Frostbite
Frostbite can occur without hypothermia when the extremities do not receive sufficient heat from central body stores.
What Does Frostbite Do
To Your Body?
This can occur because of inadequate circulation and/or insulation.
- Frostbite occurs when there is freezing of the fluids around the cells of the body tissues due to extremely low temperatures.
- Frostbite may result in damage to and loss of tissue and usually affects the nose, cheeks, ears, fingers, and toes.
- Damage from frostbite can be serious and includes scarring, tissue death resulting in amputation, and permanent loss of movement in the affected parts).
The freezing point of the skin is about 30F (-1°C). As wind velocity increases, heat loss is greater, and frostbite will occur more rapidly. If skin meets objects colder than freezing (e.g., tools or machinery), frostbite may develop at the point of contact, even in warmer environments.
