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 also have trouble sleeping with closed windows, especially when it's colder outside. It's really nice to cuddle up under a heavy warm blanket when it's a bit colder in the room, tho it can make getting up in the morning a real pita when the room cooled out way too much.

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.

Damn, my wife is like that. I'm always cold, winter or summer. But i hate heavy bedding, and prefer light sheets and down comforters. But then, for many years, I slept in a nylon sleeping bag on a foam pad.

Got hit with an unexpected blizzard once when I was on an FTX in Colorado, in December. Pure freaking misery (slept in a mummy bag with a watch cap on). Never been so cold in my life, before or since. My right foot still starts to ache whenever I get cold.

So, I live in Florida now. Usually sleep with just a sheet, until my wife steals it at 3AM and wraps it around herself 5 times so I can't get it back.

I had a Goretex bivvy bag for sleeping outside. And I carried both polyester and goose down bags, and a boiled wool blanket. So I was well prepared.
