I’ve lucky bc I work nights and have ac. But when it’s really bad I use ice packs on my neck. I believe they might actually sell things to cool you off that you can put in the fridge then on ur neck. I know they have bandannas like that for dogs, so I’d assume there is a human version somewhere
I found these like cooling gel pack bandanas on Amazon for like $12. They have literally saved me this summer with no AC, I just soak them in water and put them in the freezer for 10 min and they’re literally amazing. If I have to go out it also just looks like I tied a bandana around my neck or in my hair, so super subtle too!
