The severe air quality in Delhi poses serious health risks, particularly for vulnerable groups such as children, the elderly, and individuals with pre-existing respiratory or cardiovascular conditions. Prolonged exposure to PM2.5 can lead to respiratory issues, reduced lung function, and other long-term health complications. The situation is exacerbated by stubble burning in neighbouring states and local sources of pollution, including transport emissions, industrial activities, and construction dust. Residents are advised to limit outdoor activities and take precautions to minimise exposure to polluted air.
