Whether or not it's acceptable to wear socks to bed is a shockingly divisive issue — much like whether or not it's OK to eat raw cookie dough or put ketchup on eggs. But sock supporters, rejoice: Not only is it totally fine to wear socks to bed, but experts say it might help you sleep better. Ha! (Full disclosure: We're very much #TeamSock.)
During a February 2016 appearance on the TODAY show, NBC News medical contributor Natalie Azar, MD, suggested that pulling on a pair of socks might help our bodies "initiate sleep" — and, as it turns out, the National Sleep Foundation (NSF) agrees.
Warming up your cold feet with socks can actually send a signal to your brain that it's bedtime, according to the NSF. That's because the blood vessels in your feet start to dilate (aka open up) in a process called vasodilation, which helps to redistribute that heat throughout the body and get you ready for sleep.
A small March 2000 study published in Regulatory, Integrative, and Comparative Physiology even suggests that this vasodilation in the feet might help us fall asleep faster than we would if we weren't warming up our toes.
If you kind of want to try out this vasodilation thing but still can't get behind the idea of wearing socks in bed, fret not! The NSF has a few other ideas for heating up your feet pre-bedtime: Layering extra blankets at the bottom of your bed, using a hot water bottle or heating pad, or wearing slippers before you hit the hay should all do the trick.
But bedtime socks are clearly superior. Just sayin'.
