Effects of fluctuating thermal environment on human body during sleep

为了从更好的睡眠或舒适感的角度获得设计安全舒适的居住环境的基础数据和知识，进行了各种研究。通过改变人工气候室内温度的实验，研究了睡眠过程中时间变化或瞬态对人体的影响。对已经建立的用于评价清醒期热环境的人体体温调节模型进行了修正，使其能够用于评价和模拟睡眠期人体的热环境。此外，在实际居住的房屋中，季节性气候和热水浴或房屋装修的干预操作，影响睡眠质量的占用老年人进行了调查。

In order to obtain the basic data and knowledge to design the safety and comfortable dwelling environments from the views of better sleep or comfortable sensation, a variety of research was carried out. The experiments which change the temperature in the climatic chambers were performed to investigate the effects of time variability or transient on the human body during the sleep. The human thermoregulatory model which had already developed to evaluate the thermal environment in the awaking period was also tried to revise to evaluate and simulate the sleeping human body. Moreover, in the actual living houses both the seasonal climate and the intervention operations of hot bathing or housing renovation were investigated to influence the sleep quality of the occupied elderly persons.
