lynds,
Yes heat does have an affect on my ability to cope with anxiety and panic. I live in a climate here on Maui that is about the same everyday which helps me tremendously. I recently took a trip to my home town Houston, Texas which really stressed me. Not only the traffic, murder, mayhem, and BIG time heat and humidity had me on edge the entire visit. I am now back on Maui and am happy to say that I am feeling better. I hope you find peace and cool tranquility in your life.
Rose
