Yeah, I don't know. The heat here is awful from May until the end of September. Even then, there are many days outside of those where it is hot. There have been times I've worn shorts on Christmas (usually not, but it does happen from time to time here). I'm basically in a suburb of Houston, older parts of my town oceanfront, but not where I live. The weather is not only hot but horribly humid. We've driven from home to California (LA area, where my husband is from), with rest stops along the way in desert areas over the summers with temperatures of something like 110 degrees. That doesn't even feel half as bad as 90 degrees here with 85% (or higher) humidity.

And yeah, I'm prone to sunburn to start with since I have blonde hair, blue eyes, and a fair complexion. I have fibromyalgia too, and I think I remember the doctor once telling me it could make me more sensitive to heat.

Not sure about the sweating this morning, if it was during or after exercise. By the time I got into the house, I was dripping buckets.

I know I got too much heat this morning. When I got in from that run, I basically took off all my clothes except my underwear and collapsed on the floor for awhile (well, I didn't really collapse, felt like it though, and I didn't pass out, but, yeah, I definitely was not feeling great).
