I have been keeping track of my RA symptoms in order to minimize them as much as possible. I have noticed that my RA symptoms are more pronounced when it is very humid, even though it's warm, which should make me feel better. My rheumy told me that there are European studies which do connect humidity and RA symptoms, but not much going on in the US. Does anyone have info on humidity vs. RA. I may use this info to choose where we retire in the near future.
Come live in "dry, hot Arizona"......it hardly ever rains so we don't have many days with humidity at all. YES, the humidity does irritate my RA when it does rain. We retired here 9 years ago (central AZ, near Phoenix) and I hate to think what my RA would be like if we still lived near Chicago Illinois. YIKES
I do have some links on RA and whether in general that I can give you - specifically RA and barometric pressure (and another one here). From the research I've done, it seems that different people react differently - some experience an increase in symptoms with humidity (I'm one of them), but for others it's barometric pressure. The best way to find out is to do a symptom diary - which you've already done - and it seems to indicate that humidity is a trigger for you. What the research says doesn't really matter in that respect - what matters is your experience.
However, before you pull up stakes and move to somewhere dry, I'd recommend that you do sort of "dry run" (pun not intended, but sort of funny anyway 
) and spend some time in a dry locale, like Arizona or New Mexico to see how you react. Unfortunately, going somewhere for two weeks on vacation is not going to tell you much - the very fact that you're on vacation will automatically make you feel better. If it's possible for you to spend a couple months there, you may get better data.

Thanks, V, for that great article! Ok, so I'm not so crazy after all. My rheumy seems to be right about more studies done in other countries and not so much in the US.
