RELATIVE HUMIDITY
The American Society of Heating, Refrigeration, and Air-Conditioning Engineers (ASHRAE) recommends indoor air be tempered to within the following parameters:

RELATIVE HUMIDITYWINTER TEMPERATURESUMMER TEMPERATURE
30%68.5 - 76 °F74 - 80 °F
40%68.5 - 75.5 °F73.5 - 79.5 °F
50%68.5 - 74.5 °F73 - 79 °F
60%68 - 74 °F72.5 - 78 °F

Low humidity has been associated with dry skin and eyes and with respiratory irritation.
