Answer 1

Answer:

While it goes without saying that one is supposed to stay indoors, and preferably use an air purifier if affordable, it's also become essential for everyone in the Delhi NCR to wash their face, mouth and nasal tract (nostrils) every three to four hours. This will ensure cleaning up of the nasal tract, so the accumulated toxic particles inside your nostrils don't enter your lungs.
