The 'severe' air pollution in parts of Delhi poses significant health risks, particularly for individuals with respiratory or cardiovascular conditions. Healthy individuals may also experience adverse effects such as irritation in the eyes, throat, and lungs. The situation is exacerbated by seasonal factors like stubble burning and firecracker emissions, which contribute to the already high levels of pollutants in the air. Vulnerable groups, including children and the elderly, are at heightened risk during this period.
