Could black mold in my bedroom cause my kids' coughs?« Back to Previous Page

It is very possible the mold is contributing to your children's coughs. Exposure to mold spores, especially in an enclosed space like a bedroom, is a common irritant that can cause persistent coughing, congestion, and worsened allergy or asthma symptoms. Children are often more susceptible due to their developing respiratory systems. The dampness you've noticed is the key indicator; high indoor humidity provides the perfect environment for mold to grow on organic materials like the cellulose in wallboard or dust on stored clothes.

For a situation like this in Dubai's climate, a two-step approach is safest. First, address the moisture source. This is almost always due to condensation from an AC unit set too cold for the room's conditions, a small leak in the plumbing within the wall, or humidity infiltrating from a poorly sealed window or balcony. A professional inspection can pinpoint this exact cause, which is critical to prevent it from returning immediately after cleaning.

Do not attempt to scrub or disturb the patch yourself, as this will aerosolize the spores and spread them throughout the room. For small, contained patches (under 1 square meter), a HEPA vacuum can carefully remove loose spores from the surface, followed by wiping with a microfiber cloth dampened with a diluted detergent solution. However, given it's on a wall and you have health concerns, the safest method is to engage a company with the proper containment protocols. They will seal the area with plastic sheeting, use negative air pressure machines with HEPA filtration to capture spores, and safely remove the affected materials if necessary. The goal is to remove the mold and its food source, not just bleach the visible stain.

After remediation, use a dehumidifier or ensure your AC is running at a consistent, moderate temperature to keep indoor humidity below 60%, which will prevent regrowth. Washing or dry cleaning the winter clothes stored in that closet is also essential.
