Smoke doesn’t disappear when a cigarette is put out. Harmful residues can remain on sofas, curtains, carpets, clothing, toys and other household surfaces—creating what is known as thirdhand smoke.

Children are especially vulnerable because of their developing lungs and frequent contact with contaminated surfaces. Protect your family by keeping your home and car completely smoke-free.

Waking up gasping for air is a warning sign that needs attention. It may be associated with asthma, sleep apnoea, heart problems or another respiratory condition.

Sit upright and follow your prescribed rescue plan, if you have one. If breathing is severely difficult, symptoms are worsening, or your rescue medication is not helping, seek emergency medical assistance immediately.

Chronic bronchitis and emphysema are both forms of COPD, but they affect the lungs differently.

Chronic bronchitis primarily involves inflammation, narrowing and excess mucus in the airways. Emphysema damages the tiny air sacs responsible for exchanging oxygen. Identifying the dominant pattern helps guide personalised treatment and symptom management.

A cough that lingers beyond two weeks shouldn’t be ignored. While it may follow a viral infection, a persistent or recurring cough can sometimes indicate ongoing airway inflammation or another underlying respiratory condition.

Consult a pulmonologist for proper evaluation especially if the cough is accompanied by breathlessness, wheezing, fever, chest pain or blood in the sputum.

Tuberculosis is curable when diagnosed early and treated correctly.

A cough lasting more than two weeks, unexplained weight loss, evening fever or night sweats should not be ignored. Consult a doctor, get tested and complete the entire prescribed course of treatment—never stop midway or self-medicate.

Monsoon brings welcome relief—but damp weather can also trigger mould growth and respiratory infections. 🌧️🫁

Keep indoor spaces dry and well-ventilated, and don’t ignore worsening cough, wheezing or breathlessness—especially if you have asthma or COPD. Early medical care can help protect your lungs.
