According to India Today, Dr Arvind Kumar, lung surgeon at Sir Ganga Ram Hospital said,

Intake of every 22 micrograms per cubic metre of polluted air is equivalent to smoking a cigarette. So whether the PM2.5 level is 700 or 300 units, the impact is still as bad. People need to take precautions, especially those suffering from asthma, bronchitis or other respiratory illness.

However, weather experts said that increased wind speed due to a fresh western disturbance would help in dispersing pollutants faster from Saturday.
