It’s an interesting question, and could have imagined people sharing their beds with pets, but with livestock? Is funny. I personally have sleeping problems in rooms that are too warm, and warm blankets don't help. It's not when going to bed but a few hours in - around REM time? I wake up panicking as if I'm suffocating. That's why I always sleep with the window open, also when it freezes on the winter. My SO is not…
Oh god, I'm not the only one who has this? I had trouble sleeping in a room my parents made for me and they wouldn't believe me when I said the room is too hot. If it's like 74F or above or so I can't sleep and I'll just continually wake up with that suffocating feeling. Is there a name for this? It doesn't seem normal and I'm dreading it come summer in a city with no AC...
I wonder if the "suffocating feeling" without an open window might be the result of higher CO2 concentration in the bedroom if it isn't aired regularly enough? Might be worse for smaller rooms without proper ventilation and more noticeable due to the sleeping position being lower than regular standing/sitting? There's also this old trope of plants in the bedroom supposedly being a very bad thing.
