I have a very warm and stuffy room. So warm initially I prefer to sleep in the living room. But found the trick.

Blast your fan to fan away those hot air. Once your roon feels cool then keep having the fan on (lowest speed fan will do), just to ensure your room is cool. To save electricity, you can turn it off when you're not around but turn the fan back 3-4 hours before you sleep. And the fan should be on throughout the night, blowing at you. So you get cool air.

It works with mine, zero AC needed.

Inside. So ensure room air is circulating.

You can get those japanese mattress cold padding as well. The fan wind will make it cool
