A recent study has discovered the significant role of carbon dioxide (CO2) in the pathogenesis of autoimmune disorders, shedding new light on how environmental factors may contribute to these complex diseases. Autoimmune disorders occur when the immune system mistakenly targets the body’s own cells, and researchers now suggest that elevated CO2 levels, often resulting from air pollution or metabolic changes, may play a role in this process.

CO2 can influence the body’s pH balance, creating a more acidic environment in tissues, which may trigger immune dysregulation. This imbalance can activate immune cells, causing them to attack healthy tissues, leading to the progression of autoimmune diseases such as lupus, multiple sclerosis, and rheumatoid arthritis. Moreover, CO2 exposure may enhance inflammatory pathways by stimulating the production of pro-inflammatory cytokines, which can further intensify immune responses and tissue damage.

The study's findings suggest that elevated environmental CO2 could be a contributing factor to the rising incidence of autoimmune diseases globally. By understanding the mechanisms through which CO2 impacts immune function, scientists may uncover new therapeutic approaches to prevent or manage autoimmune conditions. This research also highlights the importance of environmental health in disease prevention, suggesting that controlling CO2 levels could reduce autoimmune disease risks.
