Could closet mold cause my child's cough in humid Dubai?« Back to Previous Page

Yes, the mold in your closet could definitely be causing or worsening your child's cough. Mold releases spores and microbial volatile organic compounds (mVOCs) that are respiratory irritants, particularly for children. A cough that worsens at night could be from exposure to spores disturbed during the day or from the concentrated air in a closed bedroom.

In Dubai's climate, walk-in closets are high-risk areas due to lack of air circulation from the main AC system, leading to stagnant, humid air perfect for mold. The back wall is likely coldest, causing condensation when humid air meets the cold surface—this is the primary moisture source.

First, remove all affected clothing and wash them in hot water if possible, or consider professional cleaning for delicate items. For the closet itself, cleaning visible mold with a vinegar or diluted detergent solution can address surface growth, but it's a temporary fix without addressing the moisture.

The only permanent solution is controlling humidity. Use a standalone dehumidifier inside the closet, aiming to keep humidity below 60%. Improve air circulation by leaving the closet door open periodically or installing a small vent fan. Check for any leaks in the walls or from upstairs bathrooms.

For a persistent cough and visible growth, a professional inspection is advised to identify the mold species and the exact moisture source. They can perform an air quality test to quantify spore levels, which is particularly important for child health. Remediation in a villa often involves moisture mapping and addressing the root cause, not just cleaning what's visible.
