I do not do well when in the heat - 70+ I get overheated. Living in the northwest I thought summers would be the worst. Now I've learned summers are more predictable. I do well in the cold but I never know what tempature a building is going to be. I've been at a mall and become overheated and disoriented. Doctors offices seem to be the worse. Whenever I see my primary I get overheated and struggle. Have any of you learned any helpful tricks?
