What Ancient Humans Did When They Couldn't Sleep?

It's 3am. You're staring at the ceiling. Your phone is facedown beside you and your mind won't stop replaying something from years ago. You assume something is wrong with you. But the real answer is far stranger — and far older than you think. In this video, you'll discover why waking up in the middle of the night used to be completely normal, what historian A. Roger Ekirch found buried in centuries of pre-industrial diaries, and why hunter-gatherer groups today — with no electricity, no clocks, and no alarms — don't even have a word for insomnia. You'll learn how artificial light quietly rewired your internal clock, why your ancestors' nighttime wakefulness may have kept them alive, and why the real problem was never how much you sleep — it's how you feel about waking up at all.
