The 'very poor' air quality in Delhi poses significant health risks, particularly for individuals with respiratory or cardiovascular conditions. Prolonged exposure can lead to respiratory illnesses even in healthy individuals. Areas like Jahangirpuri, with AQI levels in the 'severe' category, are at heightened risk. Neighbouring cities such as Noida and Ghaziabad also face similar challenges, impacting millions of residents. The pollution levels are expected to strain healthcare systems and reduce outdoor activity.
