'Go Wild' (John Ratey, Richard Manning) theorizes that the modern concept of bedrooms in which we segregate ourselves to sleep is a mismatch with our evolutionary established state. We would naturally lie in very close proximity of tribe and family for heat, contact and security. Sleeping and resting on one another out in the open. Perhaps pillows and blankets (esp weighted) serve as a proxy for this, not just temperature?

That would result in insanity for me. Is there any argument other than it seems like cave people must have?

Well, this is probably a thing where humans are very diverse in their subjective experience.

I'd say this is definitely a noticeable thing with small children at family gatherings, birthday parties and the like. But I grew up in a household where both of my parents came from families where big family gatherings with even extended family was common, and I know not everyone has that kind of experience, so who knows how much of that is nature or nurture as well.

In my case however this has persisted well into adulthood: despite being a chronic insomniac who has a really hard time falling a sleep normally, at these types of social gatherings I often have to fight off falling asleep precisely because I feel comfortable and safe among friends and/or family (I wonder if that is in any way related to my ADHD).

I also get sleepy at gatherings. It's something really subtle and hard to defend against, but brutally simple.

It's the food and air quality. There's a lot of people in an enclosed environment eating too many carbs (or too much in general).

Timing is critical and I'm on a mission. Before the heavy food comes out, I grab a seltzer and a small salad. I convince some people to join me on the patio for a drink. It's important to arrive late enough that people are eager to break away, but well before any food ceremony.

Nah, food comas are noticeably different, at least for me. Plus I also had this drowsiness at student parties where I whs the only sober guy (because tee-totaller) while everyone got tipsy, and no food was involved either.

Safety. If something creeps up hopefully one of you is partly awake to raise the alarm. I sometimes think cats are still like this, they seem to sleep very soundly around people but only snooze and are easily startled when isolated.

If I am to believe the creator of the _History in Taberna_ youtube channel, communal beds were a medieval to early modern practice in inns [0].

Not just you. Most are insane already. Temperature, noise, light, other partner, pillows, ventilation, caffeine, wind down (including me as I write this comment) - majority of people mismanage this so badly. We spend 1/3rd of our time on it, it's probably top 5 of most important things in our life, yet we butcher it so badly.

[etrautmann]

I can't disagree with that, myself included. I've gotten MUCH better about caffeine discipline but that's only a start.
