Moderate exercise may help ward off depression.

Depression affects millions of Americans to varying degrees and extends far beyond a simple case of the doldrums. This psychological disorder can lead you to pull away from the ones you love and may rob you of the joy you once took from your favorite activities. While anti-depressants and therapy are common options when it comes to treating this issue, some of the day-to-day choices you make can also have a beneficial impact. Previously on this blog, we've discussed the potential benefits of omega-3 fatty acids both as a source of nutrition for the brain and as a natural mood-booster. Now, researchers have found that engaging in regular exercise may keep this behavioral condition at bay and even prevent it.

According to a press release distributed by ScienceDaily, University of Toronto PhD candidate George Mammen has published a review on the positive effects of moderate exercise on brain health and depression risk.

Given that one in 10 adults report instances of depression, according to U.S. Centers for Disease Control and Prevention statistics, Mammen argues that there is no time to lose regarding the prevention of this costly and destructive ailment. 

"We need to shift focus [from simple treatment] and look for ways to fend off depression from the start," he said in the release.

Based on Mammen's review of years worth of research, he and his colleagues concluded that exercising from 20 to 30 minutes a day may help limit the risk of developing depression, though further investigation is necessary to confirm this finding.
