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.

主要结果如下：1使用电热毯后，夜间直肠温度明显高于不使用电热毯时。在有电热毯和无电热毯两种情况下，几个部位计算的平均皮肤温度几乎相同。床上气候（温度、湿度）也相同。因此，我们认为，在两种情况下，夜间睡眠时直肠温度的不同程度应该是由于热因素以外的其他因素造成的夜间睡眠时尿中褪黑激素的代谢物在电热毯组中较低。这可能与夜间直肠温度升高有关对电热毯使用过程中的电磁场进行了定量测量。
