I understand cold weather making my joints hurt but why does the hot weather?

It seems counter intuitive

Pain is usually caused by inflammation. Inflammation can be exacerbated by heat. Esp damp heat.

Heat makes things expand increasing pressure and friction. Plus inflammation.

I have the same and googled it. It's dehydration - means your joints don't have enough synovial fluid to lubricate them.

It's really not fair to get it both ways

I drink plenty as I have a bladder thing

I'm the same the heat really trigger my joint issues and arthritis.
