Winter over here in New Zealand, but when it is summer, it gets pretty warm, I have never had any of these issues, I usually stay inside during the hottest part of the day, if I want to take a walk, or go out in the car, I do it early or later in the day. I don't get sunburned as I don't stay in the sun too long, plus, I put on a good sunscreen and wear a hat when I remember. Summer is not my favorite time of year, but I manage to survive.
