For the study of such a complex biological system as a temperature regulation system in the human body, it is effective to proceed with both physiological experiments and theoretical analysis. This paper presents the physiological observations of thermal response of a group of clothed male subjects to a step change in ambient temperature compared with data of the nude subjects for considering the effect of clothing. The subject was made to be sitting in rest for an hour in the previous room which was kept at about 28℃ and 50% RH. After that, the subject was suddenly moved into the climate room of which the temperature was kept constant at 7, 13, 16, 19, 22, 25, 28, 31, 34, 37 or 43℃ respectively and the humidity was kept 50% RH. And the subject was made to be sitting in rest for about three hours. The observation was continued for those about four hours. The measureing terms were rectal and skin temperature, blood flow rate of the left forefinger by venous occlusion plethysmography which was adopted for an index of blood flow through the outer part in the mathematical model, decrease of the body weight, metabolic heat production, heart rate, respiration rate, heat flux through the skin, thermal sensation and thermal comfort. These observations were arranged as the steady state characteristics of the temperature regulation system in the human body, and the step responses of the skin temperature and others. These experimental results showed a good agreement with the theoretical results.
