What happens to your body when you breathe in polluted air | In Focus

In Focus by The Hindu

Every year in November and December, the residents of Delhi and the National Capital Region, find it hard to breathe. Toxic air chokes the lungs, doctors advise people to avoid outdoor walks and runs, hospital outpatient services overflow with people facing respiratory problems, and there is a call for emergency measures to bring the air quality index down from severe to satisfactory. Meteorological conditions such as cold air and a drop in wind speeds combine with the year-long emanation of pollutants into the air from industries, vehicles, construction as well as stubble smoke, along with festive firecrackers -- and together they contribute to the noxious air that prevails across the Indo-Gangetic plain at this time of the year.

What happens to your lungs and body when you breathe in polluted air on a daily basis? How does this impact our health long term? Where does India stand in its pollution levels compared to the rest of the world? And what urgent action can governments take to protect, and help provide cleaner air for future generations?

We speak on this and more in this episode.
