How Much Sleep is Good for Your Heart?

Read Transcript

Hi, I'm Dr. Miller. Do you know how much sleep you need for a healthy heart? It turns out there's such a thing as too much and too little sleep. Recent data from the American College of Cardiology finds that people who sleep less than six hours a night have a higher risk of stroke, heart attack and heart failure.

Previous research has linked getting too little sleep to diabetes, hypertension and inflammation, all of which contribute to heart disease. But people who sleep more than eight hours a night aren't much better off. They are twice as likely to have chest pains called angina. they're all somehow likely to have coronary artery disease.

Experts don't know why too much sleep messes with your heart, but if you are having trouble sleeping or sleeping more than you should, let your doctor know. Sleep disorders such as insomnia or sleep apnea may be getting in the way of a good night's rest, and in the way of your heart health.
