Abstract

In this research, we investigated the quantitative effect of bathing on the heat loss of hot water in the bathtub and thermal storage of the human body through experiment and simulation using 65-Node thermoregulation-Model applied to bathing. In the experiment, three subjects took a bath four times, with temperatureoftheir tympanic membrane and hot water measured. It turned out that about 700-1200kJ of heat is lost from hot water in the bathtub and about 400-650kJofheat is charged in human body by twenty minutes bathing.
