All Your Clean Socks Are in the Wash
If you're like many women, you've probably noticed that your hands and feet are colder than your husband's when you climb into bed. This is because the nerves that control blood flow to these areas are more sensitive in women, and you were probably colder to begin with. The good news is that when our core body temperatures fall, our extremities tend to feel warmer as blood vessels dilate and the body radiates heat. To speed the process, try going to bed in clean, fresh socks (the ones you've been wearing all day are probably damp) and, if you need them, mittens. Instead of using your husband as a foot warmer, try using an actual hot water bottle, which won't protest or squirm away.
