A study was “pre-announced” on June 7 from the Henry Ford Hospital in Detroit regarding the link between hypertension and insomnia. It’s kind of vague, and relied on an “internet survey” for its results. A what??
This isn’t science. An internet survey about sleep that can draw relevant conclusions. Granted, I haven’t seen the study yet (to be presented June 12), but really.
ADDENDUM 6/25/2012: Tried to find the study online today and couldn’t – all the links were to the articles I talk about here. If anyone can actually find the published study, send me the link. Interesting, huh?
ADDENDUM to the ANNENDUM – later on 6/25/2012 – Hypnagog sent me a link to the abstract. I read it (not the whole study) and still have questions about the conclusions that can be drawn by an Internet survey. People self-reporting is bad. People self reporting about sleep is really bad.
When I heard this I did the next best thing – who else has looked at insomnia and hypertension. The study referred to the most one published in Sleep…
Insomnia and Hypertension Study
The Journal of Sleep published this study a few years ago and concluded that, in general, people that get less than six hours of sleep, or were frequently awoken at night were up to 500% more likely to have high blood pressure than those who slept six hours or more.
The study had it’s flaws, though:
- It didn’t differentiate properly the people in the study who suffered from severe obstructive sleep apnea, so it’s unclear how many subjects fell into that category.
- Once you treated the OSA (normally with CPAP), blood pressure levels returned to normal.
- With complex sleep apnea sufferers in the study, it wouldn’t be hard to find a statistically significant number of those people that had any number of severe health problems.
The recommendations for the next study that dives into this minefield would be to use any/all techniques and technology available to differentiate people suffering from a treatable medical condition – like sleep apnea, and regular insomnia. Hardly a study you could do on the internet.
My take on this news – ignore the study. Both of them.
