众所周知，困倦有时是在下午经历的。午后短暂的午睡被认为能有效地减少困倦。然而，即使在短暂的午睡后也会出现睡眠惰性，这可能是老年人摔倒受伤的一个主要风险因素。在本研究中，自我觉醒对20分钟后的睡眠惯性的影响。检查NAP。9名参与者(男=74.1岁，SD=5.0岁)参加了三种实验条件：自我觉醒的午睡、强迫唤醒的午睡和对照(不午睡)。分析表明，与对照条件相比，小睡后的困倦和表现明显改善。P3波幅在自我觉醒后趋于大于强迫觉醒后。目前的研究表明，20分钟。午睡可以减少午后的困倦，而自我觉醒的应用可能有助于这一老年群体午睡后的更高唤醒。
It is well known that sleepiness is sometimes experienced in the afternoon. A short afternoon nap is thought to be effective in reducing sleepiness. However, sleep inertia occurs even after a short nap, and this could be a major risk factor for injuries from falling by the elderly. In the present study, the effect of self-awakening on sleep inertia after a 20-min. nap was examined. Nine participants (M = 74.1 yr., SD = 5.0 yr.) took part in the three experimental conditions: the self-awakened nap, the forced-awakened nap, and the control (no-nap) conditon. Analysis showed sleepiness and performance after the nap significantly improved compared with the control condition. P3 amplitude tended to be larger after self-awakening than after forced-awakening. The present study indicates a 20-min. nap reduces afternoon sleepiness, and the application of self-awakening may contribute to higher arousal after a nap taken by this elderly group.
