Abstract

While thermal environment have an effect for sleep, some previous studies reported there was little difference inquality of sleep in winter. This survey focused on the effects of changing thermal condition by air-conditioning onphysiological and psychological responses during nocturnal sleep in winter. Seven healthy female subjects volunteered for 8hours nocturnal sleep survey at own house. There were three conditions as control to daily habit (first night), two differentconditions using air-conditioning timer (2 hour off-timer after bedtime and 2 hour on-timer before arise time). We werecontinuously recorded bedside temperature, relative humidity and bed climate as thermal environments, skin temperature,core temperature, heart rate, body movement and so on as physiological responses during sleep. Subjective evaluations onsleep and environment were evaluated with thermal sensation vote, thermal comfort vote and OSA sleeping questionnaire.The results showed that 2hour off-timer influenced decreasing skin temperature, rectal temperature and heart rate onhypnagonic. When these physiological responses change over equilibrium, there were not different form conditions. Bedclimate affected thermal sensation and comfort vote more than using air-conditioning. OSA didn't have significance.
