Low humidity causes evaporation from the skin, making you feel colder than you would in a home with higher humidity. Did you know your tears can evaporate; thus, affecting your eye health?
On a side note dry air also damages wood flooring, artwork, plaster, and antiques. Most of the things in our homes require a minimum percent of moisture to be healthy or stable. Have you noticed how your floors will creak more in the winter? Also, the static builds up in low humidity levels and can damage costly micro-electronics found in our TVs, stereos, laptops and appliances.
