How Does Exercise Improve Mental Health?

We know that exercise has positive effects on the brain. Researchers at Duke University demonstrated several years ago that exercise has antidepressant properties. Other research has shown that exercise can improve the brain functioning of the elderly and may even protect against dementia. How does exercise improve mental health?
One theory for some of the benefits of exercise include the fact that exercise triggers the production of endorphins. These natural opiates are chemically similar to morphine. They may be produced as natural pain relievers in response to the shock that the body receives during exercise. However, researchers are beginning to question whether endorphins improve mood. Studies are showing that the body's metabolism of endorphins is complex, and there are likely additional mechanisms involved in the mental health effects of exercise.
