Can being positive make me healthier?

If you care about your physical well-being, try increasing your happiness—there is some scientific evidence it could make your life longer and healthier.

But to produce good health, positive emotions may need to be long-term. In other words, thinking positive thoughts for a month when you already have heart disease won't cure the disease. But lowering your stress level over a period of years with a positive outlook and relaxation techniques could reduce your risk of heart problems.
