该研究考察了午睡时间、午睡时间和睡眠质量如何影响清晨（6:00至8:00）的表现。12名学生参加了模拟夜班时间表（22:00至8:00），其中夜间小睡的时间和时间被控制（0:00-1:00,0:00-2:00,4:00-5:00和4:00-6:00）。性能测试包括精神运动警觉性测试、逻辑推理测试和主观疲劳和困倦的视觉模拟量表。结果显示，120分钟的午睡比60分钟的午睡更能维持清晨的表现。早睡或晚睡对神经行为测试没有影响，尽管参与者在夜班晚些时候睡得更有效率。在睡眠结构中没有观察到夜班期间夜间小睡对随后的白天和夜间睡眠的负面影响。目前尚不清楚慢波睡眠是否在维持清晨表现方面起着重要作用。就工作安全和睡眠健康而言，研究结果表明，在夜班期间，更长、更晚的午睡是有益的。
The study examined how nap length, nap timing and sleep quality affect early morning performance (6:00 to 8:00). Twelve students participated in a simulated nightshift schedule (22:00 to 8:00) where the length and timing of nocturnal naps were manipulated (0:00-1:00, 0:00-2:00, 4:00-5:00 and 4:00-6:00). A performance test battery was administered consisting of a psychomotor vigilance test, a logical reasoning test, and a visual analogue scale for subjective fatigue and sleepiness. The results showed that a 120-min nap sustained early morning performance better than a 60-min nap. Taking a nap earlier or later did not affect the neurobehavioral performance tests, although participants slept more efficiently during naps later in the night shift. A negative effect of a nocturnal nap during the night shift on subsequent daytime and nocturnal sleep was not observed in the sleep architecture. It still remains unclear whether slow wave sleep plays an important role in sustaining early morning performance. In terms of work safety and sleep health, the results suggest that a longer and later nap is beneficial during night shifts.
