Could bedroom mold cause my husband's cough and stuffy nose?« Back to Previous Page

Yes, the mold in your bedroom closet is very likely the cause of your husband's symptoms. The pattern of waking up with a stuffy nose and dry cough that improves after leaving the room is a classic indicator of mold exposure. These are common reactions to inhaling mold spores and mycotoxins released into the air, especially over several hours of sleep in a confined space.

In Dubai's climate, this scenario is common. High outdoor humidity, combined with year-round air conditioning, creates significant temperature differentials. Cold walls from AC can cause condensation to form in less-ventilated areas like closets, especially when they are packed with clothes that restrict airflow. This trapped moisture is a perfect breeding ground for mold.

You should address this promptly. Start by moving all clothing and items away from the affected corner to allow the area to dry completely. Wipe down the visible mold with a microfiber cloth and a solution of diluted white vinegar, but be aware this only addresses surface growth. The mold may have penetrated the wall material itself if the dampness has been ongoing.

For a case like this, a professional inspection is recommended to determine the extent of the problem behind the surface and identify the mold species. Some types, like Aspergillus, are more commonly associated with respiratory issues and are frequently identified in humid environments here. Remediation often requires removing affected porous materials, treating the area with antimicrobial solutions, and identifying and correcting the source of moisture, which is crucial for preventing a rapid recurrence.
