热舒适性，自我报告的急性健康症状，认知能力和生理反应进行了检查，在四个温度（26，30，33和37摄氏度），相对湿度为70%。32名亚热带适应的受试者在气候室中以平衡的顺序经历了每种条件175分钟。热的感觉随着温度的升高而逐渐增加，但受试者只在37摄氏度时感觉到热。33摄氏度的温度平均被评为可接受的，只是不舒服。空气质量的可接受性随温度的升高而线性下降。受试者报告的急性健康症状强度随温度升高而增加，但即使在最高温度下也不超过中度;皮肤和眼睛干燥减轻。鼓膜温度、皮肤温度和湿度、心率、潮气末二氧化碳和体重减轻随温度升高而显著增加，而相邻心搏间期差异>50 ms的百分比显著降低。这些结果表明，感知的热量，自我报告的症状，和生理反应同时发生。他们还表明，对热的适应可能会将热不适的边界转移到更高的温度。心理适应的作用和这一过程的背景方面仍然需要澄清在未来的实验。
Thermal comfort, self-reported acute health symptoms, cognitive performance, and physiological reactions were examined at four temperatures (26, 30, 33, and 37 degrees C) at a relative humidity of 70%. Thirty-two sub-tropically acclimatized subjects experienced each condition for 175 minute, in balanced order, in a climatic chamber. The perception of heat gradually increased with increasing temperature, but the subjects felt hot only at 37 degrees C. The temperature of 33 degrees C was on average rated as acceptable and only just uncomfortable. The acceptability of air quality decreased linearly with increasing temperature. The intensity of acute health symptoms reported by the subjects increased with increasing temperature, but it was no more than moderate even at the highest temperature; dryness of skin and eye were alleviated. The eardrum temperature, skin temperature and moisture, heart rate, end-tidal carbon dioxide, and weight loss increased significantly with increasing temperature, whereas the percentage of adjacent heart inter-beat intervals differing by >50 ms decreased significantly. These results suggest that the perceived heat, self-reported symptoms, and physiological reactions occurred concurrently. They show additionally that acclimatization to heat may shift the boundary of thermal discomfort to a higher temperature. The role of psychological adaptation and of the contextual aspects of this process still requires clarification in future experiments.
