研究目的是弥补缺乏直接比较夜间睡眠限制后短时间和长时间小睡的影响的实验研究。设计12名年轻的成年健康睡眠者参加了一项重复测量设计，比较了不午睡、10分钟午睡和30分钟午睡的效果，每种情况下的总睡眠时间为4.7小时。分别在小睡结束前、小睡结束后5分钟、35分钟和60分钟进行客观和主观警觉性测量和认知操作测量。设置N/A参与者N/A干预N/A测量和无午睡条件测量结果显示，在整个测试期间，警觉性和表现要么没有变化，要么有所下降。在小睡10分钟后，主观警觉性和认知表现立即得到改善，这一点在小睡后一小时的测试中保持不变。小睡30分钟后，大多数警觉性和表现指标立即下降，但在测试结束时显示出一些恢复。结论：由于30分钟午睡后的延迟益处可能是由于睡眠惰性所致，因此应该调查较长的午睡后测试期。然而，我们得出的结论是，至少在午睡后的一个小时内，通过午睡10分钟，睡眠限制的有害影响得到了更快、更显著的改善。
STUDY OBJECTIVES The purpose was to remedy the lack of experimental studies directly comparing the effects of brief and long daytime naps following nocturnal sleep restriction. DESIGN Twelve young adult healthy sleepers participated in a repeated measures design comparing the effects of no nap, a 10-minute nap, and a 30-minute afternoon nap in each case following a night of 4.7 hours of total sleep time. Objective and subjective alertness measures and cognitive performance measures were taken before, then 5, 35, and 60 minutes after the termination of the nap. SETTING N/A. PARTICIPANTS N/A. INTERVENTIONS N/A. MEASUREMENTS AND RESULTS In the no nap condition measures showed either no change or a decreases of alertness and performance across the testing period. Following the 10-minute nap there was an immediate improvement in subjective alertness and cognitive performance which was sustained for the hour of post nap testing. Immediately following the 30 minute nap most measures of alertness and performance declined but showed some recovery by the end of testing. CONCLUSIONS Because the delayed benefits following the 30-minute nap may be due to sleep inertia, longer post-nap testing periods should be investigated. However, we conclude that the detrimental effects of sleep restriction were more rapidly and significantly ameliorated, at least within the hour following the nap, by a 10-minute afternoon nap.
