Wearing socks to bed: Yay or nay?

There are two types of people in this world: those who wear socks to bed and those who don't. It turns out that the decision could be the difference in who is getting a good night's sleep. The National Sleep Foundation says having warm feet signals the body that it's time to relax. It has to do with blood vessels dilating when they're warmed up. If wearing socks is still a hard pass for you, the National Sleep Foundation says you can get similar results by layering an extra blanket at the end of your bed.
