Your feet stay warmer while wearing a hat on your head

Do you have cold feet? Try throwing a hat on to warm them up. When the body is cold, the first thing it does is send extra blood to the head to heat it up because it is worried the brain will get too cold. This means a lack of blood to the extremities, and cold hands and feet quickly ensue. When you put a warm hat on, it protects your head from the cold and allows your body to disperse heat more evenly.
