Optimum Relative Humidity for Health

The Sterling Chart illustrates how RH affects health and well being.

Colds, flu, sore throat, dry eyes, itchy and cracked skin are all symptoms that are usually prevalent in the cold dry months of the winter when the indoor RH is at its lowest.

The increase in bacteria, viruses and ozone production (caused by static electricity) in low RH levels all have an adverse affect on health.
