The air quality issues in California and North Carolina pose serious health risks, particularly for vulnerable groups such as children, the elderly, and individuals with pre-existing respiratory or cardiovascular conditions. In California, PM2.5 from wildfire smoke can penetrate deep into the lungs and bloodstream, potentially causing asthma attacks, reduced lung function, and heart problems. In North Carolina, ground-level ozone can irritate airways, worsen asthma, and cause chest pain. Both pollutants are linked to long-term health complications, and even short-term exposure can be harmful. Residents in affected areas are urged to take precautions to minimize exposure.
