Well I live in South Florida so hot and humid is part of the course here. I am way worse in cold but am careful to not be out much in the afternoon other then to and from the car or a building. For me I don't do well with changes. More consistent the weather the better. One day cold,one day hot,one day rain my body goes nutty. I wish they had clothes for people with this. I have days in my house I have one pant leg up one down,one sock on one sock off. I look like a mess. What ever it as long as I get through the day.
