Napping is a cross-cultural phenomenon which occurs across the lifespan. People vary widely in the frequency with which they nap as well as the improvements in alertness and well-being experienced. The systematic study of daytime napping is important to understand the benefits in alertness and performance that may be accrued from napping. This review paper investigates factors that affect the benefits of napping such as duration and temporal placement of the nap. In addition, the influence of subject characteristics such as age and experience with napping is examined. The focus of the review is on benefits for healthy individuals with regular sleep/wake schedules rather than for people with sleep or medical disorders. The goal of the review is to summarize the type of performance improvements that result from napping, critique the existing studies, and make recommendations for future research.
小睡是一种跨越文化的现象，在人的一生中都会出现。人们小睡的频率以及所体验到的警觉性和幸福感的提升程度差异很大。对白天小睡进行系统研究，对于理解小睡可能带来的警觉性和表现方面的益处很重要。这篇综述论文调查了影响小睡益处的因素，如小睡的时长和时间安排。此外，还研究了年龄和小睡经验等个体特征的影响。综述的重点是有规律睡眠/清醒时间表的健康个体从小睡中获得的益处，而非有睡眠或医学疾病的人群。综述的目的是总结小睡带来的表现提升类型，对现有研究进行批判，并为未来研究提出建议。
