Therefore, 2000 steps should approximately equal a mile, 10,000 equaling about 5 miles [ 44 ]. Based on this rationalization, PA can be classified as sedentary (<5000 steps per day), low active (5000 to 7500 steps), somewhat active (7500 to 10,000 steps), and active (>10,000 steps per day). Highly active physical exercise is associated with >12,500 steps per day [ 44 ]. This is an arbitrary categorization, however, and 10,000 steps per day may be too little for children or too much for the elderly. Weight loss using a pedometer without caloric restriction is associated with minimal to modest weight loss of <2 kg [ 44 ]. Health benefits associated with use of the pedometer may be limited to a reduction in blood pressure, with not much change in cholesterol, triglycerides, or fasting glucose [ 44 ].

Exercise in the Intensive Care Unit

Exercise is becoming increasingly important in one of the least expected circumstances, that of a critically ill patient in the intensive care unit (ICU). Researchers have found that exercising muscle increases the uptake of amino acid fuel and promotes greater protein synthesis [ 45 , 46 ]. Patients in the ICU on a ventilator in some centers are gotten out of bed and encouraged to walk with assistance in the hallway. Other centers have used a pedaling device, some of which can even be adapted for passive activity in a patient who is otherwise sedated and minimally responsive. Exercise in the critical care setting helps maintain muscular strength, reduces the risk for long-term neuromuscular weakness, shortens rehabilitation, and is more likely to result in the patient being discharged to their home [ 45 , 46 ].

Recommendations for Public Health

Similar to the Food Guide Pyramid designed by the USDA, an activity pyramid has been created to guide the public in strategies to increase flexibility, muscular strength, and aerobic capacity ( www.wellspan.org/media/3648/activitypyramid-2009.pdf ). Every day, subjects are encouraged to increase activity in leisure and at work. Three to five times per week, aerobic activity should occur, accumulating 150 min each week ( www.wellspan.org/media/3648/activitypyramid-2009.pdf ). Two to three times per week, muscular activity focusing on flexibility and strength training should be scheduled. Sitting more than 30 min at a time, watching TV, or staring at a computer screen should be minimized or reduced as much as possible ( www.wellspan.org/media/3648/activitypyramid-2009.pdf ).

Guidelines differentiate between moderate and vigorous intensity of PA. Moderate intensity is defined by a 3–5 MET level of effort, and includes activities that cause some increase in breathing and heart rate (such as walking 3–4 miles per hour, bicycling on level ground, light swimming, gardening, or mowing a lawn) [ 4 ]. Vigorous intensity is defined by ≥6 METs, and is exemplified by activities causing large increases in breathing, heart rate, and sweating. Such activities of vigorous intensity would include jogging or running at faster than a 10 min mile, aerobic dancing, competitive sports, heavy yard or construction work, brisk swimming, or fast bicycling [ 4 ].

The amount of PA needed to optimize health is not clear. The particular dose of exercise required to achieve benefits with regard to a particular disease process is difficult to ascertain. For cardiovascular disease, the intensity of PA is inversely and linearly associated with increased mortality, with the biggest effect seen as a reduction of premature death [ 47 ]. PA of >2000 kcal per week extends life by 1–2 years by age 80 [ 47 ]. An average energy expenditure of 1000 kcal per week is associated with a 20–30 % decrease in all-cause mortality. Beginning at a minimum of 1000 kcal per week, increasing benefits are seen with increasing energy expenditure, suggesting a dose-response gradient to the effect of exercise on cardiovascular health [ 47 ]. For diabetes mellitus, there is decreased risk from this disease process with PA of >5.5 METs for at least 40 min per week [ 48 ]. Walking 2 h per week decreases the risk of premature death from diabetes [ 48 ]. Moderate exercise defined by a >4.5 METs for 30–60 min per day reduces both the risk of colon cancer and breast cancer [ 19 ]. For women in particular, >7 h per week of moderate exercise has been shown to be successful in reducing risk of breast cancer (TI01). For osteoporosis, the dose-response gradient is less clear, with recommendations simply emphasizing that osteogenic adaptation is load-dependent and site-specific [ 4 ]. The Center for Disease Control (CDC), the American College of Sports Medicine, and the Healthy People 2010 recommendations provide guidelines for aerobic activity for public health purposes [ 49 ]. Adults should engage in PA of moderate intensity for at least 150 min per week or engage in PA of vigorous intensity for at least 75 min per week. Bouts of exercise may be broken up into smaller increments lasting at least 10 min [ 49 ].

Should Anyone Not be Exercising?

Jim Fixx was a celebrity journalist who helped contribute to the running craze seen in the 1980s in the USA. His sudden death from cardiovascular disease, while jogging, raised questions as to the need for medical evaluation prior to engaging in a program of increasing PA. Moderately strenuous PA may trigger ischemic events, particularly among sedentary people. There is an increased incidence of primary heart attack in high-intensity exercise. In competitive athletes, 80 % of deaths are caused by coronary artery disease. Some subjects do need to have their health risks assessed prior to engaging in an aggressive program.

The degree to which a person is evaluated prior to exercise depends on the presence or absence of cardiovascular disease risk factors and whether the exercise will be moderate or vigorous in intensity [ 50 ]. Subjects at low risk would be those who are young in age (<45 years for male, <55 years for female), are asymptomatic, and have ≤1 cardiovascular risk disease factors. These patients do not need a medical evaluation or stress test for moderate or even vigorous exercise. Subjects at moderate risk are older (men >45 years, women >55 years), or have ≥2 risk factors for cardiovascular disease. For moderate exercise, no medical evaluation may be needed, but these subjects should undergo a stress test. If exercise of vigorous intensity is planned, both a medical evaluation and a stress test should be performed. For those patients at high risk, however, defined by ≥1 sign or symptom of cardiovascular, pulmonary, or metabolic disease, both a full medical evaluation and stress test should be performed before any program is undertaken [ 50 ].

Specifically, those subjects who should not be exercising are those experiencing an acute myocardial infarction, subjects with unstable angina, systolic blood pressure >180, diastolic pressure >110 ml/Hg, uncontrolled diabetes mellitus, poorly controlled congestive heart failure, or thrombophlebitis [ 50 ].

While formal studies have shown that physician counseling is time-intensive and only minimally effective in changing behavior, physicians should no longer avoid the subject of recommendations for exercise as part of the healthcare they deliver to their patients. Physicians can begin by suggesting lifestyle changes such as climbing stairs at work, parking further away from the door on errands, walking regularly, and doing chores at home and in the yard. Clinicians should write on a prescription pad for the patient, specifying the type of exercise, duration, frequency, and intensity. The physician upon discharge from an office visit should determine plans for support and follow up to encourage success, manage obstacles, and prevent relapses. Clinicians should encourage their outpatients to involve community services such as physical therapy, mall-walking programs, school tracks, safe neighborhoods, the YMCA, and walk-a-thon’s.

Physicians should counsel that exercise is not an option. The exercise does not have to be continuous to be effective, and any physical activity counts. Patients should sit less, stand more, and plan their exercise activity at the beginning of each week. Subjects should be encouraged to find activities which they enjoy and involve others to maintain compliance. As Edward Stanley, the Earl of Derby in 1873 said, “Those who think they have not time for bodily exercise will sooner or later have to find time for illness” [ 51 ].

In addition to the apparent physical health benefits, physical activity also affects mental health positively. Physically inactive individuals have been reported to have higher rates of morbidity and healthcare expenditures. Commonly, exercise therapy is recommended to combat these challenges and preserve mental wellness. According to empirical investigations, physical activity is positively associated with certain mental health traits. In nonclinical investigations, the most significant effects of physical exercise have been on self-concept and body image. An attempt to review the current understanding of the physiological and psychological mechanisms by which exercise improves mental health is presented in this review article. Regular physical activity improves the functioning of the hypothalamus-pituitary-adrenal axis. Depression and anxiety appear to be influenced by physical exercise, but to a smaller extent in the population than in clinical patients. Numerous hypotheses attempt to explain the connection between physical fitness and mental wellness. Physical activity was shown to help with sleep and improve various psychiatric disorders. Exercise in general is associated with a better mood and improved quality of life. Physical exercise and yoga may help in the management of cravings for substances, especially in people who may not have access to other forms of therapy. Evidence suggests that increased physical activity can help attenuate some psychotic symptoms and treat medical comorbidities that accompany psychotic disorders. The dearth of literature in the Indian context also indicated that more research was needed to evaluate and implement interventions for physical activity tailored to the Indian context.

Introduction and background

Physical activity has its origins in ancient history. It is thought that the Indus Valley civilization created the foundation of modern yoga in approximately 3000 B.C. during the early Bronze Age [ 1 ]. The beneficial role of physical activity in healthy living and preventing and managing health disorders is well documented in the literature. Physical activity provides various significant health benefits. Mechanical stress and repeated exposure to gravitational forces created by frequent physical exercise increase a variety of characteristics, including physical strength, endurance, bone mineral density, and neuromusculoskeletal fitness, all of which contribute to a functional and independent existence. Exercise, defined as planned, systematic, and repetitive physical activity, enhances athletic performance by improving body composition, fitness, and motor abilities [ 2 ]. The function of physical activity in preventing a wide range of chronic illnesses and premature mortality has been extensively examined and studied. Adequate evidence links medical conditions such as cardiovascular disease and individual lifestyle behaviours, particularly exercise [ 3 ]. Regular exercise lowered the incidence of cardiometabolic illness, breast and colon cancer, and osteoporosis [ 4 ]. In addition to improving the quality of life for those with nonpsychiatric diseases such as peripheral artery occlusive disease and fibromyalgia, regular physical activity may help alleviate the discomforts of these particular diseases [ 5 ]. Exercise also helps with various substance use disorders, such as reducing or quitting smoking. As physical exercise strongly impacts health, worldwide standards prescribe a weekly allowance of "150 minutes" of modest to vigorous physical exercise in clinical and non-clinical populations [ 6 ]. When these recommendations are followed, many chronic diseases can be reduced by 20%-30%. Furthermore, thorough evaluations of global studies have discovered that a small amount of physical exercise is sufficient to provide health benefits [ 7 ].

Methodology

In this review article, a current understanding of the underlying physiological and psychological processes during exercise or physical activity that are implicated in improving mental health is presented. Search terms like "exercise" or "physical activity" and "mental health", "exercise" or "physical activity" and "depression", "exercise" or "physical activity" and "stress", "exercise" or "physical activity" and "anxiety", "exercise" or "physical activity" and "psychosis," "exercise" or "physical activity" and "addiction" were used as search terms in PubMed, Google Scholar, and Medline. An overwhelming majority of references come from works published within the past decade.

The impact of physical health on mental health

There is an increasing amount of evidence documenting the beneficial impacts of physical activity on mental health, with studies examining the effects of both brief bouts of exercise and more extended periods of activity. Systematic evaluations have indicated better outcomes for mental diseases with physical activity. Numerous psychological effects, such as self-esteem, cognitive function, mood, depression, and quality of life, have been studied [ 8 ]. According to general results, exercise enhances mood and self-esteem while decreasing stress tendencies, a factor known to aggravate mental and physical diseases [ 9 ]. Studies show that people who exercise regularly have a better frame of mind. However, it should be highlighted that a consistent link between mood enhancement and exercise in healthy individuals has not been established.

Additionally, human beings produce more of these two neurochemicals when they engage in physical activity. Human bodies manufacture opioids and endocannabinoids that are linked to pleasure, anxiolytic effects, sleepiness, and reduced pain sensitivity [ 10 ]. It has been shown that exercise can improve attention, focus, memory, cognition, language fluency, and decision-making for up to two hours [ 11 ]. Researchers state that regular physical activity improves the functioning of the hypothalamus-pituitary-adrenal (HPA) axis, lowering cortisol secretion and restoring the balance of leptin and ghrelin (Figure ​ (Figure1) 1 ) [ 12 ].

Regular exercise has immunomodulatory effects such as optimising catecholamine, lowering cortisol levels, and lowering systemic inflammation. Physical activity has been shown to increase plasma brain-derived neurotrophic factor (BDNF), which is thought to reduce amyloid-beta toxicity linked to Alzheimer's disease progression [ 13 ].

Although no causal correlations have been proven, methodologically sound research has discovered a related improvement in mentally and physically ill populations. These findings are based on research and studies conducted all across the globe, particularly in the Western Hemisphere. In order to address a widespread health problem in India, it is useful to do a literature review that draws on research conducted in a variety of settings. In addition, the prevalence of these mental illnesses and the benefits of exercise as a complementary therapy might be made clear by a meta-analysis of research undertaken in India [ 14 ].

This review also analysed published literature from India to understand the effects of exercise on mental health and the implications for disease management and treatment in the Indian context. Results from Indian studies were consistent with those found in global meta-analyses. The Indian government has made public data on interventions, such as the effects of different amounts of physical exercise. Exercising and yoga have been shown to be effective adjunct therapies for a variety of mental health conditions [ 12 ]. Though yoga may not require a lot of effort to perform, other aspects of the program, such as breathing or relaxation exercises, may have an impact on a practitioner's mental health at the same time. Due to its cultural significance as a common physical practice among Indians and its low to moderate activity level, yoga would be an appropriate activity for this assessment [ 15 ].

Yoga as an adjunctive treatment 

Although yoga is a centuries-old Hindu practice, its possible therapeutic effects have recently been studied in the West. Mind-body approaches have been the subject of a lot of studies, and some of the findings suggest they may aid with mental health issues on the neurosis spectrum. As defined by the National Center for Complementary and Alternative Medicine, "mind-body interventions" aim to increase the mind's potential to alter bodily functions [ 16 ]. Due to its beneficial effects on the mind-body connection, yoga is used as a treatment for a wide range of conditions. Possible therapeutic benefits of yoga include the activation of antagonistic neuromuscular systems, stimulation of the limbic system, and a reduction in sympathetic tone.

Anxiety and depression sufferers might benefit from practising yoga. Yoga is generally safe for most people and seldom causes unintended negative consequences. Adding yoga to traditional treatment for mental health issues may be beneficial. Many of the studies on yoga included meditation as an integral part of their methodology. Meditation and other forms of focused mental practice may set off a physiological reaction known as the relaxation response. Functional imaging has been used to implicate certain regions of the brain that show activity during meditation. According to a wealth of anatomical and neurochemical evidence, meditation has been shown to have far-reaching physiological effects, including changes in attention and autonomic nervous system modulation [ 17 ]. Left anterior brain activity, which is associated with happiness, was shown to rise considerably during meditation. There's also some evidence that meditation might worsen psychosis by elevating dopamine levels [ 18 - 20 ]. We do not yet know enough about the possible downsides of meditation for patients with mental illness, since this research lacks randomised controlled trials.

Physical activity and schizophrenia

Schizophrenia is a debilitating mental disorder that often manifests in one's early years of productive life (late second decade). Remission of this disorder occurs in just a small fraction of cases. More than 60% will have relapses, and they might occur with or without noticeable deficits. Apart from delusions, hallucinations, and formal thought disorders, many patients exhibit cognitive deficits that emerge in the early stages of the disease and do not respond adequately to therapy [ 21 ].

Treatment for schizophrenia is challenging to master. Extrapyramidal side effects are a problem with first-generation antipsychotic drugs. Obesity and dyslipidemia have been related to second-generation drugs, which may cause or exacerbate these conditions. The majority of patients do not achieve complete remission, and many do not even experience satisfactory symptom relief. Even though certain antipsychotic medications may alleviate or even exacerbate negative and cognitive symptoms, these responses are far less common. This means that patients may benefit from cognitive rehabilitation. Because of their illness or a negative reaction to their medicine, they may also have depressive symptoms. This would make their condition even more disabling. Many patients also deal with clinical and emotional complications. Tardive extrapyramidal illnesses, metabolic syndromes, defect states, and attempted suicide are all in this category. Patient compliance with treatment plans is often poor. The caregivers take on a lot of stress and often get exhausted as a result.

Evidence suggests that increased physical activity can aid in attenuating some psychotic symptoms and treating medical comorbidities that accompany psychotic disorders, particularly those subject to the metabolic adverse effects of antipsychotics. Physically inactive people with mental disorders have increased morbidity and healthcare costs. Exercise solutions are commonly recommended to counteract these difficulties and maintain mental and physical wellness [ 22 ].

The failure of current medications to effectively treat schizophrenia and the lack of improvement in cognitive or negative symptoms with just medication is an argument in favour of utilising yoga as a complementary therapy for schizophrenia. Even without concomitant medication therapy, co-occurring psychosis and obesity, or metabolic syndrome, are possible. The endocrine and reproductive systems of drug abusers undergo subtle alterations. Numerous studies have shown that yoga may improve endocrine function, leading to improvements in weight management, cognitive performance, and menstrual regularity, among other benefits. In this context, the role of yoga in the treatment of schizophrenia has been conceptualized. However, yoga has only been studied for its potential efficacy as a therapy in a tiny number of studies. There might be several reasons for this. To begin with, many yoga academies frown against the practice being adapted into a medical modality. The second misconception is that people with schizophrenia cannot benefit from the mental and physical aspects of yoga practised in the ways that are recommended. Third, scientists may be hesitant to recommend yoga to these patients because of their lack of knowledge and treatment compliance.

In a randomised controlled experiment with a yoga group (n = 21) and an exercise group (n = 20), the yoga group exhibited a statistically significant reduction in negative symptoms [ 2 ]. In accordance with the most recent recommendations of the National Institute for Health and Care Excellence (NICE), the above research provides substantial evidence for the use of yoga in the treatment of schizophrenia. According to a meta-analysis of 17 distinct studies [ 23 ] on the subject, frequent physical activity reduces the negative symptoms associated with schizophrenia considerably.

Physical activity and alcohol dependence syndrome

Substance abuse, namely alcohol abuse, may have devastating effects on a person's mental and physical health. Tolerance and an inability to control drinking are some hallmarks of alcoholism. Research shows that physical activity is an effective supplement in the fight against alcohol use disorder. In addition to perhaps acting centrally on the neurotransmitter systems, physical exercise may mitigate the deleterious health consequences of drinking. Evidence suggests that persons with alcohol use disorder are not physically active and have low cardiorespiratory fitness. A wide number of medical comorbidities, like diabetes mellitus, hypertension, and other cardiovascular illnesses, occur with alcohol use disorders. Physical exercise may be highly useful in aiding the management of these comorbidities [ 24 ].

Physical exercise and yoga may help in the management of cravings for substances when other forms of therapy, such as counselling or medication for craving management are not feasible or acceptable. Physical exercise has been shown to have beneficial effects on mental health, relieve stress, and provide an enjoyable replacement for the substance. However, the patient must take an active role in physical activity-based therapies rather than passively accept the process as it is, which is in stark contrast to the approach used by conventional medicine. Since most substance use patients lack motivation and commitment to change, it is recommended that physical activity-based therapies be supplemented with therapies focusing on motivation to change to maximise therapeutic outcomes.

One hundred seventeen persons with alcohol use disorder participated in a single-arm, exploratory trial that involved a 12-minute fitness test using a cycle ergometer as an intervention. Statistically, significantly fewer cravings were experienced by 40% [ 24 ]. Exercise programmes were found to significantly reduce alcohol intake and binge drinking in people with alcohol use disorder in a meta-analysis and comprehensive review of the effects of such therapies [ 25 ].

Physical activity and sleep

Despite widespread agreement that they should prioritise their health by making time for exercise and sufficient sleep, many individuals fail to do so. Sleep deprivation has negative impacts on immune system function, mood, glucose metabolism, and cognitive ability. Slumber is a glycogenetic process that replenishes glucose storage in neurons, in contrast to the waking state, which is organised for the recurrent breakdown of glycogen. Considering these findings, it seems that sleep has endocrine effects on the brain that are unrelated to the hormonal control of metabolism and waste clearance at the cellular level. Several factors have been proposed as potential triggers for this chain reaction: changes in core body temperature, cytokine concentrations, energy expenditure and metabolic rate, central nervous system fatigue, mood, and anxiety symptoms, heart rate and heart rate variability, growth hormone and brain-derived neurotrophic factor secretion, fitness level, and body composition [ 26 ].

After 12 weeks of fitness training, one study indicated that both the quantity and quality of sleep in adolescents improved. Studies using polysomnography indicated that regular exercise lowered NREM stage N1 (very light sleep) and raised REM sleep (and REM sleep continuity and performance) [ 22 ]. As people age, both short- and long-term activities have increasingly deleterious effects on sleep. In general, both short- and long-term exercise were found to have a favourable effect on sleep quality; however, the degree of this benefit varied substantially among different sleep components. On measures of sleep quality, including total sleep time, slow-wave sleep, sleep onset latency, and REM sleep reduction, acute exercise had no effect. But both moderate and strenuous exercise has been shown to increase sleep quality [ 27 ]. According to a meta-analysis of randomised controlled trials, exercise has shown a statistically significant effect on sleep quality in adults with mental illness [ 28 ]. These findings emphasise the importance that exercise plays in improving outcomes for people suffering from mental illnesses.

Physical activity in depressive and anxiety disorders

Depression is the leading cause of disability worldwide and is a major contributor to the global burden of disease, as per the World Health Organization. However, only 10%-25% of depressed people actually seek therapy, maybe due to a lack of money, a lack of trained doctors, or the stigma associated with depression [ 29 ]. For those with less severe forms of mental illness, such as depression and anxiety, regular physical exercise may be a crucial part of their treatment and management. Exercise and physical activity might improve depressive symptoms in a way that is comparable to, if not more effective than, traditional antidepressants. However, research connecting exercise to a decreased risk of depression has not been analysed in depth [ 30 ]. Endorphins, like opiates, are opioid polypeptide compounds produced by the hypothalamus-pituitary system in vertebrates in response to extreme physical exertion, emotional arousal, or physical pain. The opioid system may mediate analgesia, social bonding, and depression due to the link between b-endorphins and depressive symptoms (Figure ​ (Figure2 2 ).

The "endorphin hypothesis" states that physical activity causes the brain to produce more endogenous opioid peptides, which reduce pain and boost mood. The latter reduces feelings of worry and hopelessness. A recent study that demonstrated endorphins favourably improved mood during exercise, and provided support for these theories suggested that further research into the endorphin theory is required [ 31 ].

Physical activity and exercise have been shown to improve depressive symptoms and overall mood in people of all ages. Exercise has been implicated in lowering depressive and anxious symptoms in children and adolescents as well [ 32 ]. Pooled research worldwide has revealed that physical exercise is more effective than a control group and is a viable remedy for depression [ 33 ]. Most forms of yoga that start with a focus on breathing exercises, self-awareness, and relaxation techniques have a positive effect on depression and well-being [ 34 ]. Despite claims that exercise boosts mood, the optimal kind or amount of exercise required to have this effect remains unclear and seems to depend on a number of factors [ 35 ].

Exercise as a therapy for unipolar depression was studied in a meta-analysis of 23 randomised controlled trials involving 977 subjects. The effect of exercise on depression was small and not statistically significant at follow-up, although it was moderate in the initial setting. When compared to no intervention, the effect size of exercise was large and significant, and when compared to normal care, it was moderate but still noteworthy [ 36 ]. A systematic evaluation of randomised controlled trials evaluating exercise therapies for anxiety disorders indicated that exercise appeared useful as an adjuvant treatment for anxiety disorders but was less effective than antidepressant treatment [ 37 ].

Conclusions

The effects of exercise on mental health have been shown to be beneficial. Among persons with schizophrenia, yoga was shown to have more positive effects with exercise when compared with no intervention. Consistent physical activity may also improve sleep quality significantly. Patients with alcohol dependence syndrome benefit from a combination of medical therapy and regular exercise since it motivates them to battle addiction by decreasing the craving. There is also adequate evidence to suggest that physical exercise improves depressive and anxiety symptoms. Translating the evidence of the benefits of physical exercise on mental health into clinical practice is of paramount importance. Future implications of this include developing a structured exercise therapy and training professionals to deliver it. The dearth of literature in the Indian context also indicates that more research is required to evaluate and implement interventions involving physical activity that is tailored to the Indian context.

Women may realize health benefits of regular exercise more than men, study says

NEW YORK, Feb. 19 (UPI) -- Women who exercise regularly have a much lower risk of premature death or a fatal cardiovascular event than men who work out the same length of time, a new study indicates.

The findings, supported by the National Institutes of Health, were published Monday in the Journal of the American College of Cardiology. The results are based on a data analysis of more than 400,000 U.S. adults ages 27 to 61.

Over two decades, women who exercised regularly were 24% less likely than those who didn't work out to experience death from any cause, while men were 15% less likely. Women also had a 36% reduced risk for a fatal heart attack, stroke or other cardiovascular event, while men had a 14% decreased risk.

Researchers noted that women on average tend to exercise less than men, and said that hopefully, these findings will motivate more women to incorporate greater movement into their lives.

"The good news is that for women -- they do seem to get more out of every minute of exercise when compared to men," the study's co-lead author, Dr. Martha Gulati, told UPI via email.

But telling a never-exerciser to strive toward about 30 minutes a day "can sound overwhelming and impossible, so they will resign and not even start any activity," said Gulati, director of preventive cardiology in the Smidt Heart Institute at Cedars-Sinai in Los Angeles.

She suggested that men and women begin with five minutes a day and then increase the time.

The link for greater reduced risks for mortality among women compared to men held true for all forms of exercise -- moderate aerobic activity, such as brisk walking; vigorous exercise, such as taking a spinning class or jumping rope; and strength training, which could include body-weight exercises.

Yet, for moderate aerobic physical activity, the decreased risk for death plateaued for both men and women at 300 minutes, or five hours, per week. At this degree of activity, women and men lowered their risk of an early death by 24% and 18%, respectively.

Similar trends existed with 110 minutes of weekly vigorous aerobic exercise, which correlated with a 24% reduced risk of death for women and a 19% decreased risk for men.

Women also reaped the same rewards as men, but in less time. With moderate aerobic exercise, they reached the 18% reduced risk point in half as much time as men: 140 minutes, or under 2.5 hours, per week, compared to 300 minutes for men.

For vigorous aerobic exercise, women met the 19% reduced risk mark with only 57 minutes a week, compared to 110 minutes for men.

This benefit extended to weekly strength training exercises. Women and men who engaged in strength-based exercises saw a 19% and 11% decreased risk for death, respectively, compared to those who did not take part in these exercises.

Women who pursued strength training had an even more substantially lower risk of cardiovascular-related deaths -- a 30% reduced risk, compared to 11% for men.

Despite all these benefits, only 33% of women and 43% of men in the study met the standard for weekly aerobic exercise, while 20% of women and 28% of men completed a weekly strength training session.

Multiple factors, including variations in anatomy and physiology, may explain the differences in outcomes between the sexes, the researchers said.

For example, men often have greater lung capacity, larger hearts, more lean-body mass and a more significant proportion of fast-twitch muscle fibers compared to women. As a result, women may use added respiratory, metabolic and strength demands to do the same movement, and in turn achieve more health benefits.

"It is important to study women and to look for sex differences," Gulati said. "Women are not simply small men. They are physiologically different."

Adults should aim for at least 2 1/2 to five hours of moderate-intensity exercise or 1 1/4 to 2 1/2 hours of vigorous exercise weekly, or a combination of both, and participate in strength-based activities two or more days per week, according to The Physical Activity Guidelines for Americans .

The research was partially supported by grants from the National Heart, Lung, and Blood Institute.

"This study emphasizes that there is no singular approach for exercise," Eric J. Shiroma, a program director in the institute's Clinical Applications and Prevention branch, said in a news release.

"A person's physical activity needs and goals may change based on their age, health status and schedule, but the value of any type of exercise is irrefutable," Shiroma said.

Exercise improves cardiovascular health and lowers mortality, Dr. Rupa Sanghani, a cardiologist and director of the Heart Center for Women at Rush University System for Health in Chicago, told UPI via email.

"The most significant finding of the study is that women derive an even greater benefit than men do at the same level of physical activity," said Sanghani, who was not involved in the research.

"With the greater attention paid to women's heart health in recent years," she added, "we've learned much more about the physical differences between men and women's cardiovascular systems, and with more studies, our understanding will grow."

Dr. Heather Bergeson, a sports medicine physician and an assistant professor in the department of orthopedic surgery at the University of Minnesota Twin Cities in Minneapolis-St. Paul, told UPI via email that "strength training is also important, especially for women as we age and start to lose muscle mass and bone density."

Clinicians "previously recommended 150 minutes of moderately intense exercise per week, but this study shows that peak effect is 300 minutes per week," said Bergeson, who is also co-director of TRIA Women's Sports Medicine in Bloomington, Minn.

"Being active or on your feet at work does not count" toward that recommendation, Dr. Jacqueline Latina, a structural interventional cardiologist at Mount Auburn Cardiology Associates and Mount Auburn Hospital in Cambridge, Mass., told UPI via email.

"Many young to middle-aged women have trouble finding time to exercise with child care and other responsibilities," Latina said. "But this gives us data to encourage everyone to make the time for your own health because women in particular can benefit from increasing physical activity."

She added that "aiming to make areas more walkable should be a critical part of urban planning and development."
