Exercise more

Want a cure-all? Try aerobic exercises like running, walking, swimming, and even dancing. These activities help you feel better, lower your risk for diabetes, and make your heart stronger, a trifecta of health benefits. Exercise can also help depression.

Study after study has shown the benefits of physical activity, even active housework or gardening. The reason? It pumps your heart, moving blood all around the body.

The American Heart Association recommends exercising aerobically at least 30 minutes all or most days of the week. But talk to your doctor before hitting the track.
