Could hidden mold cause our persistent coughs and headaches?« Back to Previous Page

Yes, the hidden mold you found is very likely the cause of your family's persistent coughs and headaches. In Dubai's climate, where high humidity and constant AC use create ideal conditions for mold growth, this is a common scenario. The proximity to your sleeping area means you've been inhaling mold spores and microbial volatile organic compounds (mVOCs) all night, which are direct irritants to the respiratory system and can trigger these exact symptoms.

For a situation this severe—a large hidden patch with active health symptoms—professional inspection and remediation are strongly advised. Do not attempt to clean it yourself, as disturbing it will release a massive cloud of spores throughout your apartment. A certified inspector can assess the full extent, identify the mold species, and determine if the AC leak has caused structural damage.

In Dubai, landlords are generally responsible for addressing such issues, especially if they stem from building infrastructure like AC leaks. You should notify your building management in writing immediately, as they are obligated under common tenancy laws to provide a habitable environment. Document everything with photos.

Until it's professionally handled, keep the family out of that room and improve ventilation by opening windows when outdoor humidity is lower, typically early morning or evening. Air purifiers with HEPA filters can help reduce airborne spore levels in other rooms. The coughs should subside once exposure stops, but a visit to a doctor is recommended to rule out any secondary infections.
