It reduces your risk of the common cold
istock/AlexRaths A consistent, medium-intensity routine is a proven cold-stopper. Taking a brisk, 40-minute walk 4 days a week, for example, can cut the number of colds you experience by 25 to 50 percent and can make the colds you do catch shorter by half, studies show. Moderate exercise boosts the number and activity level of important immune-system players called natural killer cells.
It improves depression without drugs
istock/max-kegfire The warning signs of depression can sneak up on you, but there are ways to help treat it naturally. One study divided men and women with depression into three groups: One followed an aerobic exercise program, one took the antidepressant sertraline (Zoloft), and the third did both. After four months, all participants had about the same improvement in their depression, suggesting that exercise could be an acceptable substitute for antidepressants. A follow-up showed that those who kept exercising regularly after the study, regardless of what their treatment was, were less likely to relapse into depressive episodes.
