Of the following, which does NOT help prevent heart disease?
- Controlling blood pressure
- Eating lots of fruits and vegetables
- Exercising regularly
- Sleeping eight hours a night
- Quitting smoking
"There are many good reasons to get eight hours of sleep a night," says Lawrence Friedman, M.D., special assistant to the director of the NIH's National Heart, Lung and Blood Institute (NHLBI). "But heart-disease prevention is not one of them." Controlling blood pressure, quitting smoking, exercising regularly and eating lots of fruits and vegetables have all been shown to help prevent heart disease. Other heart helpers include eating fish rich in omega-3s, such as salmon, and keeping your cholesterol low.
