Classically the human life-course is characterized by youth, middle age and old age. A wide range of biological, health and cognitive functions vary across this life-course. Here, using reported sleep duration from 730,187 participants across 63 countries, we find three distinct phases in the adult human life-course: early adulthood (19-33yrs), mid-adulthood (34-53yrs), and late adulthood (54+yrs). They appear stable across culture, gender, education and other demographics. During the third phase, where self-reported sleep duration increases with age, cognitive performance, as measured by spatial navigation, was found to have an inverted u-shape relationship with reported sleep duration: optimal performance peaks at 7 hours reported sleep. World-wide self-reported sleep duration patterns are geographically clustered, and are associated with economy, culture, and latitude.
传统上，人类的生命周期分为青年期、中年期和老年期。在此过程中，广泛的生物学、健康和认知功能存在差异。在这里，我们使用来自 63 个国家的 730187 名参与者的报告睡眠时长数据，发现成年人的生命周期中有三个不同的阶段：青年期（19-33 岁）、中年期（34-53 岁）和老年期（54 岁以上）。这些阶段在文化、性别、教育和其他人口统计学方面都很稳定。在第三个阶段，随着年龄的增长，自我报告的睡眠时间增加，而认知表现，如空间导航能力，与报告的睡眠时间呈倒 U 型关系：最佳表现出现在报告的 7 小时睡眠时间。全球范围内的自我报告的睡眠时长模式在地理上呈现聚类分布，并且与经济、文化和纬度有关。
