I do feel stupid for feeling this. India is currently on fire and also flooding iirc, by contrast here in 
it's not much hotter than recent years. I am lucky enough that we have a portable AC to run in the bedroom.
It's not the literal heat, our room is an ok temp honestly. But the heat seems to be breaking down my joints and bones, I feel like a decrepit corpse weighted with lead rn. This is the first time I'm feeling this too, didn't happen last year so my body is maybe decaying again.
I think it's heat exhaustion, I am making sure to drink and stuff but I just feel sluggish and sore, I am scarfing ibuprofen to little avail. Weh!
100pct, I live in an older house in the midwest so all summer it doesn't get below 85F/60% humidity or so indoors. People barely use window ACs out here, central air doesn't exist frankly, an older neighbor of mine passed when we had our last heatwave, and another had something where he can no longer drive, and despite he former not being reported as a heat death I strongly suspect it was. Window ACs are super expensive to run and I can only cool it into the 80s at best. If I run it all day it'll just ice up on me and be totally useless. I saved up and finally bought a new one (along with a dehumidifier), we'll see how it does.
When it gets as humid as it does here the wet your sheets wet towel business to keep cool doesn't work well. In CA at least it was a dry heat and you could just wet a towel and lie and rot even if it was like 95 indoors with a fan and wet towel, here there's no comfort. I can't do any of my hobbies in summer since its so hot, and its no wonder my mood always tanks in summer. I always wake up sweaty and after work its like coming to a fucking fire. During the heatwave I had to take an ice cube bath, it was so damn hot even my cats joined me.
I've found working out even in the heat helps, just be careful. Drinking spicy things and eating soup also seems to help though this sounds like a poor plan.
