Sleep
Too much sleep could increase the risk of a stroke. Researchers at the University of Cambridge found people who slept more than 8 hours a night were 46% more likely to suffer a stroke, compared to those who slept 6 to 8 hours a night. Doctors say more research is needed to determine the link.
