I first saw this theory in the classic horror flick “The Haunting.” A woman purposely sleeps on her left side all the time because it wears out the heart sooner, and she’d just as soon die sooner.
I’ve heard the idea other places too, though. I can’t think of many specific instances, but it’s in the ether of my brain and memory. And some doctor or other once advised me to sleep on my right side because it…drained something better…or something. You see I’m very thorough here.
My positing this question stems purely from personal paranoia. Lately I’ve felt much more comfortable curling up (slightly) onto my left side when falling asleep.
My normally trusty friend Google yields conflicting results. A Yahoo! answers page advises a woman whose baby has a heart ailment not to let her baby sleep on its left side. Some alternative health sources point out extra pressure that can be put on the heart by the right lung, e.g. But an MSN health thread claims: “‘There is no clinical evidence that sleeping in a given position is bad or good for the heart,’ says Dr. Richard Stein, director of preventive cardiology at Beth Israel Hospital in New York City and national spokesman for the American Heart Association. ‘Whatever position is most restful is probably right for the individual.’"
I know, I know…that last one sounds pretty definitive. But my paranoid brain reads “no clinical evidence” as “we just haven’t bothered to run clinical trials or studies about it yet.”
I dunno. Any insights?
I should go to sleep now. And it will probably be on my left side.
