What's your source for that specific biphasic schedule? Piotr Wozniak has quite convincing hormonal evidence that seems to indicate to me that humans are meant for a full night of sleep and a nap -- which is still biphasic, but not in the sense you describe.
- tinyhouse 3y agoHard to imagine anything different. Without light and frequent bordem (no phones etc.), very unlike to stay awake for 15 hours straight.
- kqr 3y agoI don't think either of us are claiming 15 hours straight. GGP is claiming something along the lines of AAAAAAAAAAAASSSSSSAASSSS repeated, with A=awake and S=sleeping hours, which is 12 hours straight at most. What I remember Wozniak claiming is something like AAAAAAASAAAAAAAASSSSSSSS, which would be 8 hours straight at most.
- gabrielsroka 3y agoAAAAAAAAAAAASSSSSSAASSSS = A12, S6, A2, S4 AAAAAAASAAAAAAAASSSSSSSS = A7, S1, A8, S8
- euroderf 3y agoCats sleep 16 hours a day so I guess it might work out as something like ASSASSASSASSASSASSASSASS. You're welcome.
- rrrrrrrrrrrryan 3y agoHumans: AAAAAAAAAAAAAAAASSSSSSSS Cats: ASSASSASSASSASSASSASSASS Sounds about right.
- rrrrrrrrrrrryan 3y agoThe Thomas Wehr experiment [1] in the 90s (which showed that people settle into 2 distinct periods of sleep throughout the night when they're removed from all artificial light), as well as Roger Ekirch's [2] historical research (which documented the mentioning of "first sleep" and "second sleep" throughout many cultures in pre-industrial society).

- kqr 3y agoThanks! It's hard to tell from a glance how realistic the Wehr experiment was in terms of simulating a workday, but I'll look into it! The historic research seems focused primarily on the biphasicity of sleep, but I'll see if I can find out what evidence there are for specific biphasic schedules.
- moffkalast 3y agoThe problem is that we don't all have the same sleep schedules, which makes sense so the tribe would naturally have some people awake at all times to watch for predators. This doesn't mesh with our modern world where everyone needs to conform to the majority's work schedule. Trying to find a universal inherent schedule that everyone can follow to the letter is fundamentally based on wrong assumptions.
- dpc050505 3y agoOur modern world has people working the night shift, service workers that finish around midnight (restaurants) or in the middle of the night (bars), people on vacation or who don't work and stay up late, night people who get to make up their own schedule, etc. The fact that working a 9-5 is the social norm doesn't mean everyone does that.
