Sleep deprivation (SD) is suggested to be associated with reduced thermo-regulatory functions. This study aimed to quantify the effect of partial (PSD) and total (TSD) 24 h SD using a standard heat tolerance test (HTT). Eleven participants underwent HTT after well-rested state, PSD and TSD. No significant physiological differences were found between the exposures but subjective discomfort was higher after TSD. Evening chronotypes' temperature during HTT was higher after TSD compared with PSD (p = 0.017). After TSD, evening chronotypes compared to intermediate chronotypes' temperature was higher during the first hour of the HTT (p < 0.05), suggesting that thermo-regulatory function during exercise in the heat is influenced by chronotype.
睡眠剥夺（SD）被认为与体温调节功能下降有关。本研究旨在通过标准耐热性测试（HTT）量化部分睡眠剥夺（PSD）和完全睡眠剥夺（TSD）24小时对其的影响。11名参与者在充分休息状态、PSD和TSD后接受了HTT。各暴露组之间未发现明显的生理差异，但TSD后主观不适感更高。与PSD相比，TSD后HTT期间夜型人的体温更高（p = 0.017）。TSD后，与中间型生物钟类型相比，夜型生物钟类型在HTT的第一个小时内体温更高（p < 0.05），这表明热环境中运动期间的体温调节功能受生物钟类型影响。
