The aim of this study was to investigate any effects of electric blanket on sleep stages and body temperature. Nine male subjects slept under two conditions: using the electric blanket (HB); and not using the electric blanket (C). The ambient condition was controlled at 3 degrees C relative humidity 50-80%. Electroencephalography, electrooculography (EOG) and electromyography, rectal temperature, skin temperature and microclimate temperature and humidity were recorded continuously through the night. Body weight was measured before and after sleep. The amount of stage 1 and number of stage 1 and rapid eye movement sleep decreased in HB compared to C. No significant difference was observed in other sleep stages. Rectal temperature was higher in HB compared to C. The thigh, leg and foot skin temperature was higher in HB than C. The microclimate temperature of the foot area was higher in HB compared to C. No significant difference was observed in whole body sweat loss between the conditions. These results suggest that use of an electric blanket under low ambient temperature may decrease cold stress to support sleep stability and thermoregulation during sleep.
本研究的目的是调查电热毯对睡眠阶段和体温的任何影响。九名男性受试者在两种条件下睡眠：使用电热毯（HB）；不使用电热毯（C）。环境条件控制在3摄氏度，相对湿度50 - 80%。整夜连续记录脑电图、眼电图（EOG）和肌电图、直肠温度、皮肤温度以及微气候温度和湿度。在睡眠前后测量体重。与C组相比，HB组的1期睡眠量以及1期和快速眼动睡眠的次数减少。在其他睡眠阶段未观察到显著差异。与C组相比，HB组的直肠温度更高。HB组大腿、腿部和足部的皮肤温度高于C组。与C组相比，HB组足部区域的微气候温度更高。在这两种条件下，全身出汗量未观察到显著差异。这些结果表明，在低环境温度下使用电热毯可能会降低冷应激，以支持睡眠稳定性和睡眠期间的体温调节。
