What Ancient Humans Did With 16 Hours of Darkness

What Ancient Humans Did With 16 Hours of Darkness Tonight you'll turn on a light without thinking. But for 99.9% of human history, that wasn't an option — and what your ancestors actually did in sixteen hours of darkness will completely change how you see yourself. You'll discover why early humans didn't sleep when darkness fell, what they talked about around fire that modern humans have almost entirely lost, and why your 3am anxiety, your love of stories, and your inability to sit in silence are all relics of the same ancient night. Scientists like Jerome Siegel, Polly Wiessner, Roger Ekirch, and Satchin Panda have spent decades uncovering this hidden history — and almost none of it has made it into mainstream conversation. Until now. If this made you think, share it with someone who stays up too late.
