We got a press release from NOAA talking about the weather in DC on inauguration day.
Towards the bottom was good information on recognizing frostbite:
- Frostbite is damage to body tissue caused by exposure to extreme cold. Warning signs include a loss of feeling and a white or pale appearance in extremities, such as fingers, toes, ear lobes or the tip of the nose.
Extremities are the first thing frostbite goes after, so cover up ears, nose, fingers, etc.. IF you suspect frostbite and don’t do anything, numbness will spread as the freezing continues. And, though it’s done in the movies, don’t rub frostbitten areas re:it could cause further damage to the skin. Instead, move indoors to warm up or put the affected area under warm water (not hot water, warm water…).
Survive Outdoors has some good info on frostbite symptoms and treatment.
