Mold and dust mites silently attack the respiratory tract.
According to Dr. Nguyen Huu Truong, Deputy Director of the Clinical Allergy and Immunology Center at Bach Mai Hospital ( Hanoi ), the alternating dry and humid weather creates favorable conditions for mold and dust mites to thrive, especially in enclosed spaces where air conditioning is frequently used.
Experts note four common irritants that can irritate the respiratory tract: mold, dust mites, pollen, and pet dander. Mold, in particular, can grow on air conditioner filters, in corners, under furniture, or in areas that are frequently damp. Mold spores are released into the air and then carried throughout the room by the air conditioner's airflow.
