Quick Answer
Keeping hands dry in winter is crucial to prevent frostbite and hypothermia. When hands are wet, the water molecules conduct heat away from the skin, lowering its temperature at an alarming rate. Dry hands are essential to maintain blood circulation and prevent freezing temperatures from damaging skin tissues.
Protecting Against Frostbite
Frostbite sets in when skin temperature drops below 32°F (0°C). Exposed wet skin can freeze in as little as 5-10 minutes in freezing temperatures. To prevent this, apply a waterproof barrier, such as a pair of insulated gloves or mittens. When gloves get wet, change into dry ones immediately. In extreme conditions, wear multiple layers of clothing to trap warm air and maintain body heat.
Preventing Hypothermia
Hypothermia occurs when your body loses heat faster than it can produce it. Wet skin accelerates this process, making it essential to keep hands dry. Apply a thin layer of petroleum jelly or lip balm to exposed skin to prevent moisture from penetrating. In severe cases, use a hand warmer or a small hot water bottle wrapped in a towel to warm up your hands. Monitor your body temperature and seek medical attention if your hands turn white, blue, or numb.
