This paper deals with the characteristics of wettedness under constant average skin temper-ature and its effect on the equal skin temperature lines. From the basic measurements of both environmental parameters and human physiological responses, the following results were obtained : Under the condition of constant activity level, clothing worn, air movement and constant average skin temperature, 1. there is a positive correlation between the wettedness and the environmental humidity. 2. there is a negative correlation between the wettedness and the air temperature. 3. there is a negative correlation between the wettedness and the evaporative heat loss. 4. both the maximum and the minimum wettedness values corresponding to each average skin temperature exist. The theoretical examinations regarding the above-mentioned items the characteristics of wettedness under the constant average skin temperature were extended, and we finally obtained the following ; the locus of equal skin temperature is not a straight one but a curve on the psychrometric chart.
