It’s that time of year again—when Diwali, meant to be a festival of lights, descends into a festival of noise, smog, and choking air. Despite years of warnings and regulations, large parts of Delhi saw the Air Quality Index (AQI) skyrocket past 500 on the night of Diwali (October 20) and the following morning. To put that in perspective: an AQI of 201–300 is considered "Very Unhealthy", where even healthy people are advised to limit outdoor activity, and anyone with respiratory issues is at serious risk. But anything above 300 falls into the “Hazardous” category—where everyone is advised to avoid outdoor exertion entirely, as the air can cause serious health effects, even in those without preexisting conditions.
