Exercise is defined as any movement that makes your muscles work and requires your body to burn calories.
There are many types of physical activity, including swimming, running, jogging, walking and dancing, to name a few.
Being active has been shown to have many health benefits, both physically and mentally. It may even help you live longer (1).
Here are the top 10 ways regular exercise benefits your body and brain.
It produces changes in the parts of the brain that regulate stress and anxiety. It can also increase brain sensitivity for the hormones serotonin and norepinephrine, which relieve feelings of depression (1).
Additionally, exercise can increase the production of endorphins, which are known to help produce positive feelings and reduce the perception of pain (1).
Furthermore, exercise has been shown to reduce symptoms in people suffering from anxiety. It can also help them be more aware of their mental state and practice distraction from their fears (1).
Interestingly, it doesn’t matter how intense your workout is. It seems that your mood can benefit from exercise no matter the intensity of the physical activity.
In fact, a study in 24 women who had been diagnosed with depression showed that exercise of any intensity significantly decreased feelings of depression (3).
The effects of exercise on mood are so powerful that choosing to exercise (or not) even makes a difference over short periods.
One study asked 26 healthy men and women who normally exercised regularly to either continue exercising or stop exercising for two weeks. Those who stopped exercising experienced increases in negative mood (4).
SUMMARY:Exercising regularly can improve your mood and reduce feelings of anxiety and depression.
To understand the effect of exercise on weight reduction, it is important to understand the relationship between exercise and energy expenditure.
Your body spends energy in three ways: digesting food, exercising and maintaining body functions like your heartbeat and breathing.
While dieting, a reduced calorie intake will lower your metabolic rate, which will delay weight loss. On the contrary, regular exercise has been shown to increase your metabolic rate, which will burn more calories and help you lose weight (5, 6, 7, 8).
Additionally, studies have shown that combining aerobic exercise with resistance training can maximize fat loss and muscle mass maintenance, which is essential for keeping the weight off (6, 8, 9, 10, 11).
SUMMARY:Exercise is crucial to supporting a fast metabolism and burning more calories per day. It also helps you maintain your muscle mass and weight loss.
Exercise plays a vital role in building and maintaining strong muscles and bones.
Physical activity like weight lifting can stimulate muscle building when paired with adequate protein intake.
As people age, they tend to lose muscle mass and function, which can lead to injuries and disabilities. Practicing regular physical activity is essential to reducing muscle loss and maintaining strength as you age (14).
Interestingly, high-impact exercise, such as gymnastics or running, or odd-impact sports, such as soccer and basketball, have been shown to promote a higher bone density than non-impact sports like swimming and cycling (16).
SUMMARY:Physical activity helps you build muscles and strong bones. It may also help prevent osteoporosis.
One study found that six weeks of regular exercise reduced feelings of fatigue for 36 healthy people who had reported persistent fatigue (19).
In fact, exercise seems to be more effective at combating CFS than other treatments, including passive therapies like relaxation and stretching, or no treatment at all (20).
Additionally, exercise has been shown to increase energy levels in people suffering from progressive illnesses, such as cancer, HIV/AIDS and multiple sclerosis (21).
SUMMARY:Engaging in regular physical activity can increase your energy levels. This is true even in people with persistent fatigue and those suffering from serious illnesses.
Lack of regular physical activity is a primary cause of chronic disease (22).
In contrast, a lack of regular exercise — even in the short term — can lead to significant increases in belly fat, which increases the risk of type 2 diabetes, heart disease and early death (23).
SUMMARY:Daily physical activity is essential to maintaining a healthy weight and reducing the risk of chronic disease.
Your skin can be affected by the amount of oxidative stress in your body.
Oxidative stress occurs when the body’s antioxidant defenses cannot completely repair the damage that free radicals cause to cells. This can damage their internal structures and deteriorate your skin.
Even though intense and exhaustive physical activity can contribute to oxidative damage, regular moderate exercise can increase your body’s production of natural antioxidants, which help protect cells (29, 30).
In the same way, exercise can stimulate blood flow and induce skin cell adaptations that can help delay the appearance of skin aging (31).
SUMMARY:Moderate exercise can provide antioxidant protection and promote blood flow, which can protect your skin and delay signs of aging.
Exercise can improve brain function and protect memory and thinking skills.
To begin with, it increases your heart rate, which promotes the flow of blood and oxygen to your brain.
It can also stimulate the production of hormones that can enhance the growth of brain cells.
Moreover, the ability of exercise to prevent chronic disease can translate into benefits for your brain, since its function can be affected by these diseases (32).
Lastly, exercise has been shown to reduce changes in the brain that can cause Alzheimer’s disease and schizophrenia (36).
SUMMARY:Regular exercise improves blood flow to the brain and helps brain health and memory. Among older adults, it can help protect mental function.
In regards to sleep quality, the energy depletion that occurs during exercise stimulates recuperative processes during sleep (38).
Moreover, the increase in body temperature that occurs during exercise is thought to improve sleep quality by helping it drop during sleep (39).
Many studies on the effects of exercise on sleep have reached similar conclusions.
One study found that 150 minutes of moderate-to-vigorous activity per week can provide up to a 65% improvement in sleep quality (40).
Another showed that 16 weeks of physical activity increased sleep quality and helped 17 people with insomnia sleep longer and more deeply than the control group. It also helped them feel more energized during the day (41).
You can be flexible with the kind of exercise you choose. It appears that either aerobic exercise alone or aerobic exercise combined with resistance training can equally help sleep quality (44).
SUMMARY:Regular physical activity, regardless of whether it is aerobic or a combination of aerobic and resistance training, can help you sleep better and feel more energized during the day.
Chronic pain can be debilitating, but exercise can actually help reduce it (45).
In fact, for many years, the recommendation for treating chronic pain was rest and inactivity. However, recent studies show that exercise helps relieve chronic pain (45).
A review of several studies indicates that exercise helps participants with chronic pain reduce their pain and improve their quality of life (45).
Several studies show that exercise can help control pain that’s associated with various health conditions, including chronic low back pain, fibromyalgia and chronic soft tissue shoulder disorder, to name a few (46).
SUMMARY:Exercise has favorable effects on the pain that’s associated with various conditions. It can also increase pain tolerance.
A group of women in their 40s observed that they experienced orgasms more frequently when they incorporated more strenuous exercise, such as sprints, boot camps and weight training, into their lifestyles (53).
Also, among a group of 178 healthy men, the men that reported more exercise hours per week had higher sexual function scores (50).
One study found that a simple routine of a six-minute walk around the house helped 41 men reduce their erectile dysfunction symptoms by 71% (54).
Another study performed in 78 sedentary men revealed how 60 minutes of walking per day (three and a half days per week, on average) improved their sexual behavior, including frequency, adequate functioning and satisfaction (55).
What’s more, a study demonstrated that women suffering from polycystic ovary syndrome, which can reduce sex drive, increased their sex drive with regular resistance training for 16 weeks (56).
SUMMARY:Exercise can help improve sexual desire, function and performance in men and women. It can also help decrease the risk of erectile dysfunction in men.
Exercise offers incredible benefits that can improve nearly every aspect of your health from the inside out.
Regular physical activity can increase the production of hormones that make you feel happier and help you sleep better.
It can also improve your skin’s appearance, help you lose weight and keep it off, lessen the risk of chronic disease and improve your sex life.
Whether you practice a specific sport or follow the guideline of 150 minutes of activity per week, you will inevitably improve your health in many ways (57).
