Jayesh Hirnandani, a 49-year-old chartered accountant, had to be hospitalised in AIIMS, as he was afflicted with acute chest pain and coughing. “In 2017, we all had heard about how toxic Delhi’s air had become when it was covered under a thick blanket of smog. Last year, I had to face the ill-effects of it. The coughing and chest pain was so terrible that I had to get my chest examined and an x-ray done. The doctors did not find any abnormality, so they said that it might be because of the pollution,” he says, adding, “One day when I came back from work, the pain had reached such an unbearable level and my family got so worried that I had to be hospitalised and kept under observation.”
