严重的主观和生理性嗜睡发生在夜间工作中，几乎折磨所有的人，并与严重到足以解释夜间工作事故数据的表现障碍有关。警觉性不足是由于工作转移到最不利于警觉行为的昼夜节律阶段，通过延长清醒时间和减少睡眠时间（由于昼夜节律干扰睡眠）造成的。当这三个原因同时起作用时，嗜睡将是极端的。这三个因素可以用来定量预测嗜睡。
Severe subjective and physiological sleepiness occur in night work, afflict almost all individuals and are associated with a performance impairment severe enough to explain night-work accident data. The alertness deficit is caused by the displacement of work to the circadian phase which is least conducive to alert behaviour, by extension of the time spent awake and by the reduction of sleep length (due to circadian interference with sleep). Sleepiness will be extreme when the three causes are operative simultaneously. The three factors may be used quantitatively to predict sleepiness.
