Being attacked by your partner's cold feet in bed is no fun. Now experts are saying you should just wear socks to bed. One such expert explains, "Heating cold feet causes vasodilation - dilation of the blood vessels - which may tell the brain that it is bedtime." So keeping those tootsies toasty could help you fall asleep faster, and you might even sleep better. Previous research published in the International Weekly Journal of Science says wearing socks to bed could help you fall asleep up to 15 minutes sooner than you typically do. (Mirror.co.uk)
