Should I worry about closet mold affecting my child's health?« Back to Previous Page

Yes, you should take this seriously. The black spots along the carpet edge are a clear sign of moisture, likely from the adjacent bathroom. In Dubai's climate, high humidity and condensation from air conditioning create ideal conditions for mold growth in enclosed, poorly ventilated spaces like closets.

Your son's symptoms—a nighttime stuffy nose and cough that improves away from the bedroom—are classic indicators of mold exposure. Mold releases spores and microbial volatile organic compounds (mVOCs) that act as irritants, particularly in children whose respiratory systems are still developing. This is not necessarily a toxic mold situation, but consistent exposure to these irritants can exacerbate allergies and asthma.

You should schedule a visit with your pediatrician first to rule out other causes and discuss the symptoms. Concurrently, address the mold source. For a small, visible patch, a thorough cleaning with a vinegar or diluted detergent solution may suffice, but only after identifying and fixing the moisture issue, such as a leak under the bathroom vanity or insufficient sealing. However, given the location backing onto a bathroom and the associated health symptoms, a professional inspection is prudent to assess the extent of growth, especially what may be hidden beneath the carpet or in the wall cavity. They can perform air and surface sampling to identify the mold type and concentration, which provides a clear picture of the indoor air quality issue. Proper remediation focuses on removing the source of moisture and the affected materials to prevent recurrence.
