I pretty much stay out of the heat as much as possible. Several of the medications I'm on can cause me to overheat very quickly when out in the sun/hot temps which can be dangerous so I try to stay indoors in the AC when I'm able to. When I have to go places I wear sunscreen, I burn very easily, and I bring a big cold water bottle with me, I also wear a hat to keep the sun out of my eyes. I try to stay hydrated and avoid caffeine if I'm going to be out in the sun, and I also try to make sure I've eaten enough so I don't get lightheaded. When I'm home I sometimes take semi-cold showers, or put a cool wash cloth or ice pack on my neck or forehead
