Introduction

Air pollution isn't just a nuisance—it's a silent public health crisis impacting millions around the globe, particularly in urban areas notorious for their high pollution levels. Alarmingly, research indicates that exposure to airborne pollutants could be a significant factor in the rise of autoimmune diseases. These conditions, where the body’s immune system mistakenly attacks its own cells, include rheumatoid arthritis, multiple sclerosis, lupus, type 1 diabetes, and inflammatory bowel disease.

Sources of Air Pollution

Pollution primarily stems from vehicles, industrial emissions, and other toxic waste, releasing fine particulate matter (PM2.5), nitrogen dioxide (NO₂), and other harmful chemicals. When inhaled, these substances can trigger chronic inflammation and immune dysfunctions, setting the stage for various health complications.

Autoimmune Diseases Linked to Air Pollution

Here’s a deeper look at five autoimmune diseases that may be linked to air pollution:
