The occurrence of heat stress in healthy individuals is different from those with chronic diseases like diabetes. While exposed to heat, complications caused by diabetes may lead to problems in body temperature regulation. Due to the fact that diabetic workers are less efficient in hot environments, researchers are encouraged to evaluate this condition.
The current study incorporates 30 young males. In the first stage, individuals with the history of type 2 diabetes mellitus (T2DM), who frequently had exposure to heat at work, were selected and compared with non-diabetic workers as the control group. Indicators like deep body temperature, skin temperature, heart rate, physiological strain index (PSI), and perceptual strain index (PeSI) were measured and recorded. Eventually, data were evaluated and analyzed using repeated-measure design, independent test, and its nonparametric equivalent, The Mann-Whitney U test.
In the two groups of type 2 diabetes and control group, following one hour of heat exposure, the median heart rate was 115 (18) and 99 (21) ( = 0.008), respectively, mean deep body temperature was 37.6 (0.37) and 36.95 (0.41) ( < 0.001), mean PSI was 3.01 (0.93) and 2.08 (1.0) ( = 0.021), and mean PeSI was 7.82 (1.43) and 6.12 (2.14) ( = 0.032), which were significantly different. In addition, no significant difference was observed between the skin temperatures of the two groups after one hour of exposure to heat.
According to the results, workers with type 2 diabetes are exposed to more heat strain than the control group in the same hot environment.
健康个体中热应激的发生情况与糖尿病等慢性疾病患者不同。在受热时，糖尿病引发的并发症可能导致体温调节出现问题。鉴于糖尿病患者在炎热环境中工作效率较低，鼓励研究人员对这种情况进行评估。
本研究纳入30名年轻男性。在第一阶段，选择有2型糖尿病（T2DM）病史且经常在工作中受热的个体，并与非糖尿病工作者作为对照组进行比较。测量并记录深部体温、皮肤温度、心率、生理应激指数（PSI）和感知应激指数（PeSI）等指标。最终，使用重复测量设计、独立样本t检验及其非参数等价检验（曼-惠特尼U检验）对数据进行评估和分析。
在2型糖尿病组和对照组中，受热1小时后，两组的中位数心率分别为115（18）和99（21）（P = 0.008），平均深部体温分别为37.6（0.37）和36.95（0.4）（P < 0.001），平均PSI分别为3.01（0.93）和2.08（1.0）（P = 0.021），平均PeSI分别为7.82（1.43）和6.12（2.14）（P = 0.032），差异均有统计学意义。此外，受热1小时后两组的皮肤温度无显著差异。
根据结果，在相同炎热环境中，2型糖尿病工作者比对照组承受更多的热应激。
