The cooler breezes and rainshowers of the monsoon season may bring much-needed relief from the summer heat, but they also come with a rise in infections and allergies. One of the most common and often ignored problems during this time is a persistent cough. While it’s common to dismiss a cough as part of seasonal change, doctors say that if your cough lasts more than 2–3 weeks, it could point to an underlying health issue that needs attention.
Why does your cough linger in the monsoon?
“The increased moisture in the air during the monsoon creates the perfect environment for allergens like mould to grow, especially indoors,” explains Dr. Ankit Kumar Sinha, Senior Consultant and Unit Head – Pulmonology, Respiratory and Sleep Medicine, Max Super Speciality Hospital, Vaishali. “People with a history of respiratory problems, allergies, or smoking may find their symptoms worsen during this season.”
Humidity and poor air circulation can irritate the airways, leading to coughing, wheezing, or shortness of breath. But according to Dr. Sinha, there could be several reasons why your cough is not going away.
1. Allergic bronchitis or asthma
“Monsoon humidity can act as a trigger for people with asthma or allergic bronchitis,” says Dr. Sinha. “If you’re coughing frequently, have wheezing or feel breathless, especially if you have a history of allergies or dust sensitivity, these could be signs.”
In such cases, it’s important to get evaluated and avoid self-medicating with over-the-counter cough syrups.
2. Post-viral cough
If you recently had a cold or flu, but your cough continues weeks after the infection has passed, you could be dealing with a post-viral cough.
“This is quite common and can linger for up to 6–8 weeks,” says Dr. Sinha. “It isn’t usually dangerous, but it can affect daily life. Inhalers or mild anti-inflammatory treatment might help,” he further said.
3. Undiagnosed sinusitis
A persistent cough that gets worse at night could be due to post-nasal drip, where mucus from the sinuses drips into the throat, triggering a cough.
“Monsoon season increases the chances of nasal congestion and sinus infections. If you’re constantly clearing your throat or coughing when lying down, it might be due to sinusitis,” he explains. “It’s often underdiagnosed but very treatable.”
4. Tuberculosis or lower respiratory infection
A cough lasting beyond 2–3 weeks with symptoms like mild fever, fatigue, weight loss, or blood in the sputum can be a red flag for something serious.
“Tuberculosis (TB) remains a significant health concern in India,” warns Dr. Sinha. “A lingering cough with additional symptoms should never be ignored. Early detection and treatment are crucial.”
Other lower respiratory infections like bronchitis or pneumonia can also present with similar symptoms and need medical evaluation.
5. Acid reflux (Gastroesophageal Reflux Disease or GERD)
One of the more surprising causes of a long-term dry cough is acid reflux.
“If your cough worsens at night or after meals, GERD could be the reason,” says Dr. Sinha. “It doesn’t cause the usual cold or chest symptoms, which is why many people don’t suspect it,” he said.
When should you see a doctor?
Dr. Sinha advises that it’s time to visit a doctor if:
- Your cough lasts more than 2–3 weeks
- You’re also experiencing wheezing, chest pain, or fever
- There’s blood in your sputum
- You feel unusually tired or are losing weight without trying
“A lingering cough isn’t always harmless,” he says. “If it’s not going away, don’t wait. Getting it checked early can lead to quicker recovery and prevent complications.”
So the next time your monsoon cough refuses to go away, don’t ignore it. Listen to your body and seek timely care.
