Delhi-NCR's air pollution crisis: How to stay safe

The Delhi-NCR region has once again turned into a gas chamber. With thick smog and Air Quality Index (AQI) crossing the 300 mark, the air is now in the 'very poor' category, making it hard to breathe for millions. Doctors report a sharp increase in respiratory, cardiac, and vision problems. Dr. Sanju Purohit from Akamai University says, "Delhi NCR is a gas chamber right now. Even healthy people are experiencing headaches, itchy throats, and watery eyes."
