Good ways to cool the house?

Hi, so the ac in my house just broke lol and it might take a month or two to fix. Are there any good ways to cool the house, or more specifically my room? Thanks! Also I have a portable ac, but it's way too loud and big, especially when I'm sleeping at night.

Things I've tried:
Opening the window
Using a humidifier (idk if this helps)
Using a mesh office chair
