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!
I always wear loose fitting cotton long sleeves, hats, long trousers and such! Salty food is good to know, ty. Always can be drinking more water too.
Funny enough my job never had real policy around heat, just an informal "drink water take breaks" in apartment buildings lacking AC in August. Lole.
