Wind chill is another variable to consider during this time of year. How cold the wind makes us feel is called wind chill. Wind chill is an estimate of the wind's cooling power and its ability to remove heat from the body, replacing it with colder air. Once the wind starts to blow, the insulating layer of warm air next to the skin is swept away, and heat is rapidly removed from the body. The faster the wind blows, the greater the heat loss and the colder we feel.
Wind chill is only an estimate of discomfort because other factors determine actual discomfort.
For example, the amount of sunlight, the relative humidity and the mode of dress. Strangely enough, the colder people become, the warmer they begin to feel. Individuals who die as a result of exposure often begin taking off their clothes during the last moments of life. Proper dress for cold, wintry weather is critical. Dress in layers.
