The effects of skin coolingon the regional differences of thermoregulatory responses wearing a water-perfused suit ware studies. A women subject was kept in the rest supine posture in a climatic chamber of temperature of 30.0±0.5°C, relative humidity of 50±3% and air velocity of 0.2m/sec. The tests were repeated three times under the same experimental conditions. The temperature set at a suit was maintained at 33°C for 30 min., then lowered to 24°C by every 3°C for every 30mins. On torso, the change in thermal sensation at a given decreased skin temperature was greater, but the change in skin blood flow at a given dcreased skin temperature was smaller than that on extremities. These results suggest that the degree of variation in thermal sensitivity and in skin blood flow against lowering skin temperature were greatly different from the sites of trunk and extremities.
