Most of us know the many physical benefits of exercise like increased energy, weight control, lower blood pressure, and reduced risk of diabetes. But what about the psychological benefits of exercise? Did you know that exercise can help lessen symptoms of depression and anxiety and keep your memory sharp? Let’s explore six mental health benefits of exercise.
6 Mental Health Benefits of Exercise
Exercise and Depression
Studies show that exercise can treat mild to moderate depression as effectively as antidepressant medication but without any side effects. For example, a study by Harvard’s School of Public Health found that walking for an hour or running for 15 minutes a day reduces the risk of major depression by 26%. In addition to relieving symptoms of depression, research also shows that maintaining an exercise schedule can prevent you from relapsing. Some researchers suspect exercise alleviates chronic depression by increasing serotonin, the neurotransmitter targeted by antidepressants. Furthermore, exercise promotes all kinds of changes in the brain, like reduced inflammation, neural growth, and new activity patterns that promote feelings of well-being and calm. Additionally, exercise helps with good blood flow, improves circulation, and stimulates the growth of new blood vessels in the brain. In addition, physical exercise releases endorphins, powerful chemicals in your brain that energize your spirits and make you feel good. Finally, exercise can also serve as a distraction, since it provides some quiet time to break out of the cycle of negative thoughts that feed depression.
Exercise and Anxiety
Exercise is a natural and effective anti-anxiety treatment. It relieves stress and tension, boosts mental and physical energy, and enhances well-being by releasing endorphins, peptides produced in the brain that block the perception of pain and increase feelings of well-being. Furthermore, moving your body decreases muscle tension, lowering the body’s contribution to feeling anxious. In addition, exercise activates frontal regions of the brain that are responsible for executive function, and therefore helps control the amygdala, our reacting system to real or imagined threats to our survival.
One possibility is that exercise buffs up the brain and the body. Physical exercise triggers the release of a protein known as brain-derived neurotrophic factor (BDNF). BDNF encourages the growth of new brain cells, possibly, in the hippocampus, a brain region important in learning and memory. Since the hippocampus tends to be smaller or distorted in people with anxiety and depression, boosting BDNF through exercise might be a way physical activity might help manage these conditions.
Decreased Stress Another mental benefit of exercise is reduced stress levels, something that can make everyone happier. Increasing your heart rate can reverse stress-induced brain damage by stimulating the production of neurohormones like norepinephrine, which improves cognition and mood and clouded thinking by stressful events. In addition, exercise forces the body’s central and sympathetic nervous systems to communicate with one another, improving the body’s overall ability to respond to stress.
Think about how your body feels when you're stressed. Your muscles may be tense, especially in your neck and shoulders, leaving you with back or neck pain, or painful headaches. You may feel a tightness in your chest, a pounding pulse, or muscle cramps. You might also experience problems such as stomachache, insomnia, heartburn, diarrhea, or frequent urination. The worry and discomfort of all these physical symptoms can lead to even more stress, creating a vicious cycle between your mind and body.
Exercising is an effective way to break this cycle. As well as releasing endorphins in the brain, physical activity helps to relax the muscles and relieve tension in the body. Since the body and mind are so closely linked, when your body feels better so will your mind.
Increased Self-Esteem and Self-Confidence From improving endurance to losing weight and increasing muscle tone, there’s no shortage of physical achievements due to regular exercise. All those achievements can add up to boosting your self-esteem, as well as the confidence that comes with it. You may not set out for a slimmer physique or the ability to climb a hill without getting winded. Oftentimes it happens before you even realize it. It’s just one of the many benefits of physical activity that boost your body, mind, and spirit.
Regular exercise is an investment in your mind, body, and soul. When exercise becomes a habit, it can foster your sense of self-worth and make you feel strong and powerful. You’ll feel better about your appearance and, by meeting even small exercise goals, you’ll feel a sense of achievement.
Self-esteem is how we feel about ourselves and how we perceive our self-worth. It is a key indicator of our mental well-being and our ability to cope with life stressors. Physical activity has been shown to influence our self-worth and self-esteem positively. This relationship has been found in children, adolescents, young adults, adults, and older people, and among both males and females.
Better sleep Studies have found that proper exercise can alleviate sleep-related problems and help you get an adequate amount of rest. If you have trouble getting a good night’s sleep, exercise can help with that, too. Physical activity increases body temperature, which can have calming effects on the mind. Exercise also helps regulate your circadian rhythm, our body’s built-in alarm clock that controls when we feel tired and when we feel alert. Please note that sleep experts recommend not exercising close to bedtime.
Moderate aerobic exercise increases the amount of slow-wave sleep you get. Slow-wave sleep refers to deep sleep, where the brain and body have a chance to rejuvenate. In addition, moderate to vigorous exercise can increase sleep quality for adults by reducing sleep onset, and the time it takes to fall asleep, and decreasing the amount of time they lie awake in bed during the night. Additionally, physical activity can help alleviate daytime sleepiness. Exercise can also help to stabilize your mood and decompress the mind.
Brain Boost From building intelligence to strengthening memory, exercise boosts brainpower in many ways. Studies on mice and humans indicate that cardiovascular exercise creates new brain cells, a process called neurogenesis, and improves overall brain performance. Exercise also prevents cognitive decline and memory loss by strengthening the hippocampus, the part of the brain responsible for memory and learning. In addition, studies prove that physical activity boosts creativity and mental energy. So if you need inspiration, your big idea could be just a walk or jog away.
Exercise offers short-term boosts in cognition. Studies show that immediately after a bout of physical activity, people perform better on tests of executive functions and working memory. This might be in part because movement increases the release of neurotransmitters in the brain, most notably epinephrine and norepinephrine.
The brain benefits start to emerge, though, when people work out consistently over time. Studies show that people who work out several times a week have on average higher cognitive test scores, than people who are more sedentary. Other research has found that a person’s cognition tends to improve after participating in a new aerobic exercise program for several months.
Overall, there are many important mental health benefits of exercise. I hope you learned something new in this blog that helps motivate you to make time for exercise and wellness. Permit yourself to prioritize time to exercise. Learn to focus on your schedule and be sure to make time for wellness. You can walk during your lunch break, find some YouTube exercise videos that you’ll do after work or classes, go biking or hiking on the weekends, or join a gym. As exercise becomes a habit in your life, you’ll reap the benefits of exercise.
