The high pollution levels in Delhi pose serious health risks, particularly to children, the elderly, and individuals with respiratory or cardiovascular conditions. The 'very poor' air quality can lead to respiratory issues, eye irritation, and other health complications. The widespread use of firecrackers during Diwali is expected to exacerbate the situation, potentially leading to hazardous air quality levels. The government has taken measures such as school closures and encouraging remote work to mitigate the impact.
