The effects of a 20-min nap before post-lunch dip were studied. The subjects participated in nap and no-nap conditions at intervals of 1 week. Their electroencephalogram (EEG) recordings of relaxed wakefulness, mood, performance, and self-rating of performance level were measured every 20 min from 10.00 to 18.00 h. For nap condition, the subjects went to bed at 12.20 h and were awakened after they slept for 20 min. The nap improved subjective sleepiness and self-rating of task performance, and suppressed EEG alpha activity. The results suggest a positive effect of a 20-min nap upon the maintenance of daytime arousal level.
研究了午餐后困倦期前进行20分钟午睡的效果。受试者每隔1周分别参与午睡和不午睡两种情况。从10:00至18:00，每隔20分钟测量他们在放松觉醒状态下的脑电图（EEG）记录、情绪、表现以及对表现水平的自我评分。对于午睡情况，受试者于12:20上床睡觉，睡20分钟后被唤醒。午睡改善了主观困倦感和对任务表现的自我评分，并抑制了脑电图的α波活动。结果表明，20分钟的午睡对维持白天的觉醒水平有积极作用。
