In summary, this study of sleep in adolescents on an atypical schedule of 18-hour nights showed marked but not unanticipated differences in sleep as function of prior sleep deprivation. Unanticipated was the evidence of "recovery" sleep in adolescents who not only were not sleep deprived, but who had been on a sleep "optimizing" schedule and had been awake for only 10 hours. Extended sleep beginning about 4 hours in advance of entrained sleep onset phase was not associated with a return of SWS, a finding coinciding with predictions from studies in adults. Finally, this study provides an indication that the homeostatic sleep/wake process becomes less robust or sleep responsive during adolescent development, a phenomenon that may influence the delay of sleep common in adolescents.
总之，这项针对采用18小时夜间非典型作息时间表的青少年睡眠的研究表明，睡眠因先前的睡眠剥夺而存在显著差异，但并非出乎意料。出乎意料的是，在不仅没有睡眠剥夺，而且一直遵循睡眠“优化”时间表且仅清醒10小时的青少年中，出现了“恢复性”睡眠的证据。在与内源性睡眠开始阶段提前约4小时开始的延长睡眠与慢波睡眠的恢复无关，这一发现与成人研究的预测一致。最后，这项研究表明，在青少年发育过程中，稳态睡眠/觉醒过程变得不那么稳健或对睡眠的反应性降低，这一现象可能会影响青少年常见的睡眠延迟。
