In recent years, heat stroke due to thermal load on the human body has become a serious issue. The effects of thermal load on the human body are deeply related not only to external factors but also to internal factors such as physical condition and state of activities. In order to investigate the state of seasonal acclimatization of the human body during the hot season, we conducted an experiment in which subjects rested in a standing position in a hot environment before and after seasonal acclimatization. The subjects were exposed to a hot environment in a climate chamber room. During the hot period, there was a decrease in core temperature and metabolic rate, and an increase in perspiration in some subjects, but the differences were not significant, and the correlation between metabolic rate and core temperature was also not significant and clear relationship between them was not found. Meteorological data suggested that heat acclimatization in this year was formed in June July temporarily resolved to some extent in mid-August.
