Stress is an inevitable part of life. Seven out of ten adults in the United States say they experience stress or anxiety daily, and most say it interferes at least moderately with their lives, according to the most recent ADAA survey on stress and anxiety disorders. When the American Psychological Association  surveyed people in 2008, more people reported physical and emotional symptoms due to stress than they did in 2007, and nearly half reported that their stress has increased in the past year.
It’s impossible to eliminate, but you can learn to manage stress,  and most people usually do. According to a recent ADAA online poll, some 14 percent of people make use of regular exercise to cope with stress. Others reported talking to friends or family (18 percent); sleeping (17 percent); watching movies or TV (14 percent), as well as eating (14 percent) and listening to music (13 percent).
While all of these are well-known coping techniques, exercise may be the one most recommended by health care professionals. And among ADAA poll takers who exercise, a healthy percentage is already on the right track: Walking (29 percent), running (20 percent), and yoga (11 percent) are their preferred strategies.
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.
