大多数建议是成年人每晚应获得7-8小时的睡眠，尽管自我报告的睡眠需求存在个体差异。生理时钟类型（偏好早睡或晚睡）与社会需求相结合，可能会影响获得充足睡眠的能力。这项问卷调查研究评估了波士顿科学博物馆参观者在一周和周末的睡眠时间和持续时间。年龄的增长与更大的早晨有关。在调整了年龄因素后，我们发现，时间类型和自我报告的睡眠需求之间，或者时间类型和工作日睡眠持续时间之间没有显着联系。然而，我们确实发现，更大的夜晚与自我报告的睡眠需求和工作日睡眠时间之间的差距更大有关。在周末，更大的夜晚与更长的睡眠时间和更长的睡眠时间相关，睡眠时间的延长是通过更晚的醒来时间实现的。总之，这些研究结果表明，晚上类型在一周内积累了睡眠债务，尽管报告了与早晨类型相似的睡眠需求和持续时间，晚上类型然后试图弥补周末失去的工作日睡眠。睡眠需求和睡眠持续时间的研究应该考虑到时间类型，时间类型的研究可能会受到年龄和晨起之间的关联的混淆，并且必须在选择标准和/或分析中考虑这种潜在的混淆。
Most recommendations are that adults should obtain 7–8 hours of sleep per night, although there are individual differences in self-reported sleep need. Chronotype (preference for early or late sleep timing), in combination with social demands, may affect the ability to obtain adequate sleep. This questionnaire study assessed perceived sleep need and self-reported sleep timing and duration during the week and on the weekend with respect to chronotype in visitors to the Museum of Science in Boston. Increasing age was associated with greater morningness. After adjusting for age, we found no significant association between chronotype and self-reported sleep need, or between chronotype and weekday sleep duration. However, we did find that greater eveningness was associated with a larger gap between self-reported sleep need and weekday sleep duration. On weekends, greater eveningness was associated with a longer sleep duration and greater extension of sleep, with the sleep extension achieved by later wake times. Together, these findings suggest that evening types accumulate a sleep debt during the week, despite reporting a similar sleep need and duration as morning types, and evening types then attempt to make up for that lost weekday sleep on the weekends. Studies of sleep need and sleep duration should take chronotype into account, and studies of chronotype may be confounded by the association between age and morningness, and must account for this potential confound in selection criteria and/or analysis.
