Colder and dirtier air in New Delhi has led to an increase in patients seeking medical treatment for respiratory issues such as wheezing, cough, chest discomfort, headache, fatigue, and insomnia. Doctors estimate a 40% rise in the daily influx of such patients, with cases of pneumonia, asthma, and COPD being admitted to hospitals. The spike in cases started in November when pollution levels were at their peak. Experts recommend taking flu and pneumonia vaccinations, practicing good hygiene, and maintaining a healthy lifestyle to alleviate and prevent respiratory problems.
