As the title says, I can't seem to tolerate the heat anymore. I've noticed it over the past couple of years. When it's 30 degrees plus I feel weak, lethargic and generally lack energy. I've been in Spain the past 2 weeks in the heatwave and it's been 38 degrees. I can't go for walks in town because it's too hot but my husband it absolutely fine and it results in fights as he doesn't understand how I feel and he wants to do more sightseeing.
When I was younger, up to about 38 years old I was fine in the heat and I could tolerate heatwaves etc but I can't now.
I'm now 43. Could this be peri or something else? Such as thyroid issues? Or is it normal to not be able to tolerate heat in 30 degrees?
No other health issues except anemic due to heavy periods and ferritin of 15.
Thanks.
