Cold feet might be the reason behind your restless nights. When your feet are cold, they constrict the blood vessels and cause less blood to circulate. According to the National Sleep Foundation, warming your feet before you go to bed helps give your brain a clear sleep signal that it’s bedtime.

And the easiest way to warm your feet? Socks. Wearing socks in bed is the safest way to keep your feet warm overnight. Other methods such as rice socks, a hot water bottle, or a heating blanket may cause you to overheat or get burned.
