由于睡眠不足和昼夜节律因素导致的困倦会对表现产生不利影响，并导致道路和工作场所事故。在夜班期间或夜班前小睡一会儿，可以缓解工作时和下班后路上的困倦。这项研究调查了在实际夜班之前或期间小睡30分钟的影响。性能进行了评估，在三个重复的措施，交叉条件;午睡前夜班（20：15小时），午睡在夜班（04：00小时），没有午睡。八名健康的夜班工人完成了模拟驾驶任务，精神警觉任务和卡罗林斯卡嗜睡量表在开始，结束时，并在一个实际的夜班。在夜班结束时，在任何午睡条件下都没有观察到性能的显着改善。30分钟的小睡机会不足以克服第一次夜班期间睡眠不足和昼夜节律影响对表现的有害影响，之前没有白天睡眠。
Sleepiness due to sleep loss and circadian factors can have a detrimental effect on performance, and contribute to road and workplace accidents. A brief nap taken during or immediately before a night shift may alleviate sleepiness both at work and on the road after work. This study investigated the effects of a 30-minute napping opportunity before or during an actual night shift. Performance was evaluated in three repeated-measures, crossover conditions; a nap prior to night shift (20:15 h), a nap during night shift (04:00 h) and no nap. Eight healthy nightshift workers completed a simulated driving task, the Psychomotor Vigilance Task and the Karolinska Sleepiness Scale at the start, end, and during an actual night shift. No significant improvement in performance was observed at the end of the night shift in either nap condition. A 30-minute napping opportunity was not sufficient to overcome the deleterious effects of sleep loss and circadian effects on performance during a first night shift, with no prior daytime sleep.
