The Forgotten Instinct That Still Controls Your Sleep

Tonight, around 3am, you're going to wake up for no reason. You'll blame stress, or coffee, or your phone. But the real reason is far older than any of that. In this video, you'll discover why humans didn't always sleep in one long block, what a forgotten 1990s sleep experiment revealed when modern light was removed, and why that middle-of-the-night wake-up might be one of the oldest survival systems your body still runs. You'll also see why your 3pm energy crash isn't random either, and what two ancient rest patterns modern life quietly erased.
