Do you wear socks to bed? Research has found that wearing warm socks can raise foot temperature by an average of 1.3°C, which improves blood circulation and body temperature distribution, thus helping to fall asleep faster and reduce night wakings.
In a randomized controlled trial, subjects who wore warm socks fell asleep an average of 7.5 minutes shorter, slept 32 minutes longer, woke up 7.5 times less, and had a 7.6% increase in overall sleep efficiency.
