Rising Air Pollution Triggers Persistent Coughs in Children

Rising air pollution and changing weather are driving an increase in persistent coughs among children in Pune.

Key Clinical Takeaways:

• Children run a higher risk from air pollution than adults because their lungs are still developing and they breathe faster.
• Doctors warn parents not to ignore a cough that lingers, worsens, or keeps returning.
• Self-diagnosing with home remedies, cough syrups, or antibiotics can delay proper medical care.

Children face increased exposure to dust, smoke, vehicle emissions, and construction particulate matter. These pollutants irritate airways, trigger inflammation, and worsen underlying conditions like asthma and allergies.

Viral and bacterial infections can also cause fever, congestion, and breathing difficulties alongside the cough.

“Parents should not ignore a cough that persists, worsens or keeps returning in children,” said Dr. Tushar Parikh, Senior Consultant Neonatologist & Paediatrician at Motherhood Hospital in Kharadi, Pune.

Dr. Parikh said that pollution irritation often worsens after outdoor exposure or in areas with poor air quality. Viral coughs, by contrast, tend to improve gradually over time.

“However, if the child also develops fever, rapid breathing, chest discomfort, poor feeding or unusual tiredness, an underlying respiratory infection needs to be considered,” Dr. Parikh said. He added that pneumonia can begin with symptoms resembling a common cold.

Medical experts emphasize that parents must watch for specific red-flag symptoms that require immediate medical attention rather than a wait-and-see approach.

Warning signs include fast breathing, chest indrawing, bluish lips, difficulty speaking or feeding, and unusual drowsiness.

Prolonged coughing lasting more than two weeks also requires investigation for conditions like tuberculosis, which doctors diagnose using a chest X-ray and a few tests.

Adults in Pune are also experiencing respiratory distress as air quality deteriorates.

Dr. Sanjay Nagarkar, an Internal Medicine Expert at Apollo Spectra Hospital Pune, said that air pollution is directly affecting lung health. Over a recent 15-to-20-day window, approximately five to six adults aged 25 to 55 visited the outpatient department with persistent coughs, throat irritation, and breathing difficulties.

During the same period, three to four senior citizens over 60 and one to two children aged five to 10 sought care for similar symptoms.

“Repeated exposure to polluted air can lead to airway inflammation, worsen allergies, and also aggravate existing respiratory conditions like asthma and bronchitis,” Dr. Nagarkar said.

Healthcare providers advise families to check local air quality levels regularly and limit outdoor activities when pollution spikes.

Preventive steps include avoiding cigarette smoke exposure, keeping children up to date on recommended vaccinations, maintaining good hand hygiene, and encouraging adequate hydration.

“Checking local air quality levels, limiting outdoor activities when pollution levels are high, avoiding exposure to cigarette smoke, and ensuring children follow their recommended vaccination schedules,” Dr. Parikh said, listing key protective measures.
