Home sleep recordings were conducted over four consecutive nights with 12 good sleepers and 12 sleep-maintenance insomniacs. Good sleepers showed decreased sleep efficiency and increased min awake after sleep onset on night 1. Insomniacs showed extended latency to onset of the first REM period and decreased REM in the first third of the initial recording night. Good sleepers and insomniacs reported no significant differences in adequacy of sleep between the first and subsequent sleep nights.
对12名睡眠良好者和12名睡眠维持性失眠患者连续四个晚上进行了家庭睡眠记录。睡眠良好者在第1晚睡眠效率降低，入睡后清醒时间增加。失眠患者首次快速眼动（REM）睡眠期的起始潜伏期延长，且在初始记录夜的前三分之一时间内快速眼动睡眠减少。睡眠良好者和失眠患者报告在第一个睡眠夜与后续睡眠夜之间的睡眠充足程度没有显著差异。
