The present paper is aimed at determining whether the dressing behavior for temperature regulation in cold is under the influences of circadian control. The half-naked subjects were instructed to dress in the garments they felt comfortable when the room temperature began to decrease from 30 degrees C to 15 degrees C in 1 h. To determine the effects of brain temperature fall on the dressing behavior, we used face cooling with cool air for 30 min before the room temperature began to decrease. We also studied the effects of wearing a hat on dressing behavior. Rectal temperature, tympanic temperature, skin temperature at seven sites, and thermal sensation were recorded. Major findings are summarized as follows: 1) the subjects dressed faster with thicker clothing in the morning than in the evening; 2) the subjects with face cooling dressed faster with thicker clothing than the subjects without face cooling; 3) the subjects without a hat dressed more rapidly with thicker, heavier clothing. These results were discussed in terms of load error between actual and set-point values in the core temperature.
本文旨在确定寒冷环境下用于体温调节的着装行为是否受昼夜节律控制的影响。当室温在1小时内从30摄氏度降至15摄氏度时，指导半裸的受试者穿上他们感觉舒适的衣物。为了确定脑部温度下降对着装行为的影响，我们在室温开始下降前，用冷空气对面部进行30分钟的冷却。我们还研究了戴帽子对着装行为的影响。记录直肠温度、鼓膜温度、七个部位的皮肤温度和热感觉。主要研究结果总结如下：1）受试者在早晨比晚上穿得更快且衣服更厚；2）面部冷却的受试者比未进行面部冷却的受试者穿得更快且衣服更厚；3）不戴帽子的受试者穿着更厚、更重的衣服时着装速度更快。根据核心温度实际值与设定值之间的负荷误差对这些结果进行了讨论。
