Earth Gauge: Frostbite
When cold weather freezes fingers, toes, ears and noses, it causes the irreperable tissue damage we know as frostbite. The ice crystals that form inside these extremities puncture and destroy cells, as the outside flesh turnes white or grayish-yellow and becomes firm and waxy. When windchill values drop below zero degrees Fahrenheit, exposed skin can freeze in as little as five minutes.
Viewer Tip: The best way to guard against frostbite is to keep susceptible areas of your body covered. Hats, gloves, ear muffs and ski masks will help to protect your body parts from freezing temperatures, so don’t leave home without them! If you do experience frostbite, use frictionless warming methods such as body heat contact or submerge affected areas in warm water. Do not rub or massage frostbitten body parts or cover in hot water – these actions can cause further damage to body tissues. Have a health care provider evaluate frostbitten areas.
