It's harvesting season in the country and some farmers are lighting crops on fire, adding to the smog that was already in the air from cars and coal-fired power plants.
Often after rice and wheat stalks are chopped down in the fall, farmers will set their fields ablaze. The slash and burn technique helps planters clear their fields quickly and gets the soil ready for fresh plantings.
Conditions are expected to get worse this weekend.
The haze is also wafting over Pakistan where Reuters reports road accidents are up and 15,000 people have been hospitalized. Authorities are planning to use fire trucks to spray down parts of the Indian capital, which they hope will help clear the air.
The country is now the world's largest emitter of sulfur dioxide from coal-fired power plants.
One writer at Quartz India even went so far as to say the smog now "heralds the winter" in his home country.
