Study on the gender difference in human thermal response under cold and hot impulses in winter
In order to explore the gender difference in human thermal response under cold and hot impulses,this study conducted cold and hot impulses experiments on 8 male and 8 fe-male subjects with different temperature differences,and obtained the mean skin tempera-ture(Tmean),heart rate(HR),thermal sensation vote(TSV)and thermal comfort vote(TCV)of the subjects.The changes of parameters before and after the impulse were calcu-lated to reflect the influence of different temperature differences on human body,and the changes in Tmean,HR,TSV and TCV of males and females before and after the impulse were analyzed under different temperature differences,namely ΔTmean,Δx HR,ΔxTSV and ΔxTCV.The results shown that the ΔTmean and the ΔxTSV in both males and females were positively correlated with the temperature difference of the impulse under impulse conditions.The gen-der difference was more significant with the increase of impulse temperature difference,es-pecially under the impulse temperature differences of 15 and 18 ℃.The ΔxTCV of males shown an inverted U-shaped change with the increase of impulse temperature difference.At the same time,it was found that female's thermal regulation ability was weaker than male's,which was manifested as their|ΔTmean|,|ΔxTSV|and|ΔxTCV|were usually larger than that of males under impulse working conditions.
