DESCRIPTION (provided by applicant): The broad aim of this application is to examine circadian timing and daytime function in high school students in the context of weekend recovery sleep behavior. Large disparity between school night and weekend night sleep timing is associated with poor daytime function (e.g., poor academic grades and depressed mood). The first aim of this study is to examine circadian factors that may contribute to this association. Modifying sleep patterns on the weekend to maintain stable circadian timing may attenuate daytime function decrements. Thus, the second aim of this study is to test an alternative weekend sleep schedule that stabilizes the circadian system. The proposed study uses a within subjects counterbalanced design with two conditions that differ only by the following enforced weekend sleep/wake schedules: the commonly observed, late rise time schedule and an alternative schedule with stable nocturnal sleep and an afternoon nap. Circadian phase, subjective sleepiness, cognitive throughput, mood, and vigilance assessments precede and follow each weekend condition. This study may further the understanding of risk factors for poor daytime function and will evaluate sleep behaviors that may attenuate these decrements in teens.

描述（由申请人提供）：本申请的广泛目的是在周末恢复睡眠行为的背景下检查高中生的昼夜节时间和白天功能。上学之夜和周末晚上睡眠时机之间的巨大差异与白天的功能不佳有关（例如，学术成绩差和心情沮丧）。这项研究的第一个目的是检查可能导致这种关联的昼夜节律因素。周末修改睡眠方式以保持稳定的昼夜节律可能会减少白天的功能。因此，这项研究的第二个目的是测试稳定昼夜节律系统的替代周末睡眠时间表。拟议的研究使用主题与平衡的设计，其两个条件仅与以下强制性的周末睡眠/唤醒时间表不同：通常观察到的，较晚的上升时间表和替代性时间表，具有稳定的夜间睡眠和一个下午的小睡。昼夜节律阶段，主观的嗜睡，认知吞吐量，情绪和警惕性评估和每个周末状况之前。这项研究可能会进一步了解白天功能差的危险因素，并评估可能减少青少年减少的睡眠行为。
