Could bedroom mold be causing our persistent cough?« Back to Previous Page

Yes, the black mould behind your curtain is very likely the cause of your family's persistent cough and fatigue. In Dubai's high humidity, AC units are a common source of condensation, creating the damp environment mould needs to thrive. The continuous inhalation of mould spores and mycotoxins released into the bedroom air is a well-documented irritant, leading to chronic coughing, congestion, and a general feeling of unwellness, especially in children.

For a case of this visible size and with ongoing health symptoms, a professional inspection is strongly advised. They will identify the exact species (like Stachybotrys, which is often black and wet) and the full extent of the growth, which can spread inside wall cavities. Remediation involves more than just wiping the wall; the AC drip line must be corrected to prevent immediate recurrence, and any damaged drywall may need replacement.

In the UAE, companies specialising in this should follow guidelines like the IICRC S520 standard for mould remediation. The process includes containment of the area, HEPA-filtered air scrubbing, and proper disposal of contaminated materials. After remediation, a clearance test—typically an air quality sample analysed by an independent microbiology lab—is the only way to verify the space is truly safe and the spore count has returned to normal background levels.
