Does Exercise Really Beat Depression?
(Ivanhoe Newswire) — Studies pointing to the benefits of exercise are numerous; with a large number of those revealing exercise can help some people overcome depression. A new report, from Harvard Medical School in Boston, says the connection between exercise and depression is not that cut and dry.
The report, published in the Harvard Mental Health Letter, explores possible explanations for the observed connection. Researchers note exercise may improve depression because it enhances body image, serves as a distraction from everyday worries, and provides social support through exercise groups. Additionally, exercise can heighten a person’s self-confidence by allowing them to reach a set goal, and is found to alter circulation of endorphins and the feel-good hormones serotonin and norepinephrine and.
In their report, however, researchers suggest the benefits of exercise on mental health may be an illusion. They point out, studies suggesting a connection between to two overlook the possibility depression and anxiety can prevent people from exercising. They say people who have depressed personalities also usually have sedentary lifestyles.
Despite these doubts about the role of exercise in improving mental illness, researchers note exercise has many health benefits and does little harm. They encourage people who are depressed to begin slowly and remember that exercise does not have to be strenuous to be effective.
