Tackling triggers of asthma & bronchitis

By Dr Utkarsh Shah

Many patients report persistent cough and sneezing, often caused not by infection but by hidden household allergens present in their immediate surroundings daily. Allergic bronchitis arises when airways react to everyday triggers commonly found in Indian homes.

Dust & dust mites

Household dust is a leading trigger for bronchitis and asthma in India, as dust mites in bedding and furniture release particles that inflame the airways when inhaled.

• Wash bed sheets and pillowcases in hot water every week. Soaking bed sheets in water above 50 degrees kills dust mites.
• Use dust-mite-proof covers on mattresses and pillows
• Vacuum carpets and sofas twice a week; avoid heavy drapes
• Keep indoor humidity below 50%, use an exhaust fan in bathrooms and kitchen

Pollen

Pollen from grasses, trees, and crops, especially in peak seasons and early mornings, is a major trigger for respiratory issues.

• Keep windows closed during high-pollen mornings
• Wear a mask (N95 or 3-ply) when stepping outdoors in peak season
• Shower and change clothes after outdoor exposure

Mould & fungal spores

Damp, poorly ventilated spaces promote mould growth, and inhaling its spores can trigger bronchitis and worsen asthma.

• Fix water leaks and seepage immediately
• Ensure good ventilation in kitchen, bathroom, and storage areas
• Discard old, stored food grains showing white patches or bad smell

Smoke & indoor pollutants

Household smoke from chillahs, coils, incense, and tobacco can irritate airways, trigger respiratory problems.

• Shift to LPG or induction cooking; ensure kitchen exhaust
• Avoid burning mosquito coils indoors; use liquid vaporizers instead
• Maintain a strict no-smoking policy inside the home

Preventive steps for every home

• Use air purifiers with HEPA filters in bedrooms, especially for children
• Wear N95 masks during construction, Diwali crackers, or dusty weather
• Keep pets out of bedrooms — pet dander is a strong allergen
• Nasal saline rinse or saline drops daily during allergy season
• Do not self-medicate with cough syrups — consult your physician for the correct diagnosis
