Abstract
The subcutaneous fat explains to a large extent the individual differences, as well as the regional variations in the skin temperature, observed on the body. The insulation of the fat layer is 0.41 Clo per inch after one hour's exposure at 70° F., 1.18 at 60° F., and 1.96 at 50° F. The significance of these results, with reference to the thermal steady state of the body, is discussed.
