体温のサーカディアンリズムを考慮した夏期の睡眠時の温熱環境条件の評価

抄録

The effect of dynamic control of ambient temperature (T_a) and relative humidity on sleep quality during nocturnal sleep in summer was evaluated from psychological and physiological responses. Four healthy male subjects volunteered for the experiments in August 2007-2008. By comparing with the constant 28℃/60% condition, six dynamically controlled thermal conditions were tested. The EEG, body core temperature (T_<cr>) and subjective evaluation on sleep were recorded. The results demonstrated that a gradual increase of T_a from 26℃ at the beginning of sleep to 28℃ until awaking may be the best for ensuring sleep quality as well as circadian rhythm of T_<cr>.
