@untoldstoriesofhistory: The “8 hours of sleep” rule wasn’t invented by scientists — it came from a labor protest slogan. For most of human history, people slept in two separate blocks with a wake period in between, known as biphasic sleep or segmented sleep. Historian Roger Ekirch found hundreds of historical records proving this was completely normal. Artificial light, industrial work schedules, and modern capitalism erased it — and now we call it insomnia. Everything you’ve been told about healthy sleep might be wrong. #historytok #sciencetok #weirdhistory #History #sleep

I love this …I have begun sleeping when I am tired regardless of what time it is and I work when my energy levels are high…this makes sense society has really made us believe so much that just doesn’t even make sense

Omg you’re telling me that’s why I’ve been waking up in the middle of the night for months now? I’ve been trying to figure out what’s wrong 😭

You just explained my sleep for the last 2 years! I thought it was pain waking me up but maybe it’s not that at all.

I had a really strange spiritual awakening in 2012 and I’ve been a Biphasic sleeper since then. It’s just strange. 3-5am is my favourite time of the day now.

I’m so weird because I do this now. I go to bed near dark. I’m fighting sleep by then. Wake up 2-3 am. Stay up for a couple hours go back to sleep for a short cat nap and get back up around 6-7. If I sleep any longer than in the morning that I have nightmares and I always get up in the middle of the night. Have to do what my body wants or I’m a mess. lol
