Thermal Resistance of the Cheek in Cold Air

摘要

Some experiments were carried out to characterize the thermal resistance of thetissues of the cheek area. Heat flow and skin temperature in cold air were measured with a heat-flux transducer. The face was cold when the cheek skin temperature was below 15 C and painful when the skin temperature fell below 10 C. Thermal resistance 2 increased as skin temperature fell, reaching a maximum of 0.07 M K/W at a skin temperature between 10 C and 15 C.
