What Ancient Chinese Medicine Knew About Sleep That We Forgot

#WhyYouCantSleep #AncientChineseMedicine #SleepExplained That bottle on your nightstand was never the explanation. It was the replacement for one — and the original is about two thousand years old. An ancient medical text didn't give tips for falling asleep. It described why sleep happens at all, in a way nobody kept. Here's the part that got to me: a modern sleep lab, working centuries later with no knowledge of that text, reached for the exact same word to describe the exact same moment of the night. That's what this video is about — four pieces of a lost explanation, what we put in their place, and what's been measured since.
