Hot summer air usually has high humidity, and a person’s ability to throw off heat by evaporation decreases or stops altogether. Cooling is needed then to provide comfort by extracting excessive moisture from the air. During the winter, the condition is reversed. Cold outside air, heated to room temperature, has great ability to hold extra moisture. For example, air at 70F can hold about 20 times as much as air at 0F. Heated wintertime air takes moisture from whatever sources are available, including the human body. If the air in your home does not contain enough moisture, you may feel cold and uncomfortable – even at 75F.
