Why Ancient Humans Slept Sitting Up?

For almost all of human history, lying flat to sleep wasn't normal — it was rare, risky, even reckless. From short medieval beds and pillow-stacked royal thrones to Breton box beds, Egyptian headrests, forgotten "first" and "second" sleeps, and hunter-gatherers dozing upright around a watchful fire, this is the slow-unraveling story of why our ancestors slept sitting up, and why the deep, flat, dead-to-the-world night you take for granted may be one of the strangest things our species has ever done. So when you climb into bed tonight, ask yourself: are you really sleeping the way humans were meant to? #history #sleep #ancienthistory #humanhistory #sleephistory #historyfacts #anthropology #medievalhistory #segmentedsleep #firstsleep #secondsleep #evolution #hunessgatherers #documentary #didyouknow #sleepscience #historychannel #humanevolution #curiosity #facts
