Answer
When the body is in a cold environment, most of the body's energy is used to keep your internal temperature warm. Over time, your body will begin to shift blood from the extremities (hands, feet) and outer skin to the core (center) of the body.This process allows the exposed skin to cool rapidly and increases the risk of frost-bite.
