Moderate exercise can prevent depression
It’s well known that exercise releases endorphins, making people feel better and happier after a good workout. But the positive effects of exercise go beyond the short term and may actually lessen your chances of developing depression in later years.
A review published in the American Journal of Preventive Medicine suggests a clear link between moderate exercise and preventing depression in the long run. It's the first longitudinal review on the direct relationship between exercise and depression over many years. The research showed that even low levels of exercise, such as walking for 20 minutes a day, can prevent depression in people of all ages.
While lead researcher George Mammen acknowledges that several factors can influence a person’s chances of developing depression--such as genetics--the findings may be helpful for developing prevention strategies and treating depression without medication.
