A bushcraft trick is to dig a shallow trench, build a fire in it. When you’ve got coals, cover them over with dirt and sleep on top of that. I’d bet that goes back a looooong way.
A year or two ago the YouTube channel primitive technologies did a video where he built under floor heating for his hut with an outdoor fire. It reminded me of how the Romans heated their floors.
I was being pretty stupid once and heated up a rock with a blow torch. The thing was glowing red and was super hot. I’m honestly surprised it didn’t explode…

I’ve got some bad news for you…
That video came out 9 years ago.
Probably better to use hot rocks unless you’ve got good ventilation, otherwise carbon monoxide poisoning

River rocks will if you get them too hot too fast, because they have water inside, and it boils. Drier rocks are usually OK, they might crack though.
I feel like being outside would blow away the small amounts of CO produced by coals (instead of an active fire).
CO is a product of incomplete combustion. Specifically, it is created by ventilation limited partial combustion (i.e. not enough oxygen to make CO2).
So, coals would actually make a lot more CO than a roaring fire would.
Don’t put rocks near fire, especially wet rocks, they can explode
edit: I love that there’s some crying piss-ass following me and downvoting all my stuff. Whatever I said to hurt your feelings: GOOD!
