#SecondSleep #AncientHumans #SleepHistory #Insomnia It's 3 a.m. and you're wide awake. But what did ancient humans do when they couldn't sleep? Long before electricity, our ancestors didn't fight the night. They used it. In this video, we explore the history of sleep, from Stone Age campfires to the first beds ever built, and uncover why waking up in the middle of the night may be completely natural. You'll learn how hunter-gatherers like the Hadza, San, and Tsimane sleep with almost no insomnia, what Thomas Wehr's famous experiment revealed about biphasic sleep, how historian Roger Ekirch found hundreds of records of "first sleep" and "second sleep," and how street lighting and Edison's light bulb broke a sleep pattern that lasted for thousands of years. If you've ever asked "why do I wake up at 3 a.m.?" or "is waking up in the middle of the night normal?", this video will change how you see your nights. ⏱ CHAPTERS 0:00 It's 3:07 a.m. 0:53 The mystery of ancient sleep 1:15 The wristband experiment: Hadza, San and Tsimane 2:13 One night in the Stone Age 2:56 Wehr's lab and the lost second sleep 4:20 The oldest beds in history (200,000 years ago) 5:05 The night watchmen: why someone was always awake 5:38 What people did in the middle of the night 6:50 Who stole your night?
