Could bathtub mold cause my kids' persistent cough?« Back to Previous Page

Yes, bathtub mold is a very likely cause of your children's persistent cough. The hidden growth you discovered under the silicone sealant is a classic scenario in Dubai apartments, particularly in windowless bathrooms with poor ventilation. This type of damp, dark environment allows mold to thrive and release spores directly into the air your family breathes. These spores are a known respiratory irritant, especially for children, and can trigger chronic coughing, congestion, and worsened allergy symptoms.

The safest way to address this involves two steps: remediation and prevention. For the existing growth, simply wiping visible mold is insufficient, as the roots penetrate porous surfaces. The contaminated silicone sealant must be completely removed and replaced. This process should be done with containment to prevent spores from spreading to other parts of the apartment. Given the extent you've described and the health symptoms, a professional assessment is strongly recommended to ensure it is handled safely and thoroughly.

To prevent recurrence, you must address the source of moisture. A weak exhaust fan is a primary culprit. It should run during and for at least 20-30 minutes after every shower. Consider upgrading to a higher-capacity model. Consistently wiping down wet surfaces after use and using a squeegee on shower walls can also help. For a long-term solution, a professional can assess your bathroom's ventilation against Dubai Municipality standards and may suggest installing a positive pressure system or a dedicated dehumidifier to combat the high humidity.
