Go back to bed! It could lower your stroke risk

Many of us could probably use more sleep — 30 percent of working adults regularly get less than six hours of shut-eye a night, after all. And a new study shows that need may be even more urgent than we'd realized. According to researchers, people who sleep less than six hours are four times more likely to suffer a stroke than those who sleep seven or eight, even if their body weight is normal and they have no other risk factors. Lead author Megan Ruiter, from the University of Alabama, said: "The really important take-home message is this: Don't blow it off. Sleep is just as important as diet and exercise." Might want to hit the sack a bit earlier tonight.
