Human Perception, of Humidity Under Four Controlled Conditions

The decrease and rise in RH did cause highly significant changes in the subjective sensation of temperature although this factor was held constant throughout.

Abstract

We have studied the subjective perception of humidity and temperature in 48 young male subjects exposed to clean air at 23 C with a relative humidity CRH) of 70%, 50%, 30%, and 10%. We observed no change in the perception of humidity on lowering it from 70% to either 50%, 30%, or 10%, nor on returning it to the initial level of 70%. The decrease and rise in RH did cause highly significant changes in the subjective sensation of temperature although this factor was held constant throughout.
