#HumanHistory #SleepScience #evolution Your 2 A.M. Wake-Up Isn't Insomnia. It's 60,000 Years Old. What Did Ancient Humans Actually Do at Night? For thousands of years, humans didn't sleep the way we do today. Instead of one long eight-hour sleep, many people naturally slept in two separate phases, waking peacefully in the middle of the night before returning to sleep. In this documentary, we explore the forgotten history of biphasic sleep, the mysterious Watch Hour, and why waking up at 2 or 3 AM may not always be as unusual as it seems. You'll also discover how artificial light changed the way humans sleep and what modern science has revealed about our ancient biological rhythms. In this video, you'll discover: Why humans once slept in two separate phases. What people actually did during the mysterious Watch Hour. How the Industrial Revolution changed human sleep forever. Dr. Thomas Wehr's famous sleep experiment. Why some people naturally wake up in the middle of the night.
