At night, the heat is off. Just a warm comforter is plenty in almost any weather, and the cool air feels great. In fact, I always try to position the head of my bed near a window and even in cold weather, at least crack open the window - breathing fresh air all night feels great.
For anyone who has gone camping, they know that a warm enough sleeping bag is fine, no problem at all, and again, the fresh air is a wonderful part of the experience.
> camping is famously hated by a significant portion of the population
Not very famously, because I haven't heard that. Some people don't like it, I have no doubt. No matter what is suggested, nay-sayers can point to some people not liking it; what does it mean? And the people who don't like camping likely object to other aspects of it - just random chance among many aspects, and many much more burdensome such as carrying all your stuff, the food, less personal sanitation, no TV, no sushi or pizza delivery, etc. etc. I don't recall hearing anyone in my life object to fresh air, but I'm sure someone does!
