I read an article by an allergist the other day that reminded me of a co-worker. Part of the reason that she had been living in a high desert area before she moved here was because she had found out that she was allergic to mold. But after moving to the desert, her allergy symptoms got even worse, so she consulted an allergist there.
He told her that she had moved to one of the worst places in the world for those allergic to mold. She told him she was surprised by that because she'd heard that mold loves humidity and moisture so much. He said, "That's the big misconception everyone has about mold allergies. But mold does not in fact *love* humidity or moisture; it merely *likes* humidity and moisture. What mold loves better than anything is heat and even warmth. So since it's always at least warm and usually hot here, we got a lot of mold."
And the article I read recently said the same; the author said that "anyone allergic to mold who wants to spend any amount of time outside should live somewhere where it's cold and dry all year. And since the only places on the planet like that are the North Pole, the South Pole, and northern Greenland, if you're allergic to mold, your best bet is to stay the hell inside."
And being allergic to mold runs in my family, lucky me. At least I don't have the form that my late dad and brother had: they started into anaphylactic shock if they tried taking Penicillin.
