The arrival of the monsoon brings relief from the summer heat, but it also increases the risk of respiratory illnesses, including pneumonia. Health experts warn that high humidity, damp indoor environments and the rapid spread of bacteria and viruses during the rainy season make lung infections more common.

According to the SWORD multicentre study (2022), respiratory tract infections account for nearly 13% of illnesses during the monsoon, compared with around 4% during the summer months. Medical experts also note that remaining in wet clothes for prolonged periods after getting drenched can increase the risk of respiratory infections that may develop into pneumonia.

What Is Pneumonia?

Pneumonia is a serious lung infection that causes inflammation in the air sacs of the lungs, which may fill with fluid or pus. It can be caused by bacteria, viruses or fungi and may develop after untreated flu, cold or other respiratory infections.

Who Is Most at Risk?

Doctors say pneumonia is more likely to affect:

• Children under five years of age
• Senior citizens
• People with weakened immunity
• Individuals with chronic lung diseases such as asthma or COPD
• Smokers
• People with diabetes or other chronic illnesses

Early Warning Signs

Early symptoms often resemble a common cold but become more severe over time. Watch for:

• Persistent cough
• High fever
• Difficulty breathing
• Chest pain
• Fatigue and weakness
• Chills
• Low oxygen levels

In children, danger signs include rapid breathing, chest retractions, refusal to eat or drink, persistent vomiting and bluish lips or nails. These symptoms require immediate medical attention.

Can Monsoon Conditions Trigger Pneumonia?

Doctors explain that getting wet in the rain does not directly cause pneumonia. However, remaining in wet clothes for extended periods, exposure to damp surroundings, mould and poor ventilation can increase the risk of infections. Dirty air conditioners and fungal growth inside homes may also aggravate respiratory problems, particularly in people with weak immunity.

11 Ways to Prevent Pneumonia During Monsoon

Health experts recommend the following precautions:

1. Keep homes dry and free from dampness and mould.
2. Ensure proper ventilation indoors.
3. Change into dry clothes immediately after getting wet.
4. Avoid smoking and secondhand smoke.
5. Minimise exposure to dust, pollution and smoke.
6. Stay well hydrated.
7. Eat a balanced diet rich in fruits, vegetables and protein.
8. Exercise regularly and practise breathing exercises.
9. Do not ignore persistent cough, fever or breathlessness.
10. Get flu and pneumococcal vaccines if advised by your doctor.
11. Get adequate sleep and manage stress to strengthen immunity.

When Should You See a Doctor?

Seek immediate medical care if you experience severe breathlessness, persistent high fever, chest pain, low oxygen levels or worsening symptoms. Early diagnosis and timely treatment significantly reduce the risk of serious complications.

Doctors advise that while many respiratory infections are mild, pneumonia can become life-threatening if left untreated, making early medical consultation essential during the monsoon season.
