You Were Never Meant to Sleep 8 Hours Straight

Tonight, you'll try to sleep for eight hours straight. You'll probably wake up around 3am and assume something is wrong with you. But the real answer is far stranger: for most of human history, that wasn't a malfunction. It was the plan. In this video, you'll discover the forgotten history of "first sleep" and "second sleep," the quiet hours your ancestors spent awake in the dark, and what they actually did during that time. You'll meet the historian who spent over 15 years uncovering the evidence, and the 1990 experiment that made a modern human body split its sleep in two. You'll learn what killed the two-sleep night, why light changed everything, and why that 3am wake-up might be your biology remembering something your calendar forgot. If this changed how you think about your own nights, hit like, leave a comment with the time you usually wake up, and subscribe for more stories about the ancient truths hiding inside your everyday life. #sleep #segmentedsleep #biphasicsleep #firstsleep #secondsleep #humanhistory #humanevolution #anthropology #psychology #insomnia #3amwakeup #sleepscience #ancienthistory #historyexplained #educationalvideo #doodleanimation #sleephistory #circadianrhythm #sleeptips #didyouknow
