目的：本研究的目的是研究的影响，20分钟的午睡在下午对情绪，性能和EEG activities.Methods：7个年轻的成年人谁有正常的睡眠-觉醒习惯，没有习惯性的白天午睡参加了这项研究。他们每隔一周接受午睡和不午睡条件。记录夜间睡眠（00：00-08：00 h）后，每20 min记录一次放松清醒状态下的EEG记录，并从10：00 - 18：00 h记录一次情绪、工作表现和工作表现水平的自我评定。对于午睡条件，他们在14：00上床睡觉，并在睡眠阶段1开始后20分钟被唤醒。在无午睡条件下，他们坐在半躺椅上休息，不睡觉。结果：所有受试者在午睡期间从睡眠阶段2中醒来。20 min的小睡改善了他们的主观嗜睡，绩效水平和任务绩效的自信心。午睡也抑制EEG α活动在眼睛开放wakefuls.Conclusions：结果表明，乳木果20分钟午睡在下午有积极的影响后，维持白天的警惕水平。(C)1999爱思唯尔科学爱尔兰有限公司保留所有权利。
Objective: The aim of the study is to examine the effects of a 20 min nap in the mid-afternoon on mood, performance and EEG activities.Methods: Seven young adults who had normal sleep-wake habits without habitual daytime napping participated in the study. They underwent Nap and No-nap conditions at intervals of 1 week. After a nocturnal sleep recording (00:00-08:00 h), their EEG recordings during relaxed wakefulness, and their mood, performance and self-ratings of performance level were measured every 20 min from 10:00 to 18:00 h. For the nap condition, they went to bed at 14:00 h and were awakened when 20 min had elapsed from the onset of sleep stage 1. For the No-nap condition, they took a rest without sleep by sitting on a semi-reclining chair.Results: All of the subjects were awakened from sleep stage 2 during the nap. The 20 min nap improved the subjective sleepiness, performance level and self-confidence of their task performance. The nap also suppressed EEG alpha activity during eyes-open wakefulness.Conclusions: The results suggest that a shea 20 min nap in the mid-afternoon had positive effects upon the maintenance of the daytime vigilance level.
