Exercise may reduce mild to moderate depression and, in many cases, may be as effective as psychotherapy. Either brief periods of intense training or prolonged aerobic workouts can raise chemicals in the brain, such as endorphins, adrenaline, serotonin, and dopamine, that produce the so-called runner's high. Physical activity, particularly rhythmic aerobic and yoga exercises, helps combat stress and anxiety. And, of course, weight loss and increased muscle tone can boost self-esteem. A strong network of social support is both important for prevention and recovery from depression.
Studies indicate that people with strong spiritual faiths have a lower risk for depression.
Such faith does not require an organized religion. People with depression might find solace from less structured sources, such as those that teach meditation or other methods for obtaining spiritual self-fulfillment.
