Wind chill accounts for the loss of body heat by replacing the layer of warm air surrounding your body with a layer of colder air. If the air were not moving (i.e. no wind), the layer of warm air produced by your body would act as an insulator. When that insulation layer is blown away, your body is constantly warming this colder layer of air. This constant loss of body heat causes the temperature to feel colder than the thermometer indicates.

Visitors to Utah should take this process into account when dressing for various events and activities. Proper dress can help protect against hypothermia and other exposure-related injuries. See the Winter Dress page for more information.
