flag Pollution worsens rheumatoid arthritis, with studies linking high PM2.5 levels to increased risk and severity, especially in cities.

flag Poor air quality, especially high levels of PM2.5 and other pollutants, is increasingly linked to triggering and worsening rheumatoid arthritis (RA), a chronic autoimmune joint disease, according to experts. flag Studies in Europe, China, and India show pollution contributes to systemic inflammation and oxidative stress, accelerating RA onset and severity, even in people without genetic risk factors. flag Urban areas with heavy traffic and limited green space see higher RA rates. flag Researchers urge urgent action, including stricter pollution controls, expanded green spaces, cleaner transportation, and early screening, as RA has no cure and affects about 1% of adults in India.
