As you’ve seen, windchill can make a big difference in the temperature you feel during the cold. But how does it work? As winds blow and cold air comes into contact with your skin, heat is lost. This heat loss is caused by conduction, the transfer of heat through direct contact. Because your body is losing heat faster than it would with no wind, it feels colder than it really is. Exposed skin loses heat first followed by the rest of your body. If your body temperature gets too low, you could experience frostbite or hypothermia. Hypothermia is a decrease in body temperature from the normal 98.6°F to less than 95°F. It can cause shivering, confusion, low energy and loss of coordination. Frostbite is when body tissue actually freezes. The most likely body parts to get frostbite are fingers, nose, ears and toes.
