"Exercise on par with drugs for aiding depression
By Amy Norton Wed Sep 19, 3:20 PM ET
NEW YORK (Reuters Health) - Regular exercise may work as well as medication in improving symptoms of major depression, researchers have found.
In a study of 202 depressed adults, investigators found that those who went through group-based exercise therapy did as well as those treated with an antidepressant drug. A third group that performed home-based exercise also improved, though to a lesser degree.
Importantly, the researchers found, all three groups did better than a fourth group given a placebo -- an inactive pill identical to the antidepressant.
While past studies have suggested that exercise can ease depression symptoms, a criticism has been that the research failed to compare exercise with a placebo. This leaves a question as to whether the therapy, per se, was responsible for the benefit.
The new findings bolster evidence that exercise does have a real effect on depression, according to the researchers.
Doctors may not start widely prescribing exercise as a depression treatment just yet. But for patients who are motivated to try exercise, it could be a reasonable option, the study authors say...."
Simply taking a walk and looking at things helps, too.
