Information on Frostbite
Frostbite can cause permanent damage to skin and underlying tissues, even when medically treated, if it is severe enough. It occurs when the tissue temperature falls below the freezing point. High winds increase the chances and rate of frostbite. It can occur in 30 minutes with the temperature at 10 degrees F.
