Could bathroom mold cause my kids' constant cough?« Back to Previous Page

Yes, bathroom mold is a very likely cause of your children's persistent cough, especially given the conditions you've described. The fuzzy black growth under the silicone is a classic sign of a significant moisture problem, and the spores it releases are a common indoor irritant. In Dubai's high humidity, bathrooms without adequate ventilation become perfect breeding grounds for mold, and the constant recirculation of air through your AC can distribute these spores throughout your apartment.

Children are particularly susceptible to mold-related health effects, which often present as cold-like respiratory symptoms—coughing, wheezing, nasal congestion, and throat irritation—that don't seem to resolve. Since you've already found visible, extensive growth, a professional inspection is strongly recommended to assess the full extent, as mold can often spread behind tiles and into wall cavities. Remediation involves properly removing the contaminated sealant and any affected materials, then treating the area with antimicrobial solutions to prevent regrowth.

For lasting results, address the source of humidity. Ensure your exhaust fan is powerful enough for the room size and that it runs for at least 30 minutes after each shower. Consider adding a portable dehumidifier. In many Dubai apartments, the problem is worsened by AC systems that recirculate damp air; having your AC unit and ducts inspected for mold is a critical next step to improve your entire apartment's air quality.
