The reason: Too much sleep could kill you, according to scientists.
A global study released by the European Heart Journal reports that sleeping more than the recommended six to eight hours a night increased subjects' risk of stroke, heart failure and other cardiovascular problems, as well as death, by as much as 41 percent. The study attracted attention because of its scope: data came from 116,613 people, ages 35 to 70, from 21 countries. Over a period of 7.8 years, 4,381 deaths and 4,365 major cardiovascular events were reported.
