Normal or not, wearing socks may be smart if you’re having trouble falling asleep. There may be something to the old advice that warming your feet can speed up your trip to dreamland.
Heating cold feet causes vasodilation—dilation of the blood vessels—which may tell the brain that it is bedtime. After the blood vessels open in the hands and feet, heat is redistributed throughout the body to prepare for sleep.
In fact, some research has shown that the more vasodilation in the hands and feet, the less time it takes to fall asleep. The relationship between warm hands and feet and falling asleep may be what’s behind the age-old belief that placing a hot water bottle at the foot of the bed is good for sleep.
The verdict? Socks in bed may not be sexy, but then again, neither are cold feet!
