The physical benefits of exercise—improving physical condition and fighting disease—have long been established, and physicians always encourage staying physically active. Exercise is also considered vital for maintaining mental fitness, and it can reduce stress. Studies show that it is very effective at reducing fatigue, improving alertness and concentration, and at enhancing overall cognitive function. This can be especially helpful when stress has depleted your energy or ability to concentrate.
When stress affects the brain, with its many nerve connections, the rest of the body feels the impact as well. So it stands to reason that if your body feels better, so does your mind. Exercise and other physical activity produce endorphins—chemicals in the brain that act as natural painkillers—and also improve the ability to sleep, which in turn reduces stress. Meditation, acupuncture, massage therapy, even breathing deeply can cause your body to produce endorphins. And conventional wisdom holds that a workout of low to moderate intensity makes you feel energized and healthy.
Scientists have found that regular participation in aerobic exercise has been shown to decrease overall levels of tension, elevate and stabilize mood, improve sleep, and improve self-esteem. Even five minutes of aerobic exercise can stimulate anti-anxiety effects.
Among some of its additional benefits, exercise can help:
- strengthen your muscles and bones
- strengthen your immunity, which can decrease your risk of illness and infection
- lower your blood pressure, sometimes as much as some antihypertensive medications
- boost levels of good cholesterol in your blood
- improve your blood circulation
- improve your ability to control weight
- help you sleep better at night
- boost your energy
- improve your self-image
