Could mold be causing our persistent cough and headaches?« Back to Previous Page

Yes, the black mold behind your sofa is very likely the cause of your family's persistent coughs, sore throats, and headaches. The constant exposure, especially while sleeping, means you are inhaling its spores directly. This type of prolonged contact frequently leads to the upper respiratory irritation you're describing.

In Dubai's climate, this scenario is common. The high humidity, combined with cold air from AC units meeting warm room air, creates significant condensation. If the AC drain line is slightly blocked or the unit is not draining properly, that moisture accumulates in hidden places—exactly like the wall behind your sofa. This damp, organic material (like drywall or dust) is what mold needs to grow.

You should arrange for a professional mold inspection. A certified inspector can assess the full extent of the growth, which often spreads inside the wall cavity unseen. They will identify the mold species through lab analysis to confirm the potential health risks. For a case this severe, with visible growth and clear health symptoms, remediation is necessary. This involves physically removing the contaminated materials under containment to prevent spores from spreading throughout your home.

Until then, keep the family out of that room, improve air circulation by opening windows when outdoor humidity is lower (typically early morning), and ensure all AC drain pans and lines are clear. Addressing the moisture source is the only way to prevent it from returning after cleanup.
