Getting a good night's sleep is important. But exactly how much sleep do you need? Recently, the American Heart Association added sleep to its checklist for improving and maintaining your heart health. Dr. Regis Fernandes, a Mayo Clinic cardiologist, explains how many hours of sleep people need for optimal heart health.
When it comes to sleep, it turns out quantity is just as important as quality.
"The reason why is studies have shown if you sleep less than seven hours a day, you have a higher cardiovascular risk or a risk for heart disease or stroke," says Dr. Fernandes.
