The book, The Healing Power of Exercise: Your Guide to Prevention and Treating Diabetes, Depression, Heart Disease, High Blood Pressure, Arthritis, and More states, “A universal finding in exercise studies is that people experience a greater sense of wellbeing.” In the book, it is explained, “Our cardiovascular system, endocrine glands, muscles, and bones still function best when the body is challenged by regular
bouts of exertion.”

Exercise enhances your mood in many ways. Although exercisers exercise for a wide variety of reasons, the most powerful reasons are psychological, not physical. Exercisers have found exercise makes them:
feel good. more optimistic. more mentally alert. feel an enhanced sense of well-being. feel more confident. better able to cope with stress and more energetic.

Moreover, some people report they overeat because they are depressed. For many, moderate depression tends to cause overeating while severe depression tends to cause undereating. One large study of overweight individuals found depression was the number one reason for overeating, ahead
of stress.
