What Did Ancient Humans Do at Night?

What Did Ancient Humans Do at Night? Tonight, when you flip a light switch, you probably won’t think twice about it. But for 99.9% of human history, that switch didn’t exist. For over 300,000 years, your ancestors spent half their lives in a darkness so thick they couldn't see their own hands—and it turns out, that darkness made us who we are.

We dive into the fascinating "lost history" of sleep, revealing that the eight-hour block we struggle to achieve today is actually a modern invention. ⏱ CHAPTERS 0:00 Why you wake up at 3 AM 0:41 Nights before electricity 1:30 The danger in the dark 2:18 The Hadza sleep study 3:26 How long did ancient humans sleep? 4:14 Art in the dark: the caves 5:18 So what did they do all night? 5:56 Why this matters for your sleep Of course, we can't know exactly what every ancient human did after sunset.
