Following Diwali, air quality in several cities across northern India plummeted to hazardous levels, with AQI readings exceeding 400 in some areas. Despite measures such as anti-smog guns and construction restrictions in cities like Delhi, pollution levels remain critical, fuelled by stubble burning and firecrackers, and intensified by the onset of winter. The question remains: How is the AQI calculated, and what factors contribute to its sharp decline, especially during winter?

Diwali celebrations lead to air pollution due to the burning of crackers and the climactic change. Read on as we discuss impact of high AQI on health and how to stay safe.
