Experiments consisting of baseline, bright light and physical exercise studies were carried out to compare the effect of a 9-hour delay in sleep-wakefulness timing, and the effects of bright light and physical exercise interventions on 24-hour patterns of performance, mood and body temperature were examined. Each study comprised a 24-hour constant routine at the beginning followed by 3 night shifts and 24-hour constant routine at the end. Performance on tasks differing in cognitive load, mood and body temperature was measured during each constant routine and the interventions were applied during the night shifts. The 24-hour pattern of alertness and performance on the tasks with low cognitive load in post-treatment conditions followed the change in sleep-wakefulness timing while more cognitively loaded tasks tended to show a reverse trend when compared to pre-treatment conditions. There was a phase delay around 4 hours in circadian rhythms of body temperature in post-treatment conditions.
进行了包括基线、强光和体育锻炼研究的实验，以比较睡眠-觉醒时间延迟9小时的影响，并研究强光和体育锻炼干预对24小时的表现、情绪和体温模式的影响。每项研究开始时都有一个24小时的固定程序，随后是3个夜班，最后又是一个24小时的固定程序。在每个固定程序期间测量不同认知负荷、情绪和体温任务的表现，并在夜班期间进行干预。与治疗前相比，治疗后低认知负荷任务的24小时警觉性和表现模式跟随睡眠-觉醒时间的变化，而认知负荷较高的任务则倾向于呈现相反趋势。治疗后体温的昼夜节律有大约4小时的相位延迟。
