午餐后嗜睡和表现恶化，或“午餐后蘸”，被认为是生物节律的一部分。短暂的小睡是一个很有希望的对策午餐后下降。与对小睡的影响的广泛研究相比，对相对较长的午睡（如下午60分钟或更长时间）的生理影响的研究有限。将43名睡眠-觉醒周期正常的男性大学生分为两组：第一组从0：00到6：00睡眠6 h，第二组从13：15到15：15小睡2 h。两组之间的主观睡眠质量没有显著差异。这一点得到了各组之间睡眠效率和潜伏期缺乏任何显着差异的支持。此外，午睡后的心率明显高于午睡前的基线水平（过冲），而早晨的心率与前一天晚上的心率相同。相对较长的午睡在睡眠质量方面可能与夜间睡眠相当，但它可能会在醒来后比早上增强更大的自主唤醒。© 2018日本电气工程师协会。由John Wiley & Sons公司出版
Post‐lunch sleepiness and deterioration in performance, or ‘post‐lunch dip’, is considered a part of the biological rhythm. A short nap is a promising countermeasure to the post‐lunch dip. Compared to the extensive studies on the effects of a short nap, there is limited research on the physiological impact of a relatively long nap such as 60 min or more in the afternoon. Forty‐three male university students with normal sleep–wake cycles were assigned to two groups: group 1 slept for 6 h from 0:00 to 6:00, and group 2 napped for 2 h from 13:15 to 15:15. There was no prominent difference in the subjective quality of sleep between the groups. This was supported by the lack of any significant difference in sleep efficiency and latency between the groups. Additionally, the heart rate after the afternoon nap was significantly higher than the baseline level before nap (overshoot), whereas the heart rate in the morning was the same as recorded the night before. The relatively long afternoon nap may be comparable with a night's sleep in terms of sleep quality, whereas it may enhance greater autonomic arousal after awakening than that in the morning. © 2018 Institute of Electrical Engineers of Japan.
