Abstract
As a basis for clarifying the influence of low humidity on drying of skin, the distribution of vapor resistance of
horny layer was determined from the literature values of the thickness of horny layer for each segment of body surface. Under
the assumption that the resistance is proportional to the thickness of horny layer, using the prevailing values as the average of
whole body, the resistances for hands and feet were determined to be larger and those for the other parts smaller. In addition,
the influence of air velocity and vapor resistance of clothing on the total resistance between the saturated point under the horny
layer and room air was analyzed. As the results, the influence of air velocity less than 1m/s and that of clothing less than 1clo
were not significant on the total resistance. However, it was suggested that for the body part whose vapor resistance of horny
layer is smaller than the average, the influence of clothing resistance might not be negligible for the evaluation of skin drying
due to the evaporation to the ambient air.
