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!
In the short term, cold showers and wet clothes are useful. Longer term I've found that a bit cardio helps massively with heat tolerance after a week or so. I mean the difference between 21 feeling warm before and 23 feeling chilly after a solid week of cardio.
Cardio, I have not been moving much but yeah maybe... would be good...
Yeah I was honestly kinda shocked, but it really helped. Took a cool shower after and it might as well have been late fall. It'll probably take a week or a few weeks so be patient. But it really helped my heat tolerance.
Cold showers for sure. But I never knew about the cardio thing, will have to give that a try when summer comes around!
