Could mold behind my sofa cause chronic coughing?« Back to Previous Page

Yes, the black mold behind your sofa is very likely the cause of your children's chronic coughing. In Dubai's high humidity, especially during summer, this is a common scenario. The wall corner where your AC unit is located is a prime spot for condensation to form and mold to grow, as cool indoor air meets the warm exterior wall. The fuzzy black growth you describe is actively releasing spores into the air your family breathes, which are a known respiratory irritant.

For children, whose airways are smaller and immune systems are still developing, exposure to this concentrated mold can trigger persistent coughing, wheezing, and allergy-like symptoms. The constant AC use here means the spores are being circulated throughout the room continuously.

Your first step is to isolate the area. Keep the sofa pulled away and restrict access to that part of the room. Do not attempt to clean it yourself with bleach, as improper disturbance will aerosolize a massive amount of spores and can make the situation worse.

This requires professional assessment. The specific type of mold needs to be identified through lab analysis to understand the health risk, as some species are more problematic than others. A proper inspection will also find the moisture source—whether it's a condensate drain leak from the AC unit, poor insulation, or seepage—and prescribe the correct remediation protocol to fix the problem permanently, not just remove the visible growth. Given the symptoms and the extent you describe, a certified mold inspection and subsequent water damage restoration are strongly advised.
