To acquire basic knowledge about local cooling and thus achieve energy saving and comfortable clothing design, we measured the thermal sensation, mean skin temperature, and tympanic temperature under various local cooling temperatures between groups of varying subjective thermal sensitivity and investigated the effect of cooling temperature and subjective thermal sensitivity on the psychological and physiological response in local cooling. The results obtained were summarized as follows: The scores for general thermal sensation were close to a thermally neutral environment and the mean skin temperature decreased and the tympanic temperature increased with decreasing cooling temperature in a hot environment. The thermal sensation at the local cooling parts tended to change from a sensation of warmth form one of cold with decreasing cooling temperature. The general thermal sensation of the group with nonsusceptibility to heat was close to a thermal neutral environment with decreasing cooling temperature, while that of the group with susceptibility to heat remained almost constant. The pattern of tympanic temperature, however, was opposite to the general thermal sensation. The thermal sensation, skin temperature at the local cooling parts and the mean skin temperature were mainly affected by cooling temperature rather than the thermal sensation.
