![]() ![]() "This includes dressing warmly to avoid frostbite and hypothermia." "The wind chill index allows Canadians to learn the best ways to avoid injuries from the cold," Environment Canada and Climate Change says. If the air temperature is -10☌ and there’s a 15 km/h wind blowing-not uncommon on any winter day across Canada-the wind chill would make it feel like -17 to your body. They used those findings to create the wind chill, which tells us what temperature it really feels like on exposed skin when it’s both cold and windy. Scientists have spent decades studying how to best account for how gusty winds affect the human body in cold temperatures. LEARN MORE: Understanding the warning signs of frostbite The harder the wind blows, the more intensely that cold air rubs against our skin. When the wind blows, however, that tiny layer of insulation is stripped away, and the full force of the cold air presses directly against any exposed skin. ![]() Our body heat warms up the layer of air touching any exposed skin, which provides us with a little bit of insulation against the harsh chill. One of the many ways we stay warm when it’s chilly outside is through our own radiant heat. There are a number of hidden dangers lurking on a frigid winter’s day.Įxtreme cold takes a unique toll on the human body. RELATED: What is the polar vortex? How it’s responsible for dangerous cold Wind chill values give us a countdown to frozen injuries Wind on a cold day can cost you a finger-or worse. Every part of a meteorologist’s job-from tracking storms on radar to predicting tomorrow’s high temperature-is done with you and me in mind.Īnd everyday weather has no greater impact on our bodies than the simple combination of temperature, humidity, and wind. Meteorology is a study of humans as much as it is a study of the weather itself. A bitterly cold day can have a significant impact on our bodies that goes far beyond a simple number on the thermometer.
