How dangerous is wind chill?

Wind chill is an index measuring how cold it feels when wind is added to the current air temperature.
For example if the air temperature is 10 degree with no wind it will feel like it is 10 degrees. However if you add a 15 mile per hour wind the air temperature will feel like it is -7 degrees.
The reason for this change is as wind moves across your body it draws away the heat your body causing you to become colder. As the air temperature decreases and the wind speed increases the wind chill value will be higher....
meaning that you are in greater danger of being hurt or killed and the higher the wind chill the faster the cold will hurt you. If the wind chill is -20 degrees it will take less than 30 minutes for your skin to freeze, resulting in frostbite. ...
Frostbite is nothing to ignore as the damage it causes can range from minor irritation to frozen skin such as fingers, ears and nose which may need to be surgically removed. The lesson to take from this is when it is really cold and windy, don’t go outside....
If you must go outside, then wear gloves, hats, scarfs and jackets to cover exposed skin. <end>
