I am currently in North Carolina and while I will acknowledge it is hot, and the humidity doesn’t help, it isn’t particularly irritating. It’s like a hug from the air. I’ve been to New Orleans at the end of summer when it’s supposedly bad but I enjoyed it. It almost makes the heat a little bit more bearable because there is something to work with?
Can confirm humidity doesn’t help. Salt water drying on your skin can also make it worse, just a fun fact, so rinse off as often as you can when leaving the water to help prevent it.
Also these people are insane. I’ll take a dry heat over humidity I can’t hardly breathe through any day. Sweat exists for a reason, humidity won’t let you benefit from it.
