Delhi Records Hazardous Air Quality Above 450 After Diwali, Prompting Health Alerts

Delhi faces hazardous air quality after Diwali celebrations, with particulate matter spiking and AQI readings climbing above 450 across multiple districts of the National Capital Region, a level classified as severe and dangerous for public health.

AQI monitors from IQAir and AQICN report real‑time index values consistently in the 450‑500 range, indicating concentrations of PM2.5 that exceed safe limits by more than tenfold, raising immediate risk of respiratory and cardiovascular stress.

Health Officials advise residents to wear N95 masks, keep windows closed, use indoor air purifiers, and limit outdoor exercise until levels drop, warning that prolonged exposure can impair lungs, heart and brain function.

Alert Services such as DelhiPollution.in and AQICN have issued health warnings, urging schools to keep children indoors and advising commuters to use masks on public transport.
