Smog affects the heart, blood vessels, and lungs. “PM2.5” particles, which are less than 2.5 micrometers in diameter, can penetrate deep into the lungs and cause inflammation and oxidative stress; some of their components may also enter the bloodstream. Prolonged exposure is associated with increased risks of heart attacks, strokes, high blood pressure, and heart failure. It may also worsen asthma, impair lung function, and increase the risk of respiratory infections and lung cancer over the long term. Experts recommend wearing N95 masks and using HEPA air purifiers, limiting outdoor activity when pollution levels are high, and keeping windows closed. Chest pain, sudden shortness of breath, or fainting requires urgent medical evaluation.
