Not entirely related, but sleeping hot I've managed to mitigate the terrible sweaty nights in summer by using an outlast topper. It's not a miracle, but at least I just feel hot and not incredibly hot. I honestly didn't believe it would do something, but it does something

I lived on an island in the middle of the Panama Canal for a few years, one of the hottest and most humid places imaginable. We had no AC. Everyone used a top sheet instead of a comforter or blanket, and had a ceiling fan going at night. It worked surprisingly well.

Ceiling fans are really underrated. Even if you have AC, you can probably save money/energy at night by running the AC at a higher temp with a ceiling fan.

I go camping often throughout the year, and sometimes sleep in a tent in 85-100+F weather. If I put a box fan at the foot of the bed, blowing straight over me, it will cool me down to the point where I wake up and pull a blanket over me. (I always start with a sheet because cool air blowing directly onto on the bottom of my feet is uncomfortable.) Don't underestimate the power of the simple box fan.

Wait, camping and box fan don't exactly jive in my mind. Car camping with electric I suppose?

Camping for me is 30lbs in a backpack. Definitely no fans or power banks.

I've found thermal cooling with a bit of a dab of cold water on my body (sleeping above duvet), with a fan blowing on it for a few minutes is enough to get me to sleep.

My memories of sleeping in 40+ degree C weather when I was a kid by using a wet towel as a blanket are coming back to me

Personally I use air conditioning but for those that can’t this is great advice

Even with AC air gets trapped between the mattress, the person, and covers. Different materials help circulate air and keep a cooler feel.

True, then you don’t have to use as much electricity too
