Why is exercise good for us? Among other facts, exercise decreases the risk of coronary heart disease, stroke, and various cancers; lowers blood pressure, reduces problems related to diabetes, assists in the maintenance of bone density, and improves your immune system!
But did you know that exercise is also good for our psyches?
In a 1990 analysis of eighty studies on exercise and depression, a research team that included psychologist Penny McCullagh, PhD, reached the following conclusions:
Exercise reduced depression especially for those most physically and/or psychologically unhealthy and over age 55 years
Exercise was an equally effective antidepressant for both men and women
Walking and jogging were the most frequent forms of exercise that had been researched, but all modes of exercise, anaerobic as well as aerobic, were effective in lessening depression.
The longer the exercise program and the more exercise sessions, the greater the decrease in depression.
The most powerful antidepressant effect occurred with the combination of exercise and psychotherapy.
So find a way to increase your physical activity and consult an expert therapist to help you figure out and learn ways to reduce your depression.
