While a cheap evaporative cooler doesn't help with the humidity you can boost the cooling effect dramatically by adding cooler blocks to the water and even more by placing more cooler blocks in a plastic under-bed container in front of the fans.
If the sound is disrupting then closing the bedroom door and running it in the evening before bedtime works fine.
Cooling yourself with evaporative anything is counterproductive: the extra humidity reduces your body's ability to cool off with sweat.
Essentially, it transforms dry heat into wet heat, which is much worse.
And OP's sweat problem is gonna get much worse.
If you wanna get cool, there ain't too many ways to avoid getting an AC.
There is a dehumidifier setting on most ACs that does the job well at about 10% of the cost. We use this in Spain with the temperatures, when they're reasonable but high with humidity.
Most portable units you will need a tube/bucket set up for the runoff.
We use the water accumulated to water our plants...Win-Win.
I have a dehumidifier at home that does only this and the heat is exhausted indoors instead of outside...
It's not that useful as the room heats up more than the humidity being removed is worth, but I'm considering getting a cheap portable ac unit but I'm worrying about how to install it on my window... And the efficiency being much worse than a properly-installed heat pump where I can close the window when I use it...
oh no, the excess heat should be vented outside, usually with a tube connected to something rigged up to close the window.
We've used cardboard cut to fill the gap, with a circle cut out to fit the tube, and the whole thing sealed with duct tape.....ugly but got the job done so you can sleep (and make a better solution)
Yeah, I'm aware the heat needs to go outside... But I'm not a fan of isolating things with cardboard. And the dehumidifier is just that and doesn't have an exhaust pipe.
I think this is key, you need to cool the room enough for it to not qualify as heat anymore.
