Abstract
Using tympanic temperature data during bathing measured in a laboratory thermal environment, the tympanic temperature during bathing was estimated for 120 people nationwide. There was a significant difference in the tympanic temperature change from the start of immersing bodies in the hot water, depending on the season. In particular, immediately after starting to immerse them in the hot water, it was influenced by the thermal environment during bathing. Furthermore, 86% of people left the hot water before the tympanic temperature change reached 0.5℃, while 13% of people continued to immerse themselves in the hot water even if their tympanic temperature had risen by more than 0.5℃. This trend was more common among those who engaged in hot bathing, during the autumn and winter seasons, and among individuals with a lean body type.
