Key Takeaways
Singapore teenagers average 6h 55min of sleep on school nights — nearly 2 hours below the 8–10 hour recommendation, second-worst globally after South Korea.
Teen late sleep is biological, not laziness: puberty shifts the circadian clock ~2 hours later, making it physically impossible to fall asleep before 11pm for most 15-year-olds.
Each additional hour of sleep per night is associated with a 20% reduction in adolescent depression risk — sleep is the highest-leverage mental health intervention available to parents.

2019年杜克-国大医学院研究人员对2,000名12至18岁新加坡青少年的睡眠时长进行了测量，发现学校日的平均睡眠时间为6小时55分钟——比美国睡眠医学学会对这个年龄组建议的8至10小时少了近2小时。新加坡在全球青少年平均睡眠时长中排名倒数第二，仅次于韩国。
青春期是神经系统密集重塑的时期。前额叶皮质——管理冲动控制、风险评估、情绪调节和执行规划的区域——直到20多岁才完全髓鞘化。睡眠正是大部分重塑工作发生的时候。
睡眠不仅是休息——它是主动的学习巩固。哈佛医学院睡眠研究项目的研究表明，学习后24小时内的睡眠使程序性技能的保留率翻倍。考前熬夜复习的讽刺之处在于，这反而降低了知识留存的可能性。
