Tent within a tent.
I was watching a National Geographic show and a fellow was studying the Mongolian people and within their tent hey set a tent or room within the tent Andy he kept it comfortable with like a candle in a glass or metal container. Outdoor temp was well below zero.
Don’t know how he Main Ted safety and not burn it down.
I understand the military does something similar for survival training, those of you would know better than me.
