The rising pollution levels pose significant health risks, particularly for individuals with pre-existing conditions such as hypertension, diabetes, high cholesterol, obesity, and heart disease. However, even healthy individuals are not immune to the effects of prolonged exposure to polluted air. PM2.5 particles can increase blood pressure, disrupt blood clotting, and accelerate atherosclerosis, raising the likelihood of strokes. The situation is particularly concerning in northern India, where winter smog leads to prolonged exposure to hazardous air, affecting millions of residents.
