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-國大醫學院研究人員對2,000名12至18歲新加坡青少年的睡眠時長進行了測量，發現學校日的平均睡眠時間為6小時55分鐘——比美國睡眠醫學學會對這個年齡組建議的8至10小時少了近2小時。新加坡在全球青少年平均睡眠時長中排名倒數第二，僅次於韓國。
青春期是神經系統密集重塑的時期。前額葉皮質——管理衝動控制、風險評估、情緒調節和執行規劃的區域——直到20多歲才完全髓鞘化。睡眠正是大部分重塑工作發生的時候。
睡眠不僅是休息——它是主動的學習鞏固。哈佛醫學院睡眠研究項目的研究表明，學習後24小時內的睡眠使程序性技能的保留率翻倍。考前熬夜複習的諷刺之處在於，這反而降低了知識留存的可能性。
