Excessive Sleep May Raise Risk of Stroke

PositiveTips

Analysis of data from the Harvard Nurses' Health Study has revealed that women who sleep 10 hours or more a night are 63% more likely to suffer a stroke over a 20 year period than those getting 7-8 hours of sleep.

Women who got 6 or fewer hours of sleep per night also had an elevated risk of stroke, but it was not statistically significant. Investigators do not know why this occurs, but suggest extra sleep may be a marker for some other causal factor.

PositiveTip: Adequate sleep for most people is probably in the 7.5-8.5 hour per night range. Are you getting enough?
