Could bedroom mold cause our persistent coughing?« Back to Previous Page

Yes, that small patch of mold is a very likely culprit for the persistent coughing, especially in children. The visible mold is often just the tip of the iceberg; it indicates a moisture problem within the wall cavity, likely from the adjacent bathroom. In Dubai's high humidity, this allows mold colonies to grow and release microscopic spores into the bedroom air you're all breathing.

The constant AC use, while cooling, can also contribute by creating condensation if not properly maintained, further feeding hidden mold growth. Children are particularly susceptible as their respiratory systems are still developing. The coughing is a common reaction to inhaling these irritants.

You should arrange for a professional indoor environmental assessment. A proper inspection uses moisture meters and borescopes to check inside the wall for the true extent of the growth. Air and surface sampling sent to an accredited microbiology lab will identify the specific mold species present, which is critical for understanding the health risk and planning the correct remediation strategy. Do not attempt to clean it yourself with bleach, as this can aerosolize the spores and worsen the problem. The underlying moisture issue must be identified and fixed first to prevent it from returning.
