If you suffer from arthritis, you have probably noticed how weather sometimes affects it.<\/p>\nIf you suffer from arthritis, you have probably noticed how weather sometimes affects it.<\/p>\n
But what is the worst climate for arthritis?<\/p>\n
A new study in the journal Scientific Reports<\/em> sheds some light on this and the results may surprise you.<\/p>\n A group of researchers used two groups of rats: some that were healthy and some that had collagen-induced arthritis (CIA). This is similar to rheumatoid arthritis in humans.<\/p>\n They placed both groups in high humidity chambers (80% humidity) to mimic the environment that human patients complain about.<\/p>\n They then examined the rats’ joints for signs of damage and inflammation and checked out their gut bacteria and body chemistries.<\/p>\n The researchers made some interesting discoveries:<\/em><\/p>\n 2.\tHumidity also had some negative effects on the joints of healthy rats, suggesting that high humidity may pose a risk even before the onset of arthritis.<\/p>\n 3.\tThe gut bacteria of both healthy and CIA rats changed in response to high humidity. There were more bacteria linked to inflammation present. <\/p>\n 4.\tThe body chemistry of the rats, as measured by metabolites, also changed significantly in both groups. These changes were linked to inflammation and oxidative stress.\n<\/dd>\n<\/dl>\n These findings are a bit alarming. It suggests that high humidity might be a risk factor for rheumatoid arthritis development or worsening of symptoms.<\/p>\n It also hints at a possible mechanism: high humidity might influence gut bacteria, which in turn affects the body’s chemistry and promotes inflammation.<\/p>\n\n
