Six to eight hours of sleep best for the heart, says study

Research shows sleep deprivation or excessive hours in bed increase risk of coronary artery disease or stroke

Six to eight hours of sleep a night is most beneficial for the heart, while more or less than that could increase the risk of coronary artery disease or a stroke, researchers have suggested.

The study, presented at the European Society of Cardiology Congress in Munich, indicates sleep deprivation and excessive hours in bed should be avoided for optimum heart health.
