Are you a woman who is between 50 and 79 years of age? Do you like to sleep a lot? Well, if you are, you might want to examine your sleeping patterns. A recent study conducted by researchers at the University of North Carolina in Chapel Hill reveals that too much sleep can increase the risk of stroke in middle-aged women.
A report by Reuters states:
The greatest increase in stroke risk — 70 percent — was noted among women who slept 9 hours or more per night, according to their report in the medical journal Stroke.
After following the group for an average of 7.5 years, the researchers found that 1,166 women experienced an ischemic stroke, the most common type of stroke, which occurs when a blood vessel in the brain becomes blocked. This prevents oxygen from reaching the brain and the brain’s tissue begins to die.
Upon further analysis, Chen’s group found that women with a sleep duration of 6 hours or less, 8 hours, or 9 hours or more increased the risk of stroke by 14 percent, 24 percent, and 70 percent, respectively, compared with sleeping 7 hours.
However, the study does not conclusively state that if women lessen their sleeping hours, their risk of stroke will be lower. Chen further states:
Our data do not imply that if women with long sleep cut their sleep hours they would be at a lower risk….Further studies are needed to help us understand the possible mechanisms involved in the associations found in this study.
Sometimes I wish that they would conduct further studies to give more conclusive information before releasing the results to the general public!
