When living tissue freezes, the effect is called frostbite , which can happen any time the air temperature dips below 32°F. Your skin has a layer of insulating air around it, and when wind disturbs that insulating layer, it can hasten the loss of heat and cause your skin to freeze. (popsci.com)
But there are ways to protect yourself against wind chill and frostbite. (popsci.com)
For the first time, the new Wind Chill Chart includes a frostbite indicator, showing the points where temperature, wind speed and exposure time will produce frostbite on humans. (vtvast.org)
Frostbite, the most common type of freezing injury, is defined as the freezing and crystalizing of fluids in the interstitial and cellular spaces as a consequence of prolonged exposure to freezing temperatures. (medscape.com)
The fingers, toes, ears, and nose-the skin structures most at risk for frostbite-contain multiple arteriovenous anastomoses that allow shunting of blood in order to preserve core temperature at the expense of peripheral tissue circulation. (medscape.com)
Wind chill and frostbite. (cdc.gov)
From a public health standpoint, the reason for having a Wind Chill Temperature Index is to be able to advise people when they are at risk for frostbite. (cdc.gov)
The risk of frostbite increases as temperature decreases and wind speed increases, because more and more heat is lost from the skin. (cdc.gov)
According to the National Weather Service and NOAA, the new wind chill temperature index greatly improves the accuracy of the frostbite threshold, the temperature at which your skin freezes. (cdc.gov)
