Why Your Ancestors Slept in Two Shifts Every Single Night

You wake up at three in the morning for no obvious reason at all. No nightmare, no noise, just wide awake in the dark. Before you convince yourself something is wrong with you, consider this: for most of human history, that wasn't a disorder. It was simply what a normal night looked like. In this video, you'll discover the forgotten historical pattern of "first sleep" and "second sleep" found buried in centuries of old diaries and court records, the real modern experiment that accidentally recreated this exact pattern under total darkness, and why artificial light quietly erased a rhythm humans lived inside for most of their existence. You'll see why that middle-of-the-night wakefulness might be far more ordinary than you've been taught to believe, and why the anxiety wrapped around it may be the only thing that's actually new.
