Structural components of sleep following brief waking intervals were examined. Following an uninterrupted baseline night, 10 subjects were awakened on the next 5 nights for either 20, 40, 60, 90 or 120 min. All awakenings occurred at 02.30 h. During waking intervals subjects sat quietly in an illuminated room. Following each waking interval subjects returned to bed and slept uninterrupted until the next morning. Such awakenings had the effect of increasing the mean duration of the first SWS episode following return to sleep, and increasing the mean duration of first and second REM episodes following return to sleep. Sleep stage sequencing was also affected, with REM sleep preceding the first epoch of SWS in 38% of the sleep episodes following return to sleep. Eye movement density was essentially unaffected by controlled awakenings and timing of the REM/NREM cycle bridging awakenings appeared to be sleep dependent.
对短暂清醒间隔后的睡眠结构成分进行了检查。在一个无间断的基线夜晚之后，10名受试者在接下来的5个夜晚于凌晨2点30分被唤醒，分别唤醒20、40、60、90或120分钟。在清醒间隔期间，受试者安静地坐在有灯光的房间里。每次清醒间隔后，受试者回到床上并持续睡眠直至次日早晨。这种唤醒具有增加重新入睡后首个慢波睡眠（SWS）阶段平均时长的效果，以及增加重新入睡后首个和第二个快速眼动（REM）阶段平均时长的效果。睡眠阶段顺序也受到了影响，在重新入睡后的睡眠阶段中，38%的睡眠时段里快速眼动睡眠先于首个慢波睡眠时段出现。眼球运动密度基本上不受控制性唤醒的影响，且跨越唤醒的快速眼动/非快速眼动（REM/NREM）周期的时间似乎取决于睡眠状态。
