What Ancient Humans Did When They Couldn't Sleep

It's 3 a.m. Your eyes are open and your mind won't stop. Something feels wrong with you. But what if it isn't? What if this moment — the one you're having right now in the dark — used to be completely normal? For most of human history, humans didn't sleep in one long unbroken block. They slept in two. A historian named Roger Ekirch found hundreds of references to "first sleep" and "second sleep" in old diaries and letters. A researcher named Thomas Wehr proved it still happens in your body today. And communities studied by Jerome Siegel show almost no chronic insomnia at all. The answer to why you wake up at 3 a.m. isn't broken sleep. It's something much, much older than that.
