Study: Blood pressure linked to sleep

August 30, 2011

A new study finds men with the lowest level of the deeper stages of sleep known as slow wave sleep had an 80 percent higher chance of developing high blood pressure. No one knows exactly why.

But scientists say that when you go to sleep, blood pressure normally falls, and a lot of that fall occurs during slow-wave sleep. But when that typical drop in night time pressure is affected by a lack of deep sleep, it may set you up for daytime elevations.

Experts say that anything that wakes you up repeatedly will disrupt your slow wave sleeps, even sleep apnea. So, it's good to get treated.
