Air pollution is a bigger problem in India than most parts of the world, and it’s not going away anytime soon. In the coming years, I expect the problem to worsen before it starts improving.
The air pollution in India is causing almost a million deaths every year. Even worse is the suffering caused to many millions more who have respiratory distress (asthma, for example). Imagine being unable to breathe or sleep properly because of respiratory distress.
Our advice to people is to protect themselves using n95 masks on all heavily polluted days and, for people with asthma, allergic rhinitis, COPD, etc., on most days.
Also, people must take precautions to reduce indoor air pollution by using kitchen exhaust fans/chimneys and vacuum cleaners for dusting. They must guard against mould and use indoor air purifiers on polluted days.
