Why You Always Sleep With One Foot Out of the Blanket

Your foot might be doing more than you think!

If you’re one of those people who always need to sleep with their feet out from under the covers, there’s actually a scientific reason for it. Sleep experts say it has to do with fine-tuning your body temperature. Even sticking just one foot out can help strike a balance between feeling too hot and too cold. Your feet have specialized blood vessels near the surface of the skin that help the body release heat faster. It also signals to your brain that it’s time to rest.
