Less Deep Sleep Could Lead to Higher Blood Pressure, Study Finds

Stockbyte/Thinkstock(BOSTON) -- A bad night's sleep could lead to higher blood pressure, a new study suggests.

Researchers found that men who got less deep sleep, also called slow-wave sleep, had an 80-percent higher chance of having high blood pressure compared to men with higher levels of slow-wave sleep.  The researchers added that this connection held true notwithstanding other factors like obesity, race or age.

While the percentage of deep sleep one experiences does decrease with age, investigators found that participants in the study, which included more than 780 men with an average age of 75, with the lowest percentage of slow-wave sleep developed high pressure in more cases.

The study, published Monday in the journal Hypertension, did not confirm a causal relationship between deep sleep and high blood pressure.
