Abstract

By using slow linear thermal transients (+/- 0.025 degree C/min) of reduced amplitude (+/- 3 degrees C around thermoneutrality), we were able to advance the minimum of human internal temperature (Ti) during nocturnal sleep. During experimental night the minimum of esophageal (Tes) and rectal (Tre) temperature were respectively advanced by 1.6 h (P < 0.01) and 2.6 h (P < 0.001) in comparison to reference night spent at thermoneutrality. It must be emphasized that the provoked advance of nocturnal Ti minimum was not accompanied by any change in sleep latency, efficiency, SWS and REM sleep percentages. The result shows that appropriate ambient temperature transient changes could be used to modify the course of human Ti one of the major biological rhythms usually considered as resistant to sleep-wake rhythm manipulation.

摘要

通过使用幅度减小（在热中性附近±3摄氏度）的缓慢线性热瞬变（±0.025摄氏度/分钟），我们能够在夜间睡眠期间提前人类内部体温（Ti）的最低点。在实验夜间，与在热中性条件下度过的参考夜间相比，食管温度（Tes）和直肠温度（Tre）的最低点分别提前了1.6小时（P < 0.01）和2.6小时（P < 0.001）。必须强调的是，夜间Ti最低点的诱发提前并未伴随睡眠潜伏期、效率、慢波睡眠和快速眼动睡眠百分比的任何变化。结果表明，适当的环境温度瞬变可用于改变人类Ti的进程，Ti是通常被认为对睡眠-觉醒节律操纵具有抗性的主要生物节律之一。
