Lennox Indoor Air Quality Systems

Why is my throat so dry?

During extremely cold weather, your home loses moisture to the outdoors, and the humidity level may drop to as low as 10 percent. A humidifier adds moisture to your indoor air and can help relieve ailments related to dry respiratory membranes.

One of the major causes of respiratory infections is inadequate humidity during cold weather. The start of the heating season each fall causes many people to begin having repeated attacks of winter colds. Winter weather is blamed for these problems, but the actual cause may be dryness, which develops in the membranes of the nose, throat and bronchial tubes. Relative humidity also has a significant effect on controlling the occurrence of airborne infections.
