I guess I'm the odd ball on the cold temps. I actually fare better when it is cold. When I get over heated, things go bad. I have noticed that I even get flares if the heat is on in the car. My face will start hurting and I get so exhausted. When I cool back down, I'm fine. This is especially true when running/exercising. My legs do not function when I get over heated. A few weeks ago, it snowed and I had to use the treadmill. I ended up sitting outside in my shorts in the snow bawling like a baby because I was so frustrated that my legs would not move right. After cooling off, I was able to go back in and finish up. My husband thought I was losing my mind. Poor guy. He sees a lot of mood swings.
