Retrospective analysis of data collected over 15 years in normal subjects isolated from time cures showed seasonal rhythms in the circadian period of the core temperature rhythm, in the amount of sleep (both shorter in spring and longer in autumn), and in the incidence of internal desynchronisation (most often in summer). Women slept longer than men at all times of year.
对从时间疗法中分离出的正常受试者15年收集的数据进行回顾性分析,结果显示,核心体温节律的昼夜周期、睡眠时长(春季较短,秋季较长)以及内源性节律失调的发生率(最常发生在夏季)均存在季节性节律。一年中任何时候女性的睡眠时间都比男性长。
