Learn about the dangers of wind chill and how to stay safe.
What is wind chill?
When you hear your local meteorologist talk about wind chill, he or she is referring to how cold your skin feels when you are out in winter weather when the wind is factored in.Wind chill is a measurement of how quickly a person loses heat when it is cold. It's an equation that uses temperature and wind speed.You have a thin layer of warm air just above your skin. When you are in the cold and the wind starts to blow, that thin layer is stripped away.
Your body cuts circulation to your extremities when temperatures drop to critical levels to protect your internal organs. The lack of circulation leads to the death of the tissue. Hypothermia happens when your core body temperature drops. Your core body temperature is usually around 98.6 degrees Fahrenheit. If your core body temperature drops to below 95 degrees, you are considered “hypothermic,” or suffering from hypothermia.
If you are hypothermic, you are losing body heat. Normally, the heart and liver produce the majority of your body’s heat. But if your core body temperature is cooling because of exposure to cold weather, the activity of the heart and liver slow down to preserve heat and protect the brain. This can lead to organ shutdown and death as you get colder. This can happen rather quickly.
