The methodology to describe the individual difference in temperature regulation of human body intransient state is proposed in this paper. In order to clarify the individual difference experimentally, thechange in skin and core temperatures was measured for four subjects exposed to a thermal transientcondition including stepwise air temperature change of coming and going to lower and highertemperature condition from thermally neutral condition. The differences in core temperature andregulatory responses were found to be significant. At the same time, for each subject who participatedin the experiments, the physiological parameters in two-node model were determined by using theexperimental data and a numerical optimization program. With the use of the determined combinationof parameters, the calculated results agreed well with the experimental results both for skin and coretemperatures for all four subjects. The experimental results in another case of transient state wereanalyzed and they coincided well with the calculated results obtained with using the above determinedparameters. Therefore it was shown that the combination of the parameters determined in this paperdescribe the characteristics in dynamic thermoregulatory responses of each subject.
