70 degree air can hold more than 12 times as much moisture as 10 degree air. Outside air at 10 degrees and 70 percent relative humidity drops to 7 percent relative humidity when heated to normal room temperature without other internal sources of moisture, such as cooking, laundry, showers, etc. That is only a fraction of the humidity recommended for the average heated home, and it's this 'desert dryness' that makes you feel uncomfortable and takes moisture from your home, furnishings - even you and your family. Doctors often times have mentioned dry air as one of the causes for nose, throat, and other physical ailments. Heated air dries out and shrinks wood framing around the doors and window frames.
Gaps occur, permitting cold outside air infiltration.
