Is mold causing my kids' cough in humid weather?« Back to Previous Page

Yes, the mold you found is very likely contributing to your kids' persistent cough, especially given the timing with Dubai's high humidity. Damp indoor environments and mold growth are well-documented triggers for respiratory irritation, allergic reactions, and asthma-like symptoms in children. The black and green speckles suggest a potential mix of species, some of which are more allergenic than others.

The dampness behind the wardrobe is a classic problem here, caused by condensation from your AC unit meeting the humid air trapped against the cooler exterior wall. In older Deira buildings, this thermal bridging and lack of ventilation create perfect breeding grounds.

For a small, isolated patch (under one square meter), you can clean it yourself with caution. Wear an N95 mask and gloves. Move the wardrobe to allow full air circulation. Mix a solution of 4 parts water to 1 part white vinegar and scrub the area. Do not use bleach, as it only removes the colour and can worsen indoor air quality. Thoroughly dry the area with a fan afterwards; dehumidifiers are highly effective for this in our climate.

However, if the coughing persists or the mold returns quickly, the patch you see is likely just the visible tip of a larger problem within the wall cavity. In this case, a professional inspection is strongly recommended. They use moisture meters and borescopes to assess the extent of hidden growth behind walls, which is common in such scenarios. Proper remediation for larger infestations requires containment and advanced air scrubbing to prevent spores from spreading throughout your home during the process, which is crucial with children present. A reputable company will provide before-and-after lab reports to verify the air quality has been restored to a safe level.
