Abstract

In order to quantify the accumulative effect of continuous high temperature weather on the physiological stress of human body, a field experiment was conducted with ten healthy college students being selected as subjects and three consecutive days of which the was larger than 35℃ were maximum outdoor temperature considered as continuous high temperature condition, meanwhile the physiological parameters of the subjects under non air-conditioned indoor environment were also measured. Then the changes in these parameters within the three days were analyzed through paired T-test to verify the presence of accumulative effect. Finally, the daily maximum temperatures of the three days were corrected by utilizing the temperature correction model and thus the cumulative effect was quantified. The results indicate that the continuous high temperature exerts an unfavorable accumulative effect on systolic blood pressure, rectal temperature and mean skin temperature, and the cumulative effect coefficient of the second day on the third day is larger than that of the first day on the third one, the ranking of the coefficients goes as mean skin temperature > systolic blood pressure > rectal temperature. © 2021 China Safety Science Journal
