Here I say that the quote, "O sleep, O gentle sleep, nature's soft nurse, how have I frighted thee?" is from "the Scottish play," a euphemism for *Macbeth*. But in fact it's from *Henry IV, Part 2*.

罗素·福斯特是一位睡眠神经科学家，他研究脑部的睡眠周期。他提问：关于睡眠，我们知道什么？事实证明，对于占据我们三分之一生命时光的这件事，我们知之甚少。在此次演讲中，福斯特分享了关于睡眠原因的三种流行的理论，揭示了对于不同年龄层需要睡眠量的一些迷思，也提出了一些大胆的将睡眠作为预测心理健康的新用途。

我们为什么要睡觉？

Sleep is not a passive, wasted stretch of time but a powerful engine for restoring the body and sharpening the mind. On average, people spend 32 years asleep over a 90-year lifespan, yet modern life treats sleep as dispensable. Chronic sleep deprivation damages memory, weakens judgment, and even raises the risk of obesity and heart disease. Powerful new research reveals deep links between disrupted sleep and mental illness, suggesting that sleep is critical not just for daily functioning, but for mental health itself.
