The 'very poor' to 'severe' air quality poses health risks, particularly for vulnerable groups such as children, the elderly, and individuals with respiratory or cardiac conditions. Prolonged exposure can lead to respiratory illnesses and exacerbate existing health issues. Healthy individuals may also experience breathing discomfort. Neighbouring NCR cities, including Noida, Gurugram, and Ghaziabad, are also experiencing poor to very poor air quality, with some areas recording AQI levels above 400. The combination of stubble burning, vehicle emissions, and weather conditions is expected to keep pollution levels high in the coming days.
