Asthma (bronchial asthma) is a chronic inflammatory disease of the respiratory tract. Doctor Nguyen Van Ngan from the Respiratory Unit at Tam Anh Cau Giay General Clinic explains that when exposed to irritants, the airways of asthma patients become inflamed, constrict, and produce excess mucus, leading to shortness of breath, wheezing, coughing, and chest tightness.

Dust mites

Dust mites are found in mattresses, pillows, bedding, and carpets. They feed on human skin cells and release waste products that strongly irritate the respiratory tract. Symptoms often worsen at night or in the early morning.

Solution: Regularly vacuum bedding, mattresses, and carpets. Wash them weekly with hot water above 60 degrees Celsius.

Pet fur and dander

Pet fur, dander, and saliva contain proteins that cause strong allergic reactions. These particles cling to furniture and clothing, remaining in the home for extended periods.

Solution: Keep pets out of bedrooms. Bathe and brush them regularly.

Incense smoke

Burning incense releases a large amount of fine particles, potentially more than cigarette smoke. This is often an overlooked trigger in many homes.

Solution: When burning incense, open windows for strong ventilation or burn it only for short durations.

Detergent residue, fabric softener

Detergents and fabric softeners leave a thin layer of chemical residue on clothes, which can then mix with dust and become a respiratory irritant when inhaled.

Solution: Choose low-chemical, unscented detergents. Rinse clothes an extra time during washing and dry them in the sun to reduce chemical exposure.

Mold

Mold thrives in damp areas like bathrooms, kitchens, leaky walls, and uncleaned air conditioners. Mold spores spread through the air and are a significant cause of asthma.

Solution: Maintain indoor humidity below 50%. Repair leaks promptly. Clean air conditioners and washing machines regularly, ensuring good ventilation.

Insects, mice

Feces, saliva, and carcasses from cockroaches and mice contain strong allergens. When cleaning, these particles can easily become airborne, triggering asthma attacks if inhaled by sufferers.

Solution: Maintain home hygiene to prevent insects and mice from nesting.

Chemicals, artificial fragrances

Floor cleaners, air fresheners, perfumes, wall paints, strong detergents, and similar products may contain volatile compounds that irritate the respiratory lining, especially in asthma patients.

Solution: Prioritize unscented or natural products. Ensure good ventilation when cleaning. Limit the use of air fresheners and scented candles in enclosed spaces.

Doctor Ngan states that asthma can be well-controlled by reducing trigger exposure. Keep your home clean, well-ventilated, reduce humidity, and limit the use of strong chemicals. Individuals who frequently experience coughing, wheezing, or shortness of breath, especially at night or when indoors, should seek examination and timely treatment at reputable medical facilities.
