In serious cases, depression is a symptom of mental illness. Exercise is often used in the treatment of mild depression and anxiety. Research has shown that aerobic exercise sustained for at least 30 min, five times a week can have anti-depressant effects, and the exercise produces physiological benefits that extend the range of activities that the patient can undertake with ease. Some of the psychological benefits are probably linked to an improved general feeling of well-being. In contrast, severe overtraining has been found to produce signs of depression in some athletes.
