Summary: On Friday, Delhi was covered in toxic fog as the AQI climbed over 700, making residents struggle to breathe under a grey, polluted sky.

Delhi’s air turned almost unbreathable on Friday morning. The city’s air quality index (AQI) crossed 700, slipping into the “hazardous” range, as a mix of pollution, dust, and stagnant air smothered the skyline. The fog was so thick that visibility drastically reduced, and the familiar city dissolved into a dense, grey mist.

Experts are calling it the post-Diwali smoke, continuous stubble burning in neighboring states, and near-still wind conditions that prevented the toxins from escaping. With no wind to clear the hazardous air, everything from fine dust to charred residue clung in the air, making every breath heavier.

The air is now so bad that even healthy people can feel its effects — from burning eyes to scratchy throats and breathlessness. Doctors have warned residents, especially children and the elderly, to stay indoors as much as possible. If you have to step out, wear a mask and avoid any heavy outdoor activity.

It’s one of those days where Delhi feels like it’s holding its breath. The only question now is how long before the air clears — or if the city will have to wait for nature’s mercy again.
