Could black mold in our bedroom cause our persistent cough?« Back to Previous Page

Yes, the black mold you found is very likely the cause of your family's persistent cough and sinus headaches. This is a common scenario in Dubai, where continuous AC use creates condensation that, if a unit has a slow leak, provides the constant moisture mold needs to thrive indoors. The spores released by active colonies are respiratory irritants, leading to exactly the symptoms you describe.

For a patch you describe as "huge," professional remediation is strongly advised for safety. Disturbing it during a DIY clean can aerosolize a massive amount of spores, worsening your exposure. The process requires more than just wiping it away; it involves containment of the area, use of HEPA filtration to capture spores, and the identification and repair of the moisture source—in this case, the leaking AC unit.

In Dubai, look for a provider that follows international guidelines like IICRC S520 and can provide verifiable proof of remediation, typically through before-and-after lab reports. This ensures the mold is properly removed, not just superficially cleaned. After remediation, a professional assessment of your AC system is essential to fix the leak and prevent the problem from immediately recurring. Addressing the root cause is the only way to achieve a long-term solution.
