Abstract

We investigated the consequences of sleep restriction (SR) on maintenance of wakefulness capacities and diurnal sleepiness through microsleeps monitoring. 12 healthy males (20-36 years old) were sleep restricted (4 h per night) during 7 nights followed by 13 nights of recovery sleep. Participants completed Karolinska Sleepiness Scale (KSS) and Maintenance of Wakefulness Test (MWT) at baseline (B), during SR (SR1, SR4 and SR7) and during recovery (R3 and R13), while continuously recorded for EEG analysis. During SR, MWT latencies decreased (SR7: -24.4%), whereas the number, the cumulative duration of microsleeps and KSS scores increased. Recovery nights allowed MWT latencies, KSS scores and all sleep values to return to baseline levels, while a rebound in N3, N3% and REM% sleep stages occurred. During SR, the maintenance of N3 sleep duration seems not sufficient to reduce daytime sleepiness and MWT results did not reflect the sleepiness levels characterized by persistent sleep attacks.

摘要

我们通过微睡眠监测研究了睡眠限制（SR）对维持清醒能力和日间嗜睡的影响。12 名健康男性（20-36 岁）在 7 个晚上内被限制睡眠（每晚 4 小时），随后进行 13 个晚上的恢复性睡眠。参与者在基线（B）、睡眠限制期间（SR1、SR4 和 SR7）和恢复期间（R3 和 R13）完成了 Karolinska 嗜睡量表（KSS）和维持清醒测试（MWT），同时进行脑电图分析。在睡眠限制期间，MWT 潜伏期缩短（SR7：-24.4%），而微睡眠的数量、累积持续时间和 KSS 评分增加。恢复性夜间使 MWT 潜伏期、KSS 评分和所有睡眠值恢复到基线水平，而 N3、N3%和 REM%睡眠阶段出现反弹。在睡眠限制期间，维持 N3 睡眠时间似乎不足以减轻日间嗜睡，并且 MWT 结果并未反映出以持续嗜睡发作为特征的嗜睡水平。
