先前的现场和实验室研究表明，主观嗜睡存在昼夜变化，其形式与客观嗜睡和许多性能效率的测量不同。最差的主观嗜睡发生在昼夜温度节律的低谷，最少的主观嗜睡约7小时前的温度峰值。一系列强制去同步化实验，其中控制温度节律的内源性昼夜节律振荡器在睡眠/觉醒周期的不同时期运行，揭示了这些发现可以通过假设主观嗜睡受两个因素的控制来解释，最小的困倦发生在温度周期中的温度峰值和睡眠/觉醒周期中的觉醒后约6小时。
Previous field and laboratory studies have revealed that there is a diurnal variation in subjective sleepiness that is different in form to that of objective sleepiness and many measures of performance efficiency. The worst subjective sleepiness occurs at the trough in the circadian temperature rhythm, the least subjective sleepiness about 7 h before the peak in temperature. A series of forced de synchronization experiments, in which the endogenous circadian oscillator controlling the temperature rhythm ran at a different period to the sleep/wake cycle, revealed that these findings can be explained by postulating subjective sleepiness to be under the control of both factors, with minimum sleepiness occurring at the peak in temperature in terms of the temperature cycle and about 6 h after waking in terms of the sleep/wake cycle.
