Did you know that not getting enough sleep could raise your blood pressure? That appears to be the case for middle aged adults. In a recent study, adults that got less than six hours of sleep were forty percent more likely to develop high blood pressure than people that got more than 6 hours.

The study was done by researchers at the University of Chicago and took place over a period of five years. It looked at over 600 hundred adults with an average age of forty. Overall, only a small percent of the subjects reported getting the 7-9 hours recommended by the CDC. Most average only 6 hours per night. But, even those that only got 1 hour less were significantly at risk for developing high blood pressure.

The study doesn't explain why less sleep results in high blood pressure. But other reports speculated that because blood pressure falls during sleep, less sleep deprives the body of a kind of blood pressure break. Over time, that could lead to higher blood pressure.

And now you know.
