Estimation of bedding comfort from the viewpoint of thermal and endocrine physiology

主要研究结果如下：1使用电热毯时夜间直肠温度明显高于不使用电热毯时。从几个网站计算的平均皮肤温度是几乎相同的两个条件之间的电热毯和没有电热毯。床的气候（温度、湿度）也是相同的。因此，我们推测，直肠温度在夜间睡眠期间的不同水平之间的两个条件应该是由于其他因素，除了热的。2尿褪黑激素在夜间睡眠期间低于在电热毯比没有。这可能与夜间直肠温度较高有关。3.定量测量了使用电热毯时的电磁场。

The main results are summarized as follows :1 Rectal temperature during night sleep was clearly kept highr with the usage of electrical blanket than otherwise. Mean skin temperature calculated from several sites was nearly identical between two conditions of electrical blanket and no electrical blanket. Bed climate (temperature, humidity) was also same. Therefore, we presume that different level of rectal temperature during night sleep between two conditions should be due to other factors except for thermal ones.2 Metabolites of urinary melatonin during night sleep were lower in electrical blanket than otherwise. These might be related with higher rectal temperature during the night nighttime.3 Electrical magnetic field was measured quantitatively during the usage of electrical blanket.
