Before I retired, my job entailed loads of international travel. I would continually be switching climates and had major time zone shifts. During this time, I didn't notice my RLS very much although I do admit that I developed some coping strategies for all the hours and hours that I spent on planes. I never had any added RLS problems as a result of any changes in climate (this included tropical Africa, the Middle Eastern deserts, Alaska in winter, etc.)I am wondering if anyone has noted a difference in their RLS symptoms when they travelled from the northern to southern or southern to northern hemisphere.
It was only after I retired and stopped all the travel that my RLS went from an occasional annoyance to a major problem. There is no medical information to support this yet, but I suspect that the continual disruptions to my circadian rhythm by jet lag helped to minimize the RLS symptoms. My body was continually trying to reset what time of day it should be, so our nighttime issues often didn't catch up with where I really was. I also feel that my RLS helped me to function more effectively than my fellow travelers during the jet lag recovery time thanks to our ability to live our lives during the daytime even though we had a terrible night.
