无论热环境如何变化，人体核心体温都保持准恒定。众所周知，生理性体温调节系统受对热能敏感的中枢和外周感觉器官的控制。如果这些系统错误地对非热刺激做出反应，可能会扰乱人体的稳态。15名参与者观看了在热恒定环境中唤起热或冷印象的视频图像。实验期间记录心血管指标。计算“冷热”印象评分与心血管指标之间的相关性。心率、心输出量和总外周阻力的变化与“冷热”印象评分显著相关，其变化趋势与实际热环境中相应印象的变化趋势相似。目前的研究结果表明，没有任何热能的视觉信息可以影响生理温度调节系统至少在表面上。为了避免这种“虚拟”环境干扰人体内稳态，需要进一步的研究和更多的关注。
Human core body temperature is kept quasi-constant regardless of varying thermal environments. It is well known that physiological thermoregulatory systems are under the control of central and peripheral sensory organs that are sensitive to thermal energy. If these systems wrongly respond to non-thermal stimuli, it may disturb human homeostasis. Fifteen participants viewed video images evoking hot or cold impressions in a thermally constant environment. Cardiovascular indices were recorded during the experiments. Correlations between the ‘hot-cold’ impression scores and cardiovascular indices were calculated. The changes of heart rate, cardiac output, and total peripheral resistance were significantly correlated with the ‘hot-cold’ impression scores, and the tendencies were similar to those in actual thermal environments corresponding to the impressions. The present results suggest that visual information without any thermal energy can affect physiological thermoregulatory systems at least superficially. To avoid such ‘virtual’ environments disturbing human homeostasis, further study and more attention are needed.
