The number of episodes of intervening wakefulness, their duration and their sleep stage occurrence were analyzed in the sleep recordings of 19 young (19-23 years), good sleepers. There were 5 long sleepers (LS), 5 short sleepers (SS) and 9 regular sleepers (RS). The experimental protocol included 2 reference nights, a night sleep recovery (after 36 h of wakefulness) and a day sleep recovery (after 24 h). The night following the day sleep recovery was also recorded. The duration of waking episodes was very stable and was independent both of type of sleeper and of situation. The histogram of these durations seemed to follow an exponential law. The number of awakenings varied according to the individual, the habitual sleep length (SS had very few) and the situation (such as length of prior wakefulness or circadian factors).
对19名年轻（19 - 23岁）、睡眠良好者的睡眠记录进行分析，统计其中间觉醒期的次数、时长及其睡眠阶段分布情况。其中有5名长睡眠者（LS）、5名短睡眠者（SS）和9名正常睡眠者（RS）。实验方案包括2个参照夜晚、1个夜间睡眠恢复（清醒36小时后）和1个日间睡眠恢复（清醒24小时后）。日间睡眠恢复后的夜晚也进行了记录。觉醒期的时长非常稳定，且与睡眠者类型和睡眠情况均无关。这些时长的直方图似乎符合指数规律。觉醒次数因人而异，与习惯性睡眠时长（短睡眠者的觉醒次数很少）以及睡眠情况（如先前清醒时长或昼夜节律因素）有关。
