Bring your child indoors immediately. Remove all wet clothing. Wet clothes draw heat away from the body. Immerse chilled body parts in warm (not hot) water for 20 to 30 minutes until all sensation returns. Don't let your child control the water temperature during rewarming. Numb hands won't feel the heat and can be severely burned by water that is too hot. Body heat also can be used to rewarm. Don't use heating pads, stoves, fireplaces, or radiators to rewarm because the affected skin can be numb and easily burn. Call your doctor if sensation does not return or there are signs of frostbite and/or hypothermia.
