Hi Pam, I live in the desert and i can say that even the slightest rise in humidity causes my aches and pains to get worse. One strange thing though is that when we were on vacation on the coast in Oregon I wasn't in as much pain and the humidity was very high there. So is it the humidity plus the higher temps that causes my pain? Or was I not in as much pain because I was distracted by being on vacation at the ocean? One of those Hmmmmmmm moments...Sue
