Frostbite - Description



Frostbite is caused by exposure to temperatures well below freezing (32°F or 0°C). Dry conditions contribute to frostbite damage. At temperatures closer to freezing, frostnip is more likely to occur. Humid air is also more likely to produce frostnip than frostbite.

In North America, frostbite occurs most frequently in Alaska, Canada, and the northernmost regions of the United States. In recent years, the number of cases of frostbite and frostnip have decreased considerably. One reason for this change is that the general public is better educated about the dangers of these two conditions. Also, warmer clothing and footwear are generally available.

The one group of people among whom frostbite and frostnip has increased are the homeless. Homeless people often have no place to go when the temperature drops. The growing popularity of outdoor sports has also increased the number of people at risk for frostbite and frostnip.
