Dangers of wind chill, extreme cold
Beware hypothermia and frostbite when temperatures dip
Last Updated: Jan. 2, 2014
Exposure to winter's bitter cold brings serious health risks. These become even more severe when the wind blows, because it cools our skin temperature and makes us feel colder. Read more about the science of wind chill.
The colder it feels, the more pronounced the danger. As Environment Canada's guidelines illustrate, just a few minutes outside can lead to hypothermia (dangerously lowered body temperature) and frostbite (frozen skin) when wind-chill values become extreme.
