The alarmingly high air quality index (AQI) in India's northern region, particularly in Delhi, has created a suffocating environment for residents. This toxic air has led to a surge in respiratory issues, with persistent cough, itchy eyes, runny nose, fever, and frequent sneezing becoming common complaints. While many attribute these symptoms to viral infections, doctors are observing a significant increase in patients presenting with cough and cold-like symptoms despite testing negative for bacterial or viral pathogens.
Dr. Neetu Jain, a pulmonologist at PSRI Hospital in New Delhi, reports that over half of the patients visiting her OPD exhibit cough-like symptoms. She explains that the excessive particulate matter and pollutants present in the air inflame the airways, leading to bronchial hyperactivity. This narrowing of the airways mimics the symptoms of asthma, resulting in a persistent cough that often resists traditional remedies like cough syrups or home treatments.
The prolonged nature of this pollution-induced cough is a cause for concern. Dr. Jain highlights that heavy smokers, especially those with no prior history of coughing, should be particularly vigilant. They may experience exacerbated symptoms due to air pollution, warranting immediate medical attention if the cough persists for more than a week. She also notes a rise in hospital admissions related to tuberculosis and pneumonia, emphasizing the importance of wearing N95 masks when venturing outdoors to protect the lungs from infection.
A persistent cough can be addressed through various methods, including nebulizers, SOS inhalers, and prescribed medications designed to open the airways. The article also delves into the science behind coughing, explaining that it's a natural bodily reflex triggered by irritants like germs, dust, and mucus. While occasional coughing is normal, prolonged coughing or the presence of discolored or bloody mucus warrants immediate medical attention as it could signal an underlying medical condition.
In conclusion, the article emphasizes the significant health risks associated with Delhi's toxic air, particularly the prevalence of persistent coughs that are not necessarily caused by infections. It urges individuals to take these coughs seriously and seek medical advice if symptoms persist. Additionally, the article advocates for wearing N95 masks as a protective measure against air pollution and associated health risks.
