Put cotton or gauze between frostbitten fingers and toes. Never rub an affected area-rubbing causes further damage. Being knowledgeable about the weather can help reduce your risk. For example, wind chill factors are more relevant than uncorrected temperatures because wind has a marked effect on heat loss. So even when the temperature itself is not very low, the wind chill factor may be low enough to warrant staying inside.
Proper clothing is important in preventing frostbite because it insulates the body.
Wear loose-fitting, warm, light weight clothing in several layers rather than one bulky sweater or jacket. Trapped air insulates, and layers can be removed to avoid perspiration and subsequent chill. Outer garments should be tightly woven, water repellent, and hooded. Mittens are better for warmth than gloves. Cover vulnerable areas such as cheeks, nose and mouth.
