I live in AZ. Very little humidity usually but extreme heat from now until October. It’s 96 now at 9:30 am and it’s going to 106!
I am absolutely certain that the heat affects my level of exhaustion and a general malaise I feel more during hot weather than cooler weather. And, humidity just makes it worse.
I do take care to stay hydrated and spend as little time out of doors as possible and when I need to I take a nap (something I rarely did before I was diagnosed with PV/JAK2).
My mother used to tell me when I was much younger and she was in her sixties and would complain I was tired that I had no idea what tired was.
I’m 78 now and she was oh so right and the PV doesnt help.
I force myself to do things I know will tire me out because I’m not going to let PV completely control my life but I do realize limitations and the signals my body gives me that tell me to stop and rest and take that nap when I must.
