「Effects of partial humid heat exposure during different segments of sleep on human sleep stages and body temperature」

The effects of timing of heat exposure on nocturnal sleep was investigated. Heat exposure during the 1st half of the night had severer impact on sleep and body temperature control than that during the 2nd half. (終夜の前半ないしは後半に暑熱負荷を加える条件で夜間睡眠を検討した。後半の暑熱負荷に比して、前半の暑熱負荷の方が睡眠構築および体温調節反応の両者共により負担が大きいことを示唆する結果が得られた。)
