Dry and cracked lips
Posted at 6:45 AM on November 20, 2008
by Craig Edwards
It's that time of year when temperatures fall into single digits and dew points can dip below zero. Throw in some sunshine and brisk winds and you have some very dry conditions.
Take that air indoors. Heat it up and you have indoor relative humidity that is desert like.
Ideally, you should try to maintain a healthy indoor humidity of about 35 percent when the outside air is greater than 20 degrees. In the depth of bitter cold, well below zero, a humidifier should be used to keep the indoor humidity around 20 percent. Relative humidity gauges are available at local hardware stores.
