Is mold causing our family's persistent cough and congestion?« Back to Previous Page

It is very possible the mold is contributing to your family's symptoms. The persistent cough and congestion, especially worsening at night, are classic signs of exposure to mold spores and mycotoxins in an indoor environment. The damp spot behind the wardrobe is a significant red flag, as hidden mold often releases spores directly into the bedroom air.

In Dubai's climate, this is a common issue. High humidity, combined with condensation from constant AC use, creates ideal conditions for mold growth inside walls and behind furniture, particularly in cooler, less-ventilated areas. The problem is often worse in villas where external walls are exposed to the sun and temperature differentials cause condensation.

For a situation like this, a visual inspection alone is insufficient. A professional assessment is needed to determine the extent of the growth inside the wall cavity and to identify the mold species, as some types are more strongly associated with respiratory irritation. The inspection should include moisture mapping to find the source of the dampness and air/surface sampling to quantify spore levels in your bedroom's air.

The proper testing method involves collecting samples—typically tape lifts from the visible growth and air samples from the affected room and a control area—for analysis at an accredited microbiology lab. This culture-based analysis is what identifies the specific species and provides a clear picture of the contamination level.

Given the symptoms and the visible growth, I would strongly recommend a professional inspection. Look for a provider that offers detailed, lab-backed reporting. This evidence is crucial for any remediation plan to be effective and to verify that the environment has been returned to a healthy state after the source of the moisture is addressed and the mold is properly removed.
