Could black mold cause our constant coughing and headaches?« Back to Previous Page

Yes, the black mold behind your sofa is very likely causing the coughing, headaches, and sore throats you're describing. Given your family has been sleeping right next to it for a month, this is a significant exposure.

In Dubai's high humidity, AC units are a common source of mold due to condensation leaks and dampness inside the ducts. The constant recirculation of air spreads mold spores throughout your apartment. The symptoms you list—persistent respiratory irritation and headaches—are classic signs of mold exposure, especially in children who are more sensitive. While not all black mold is the highly toxic Stachybotrys, many common species found in damp UAE homes can cause these health effects.

Your first step is to stop the moisture source. Turn off and repair the leaking AC unit immediately. Do not attempt to clean the large patch yourself, as disturbing it will release a massive amount of spores. For a growth of this size and given the health symptoms, a professional inspection and remediation is strongly advised. They will contain the area, safely remove the contaminated materials, and use HEPA filtration to clear the air. Afterwards, a post-remediation verification test, often conducted by a third-party lab, is the only way to confirm the spore count in your air has returned to a safe level. This is a critical step for peace of mind when children are involved.
