人类在日常生活中经常会暴露在温度突变的环境中。例如，当从室外进入/离开空调建筑物时，人们不仅可能遭受热不适，而且甚至可能遭受一些潜在的健康问题。本研究以24名志愿者为实验对象，研究了不同气温阶跃变化（S5：32°C-37°C-32 °C，S11：26°C-37°C-26 °C，S15：22°C-37°C-22 °C）对人体健康和热舒适的影响。结果表明，出汗，眼疲劳，头晕，呼吸加速和心率是敏感的自我报告的症状，以响应温度阶跃变化。除了S15（22 °C-37 °C）升阶时的热舒适性和可接受性外，温度阶跃前的热感觉、舒适性和可接受性与阶跃变化后的热感觉、舒适性和可接受性有显著区别。当受试者从中性环境移动到温暖环境时，会出现滞后现象。心理引导既发生在上台阶之后，也发生在下台阶之后。温度阶跃的大小和变化方向对人体对温度阶跃的反应有显著影响。
Human beings are often likely to expose themselves to sudden temperature change in daily life. For example, when entering/exiting an air-conditioned building from/to outdoors people may suffer not only thermal discomfort but also even some potential health problems. In this study, the influence of different air temperature step-changes (S5:32°C-37°C-32 °C, S11:26°C-37°C-26 °C, and S15:22°C-37°C-22 °C) on human health and thermal comfort was studied with 24 volunteered participants in the laboratory experiment. Results show that perspiration, eyestrain, dizziness, accelerated respiration and heart rate are sensitive self-reported symptoms in response to temperature step-changes. Thermal sensation, comfort and acceptability just before temperature step are significantly distinguished from that immediately after step change except for thermal comfort and acceptability in up-step of S15 (22 °C-37 °C). Hysteresis phenomenon appears when subjects move from neutral to warm environment. Psychological lead occurs after both up-steps and down-steps. Temperature step magnitude and changing direction have significant impact on human response to temperature steps.
