The severe air pollution in Delhi poses significant health risks, particularly for vulnerable groups such as children, the elderly, and individuals with respiratory or cardiovascular conditions. Prolonged exposure to high levels of PM2.5 and other pollutants can lead to respiratory infections, heart diseases, and other health complications. The situation is exacerbated by the onset of winter, which traps pollutants closer to the ground. The use of firecrackers during Diwali is expected to further worsen air quality, potentially leading to an increase in health-related issues for residents.
