Is mold causing my headaches and sinus issues?« Back to Previous Page

Yes, the mold growth from your AC leak is very likely causing your sinus issues and headaches. The constant dampness from the leak creates an ideal environment for mold spores to proliferate, and your proximity to it while sleeping means you're exposed for hours. The black and green coloration suggests a mix of species, some of which are known irritants.

In Dubai's climate, AC units are a primary source of indoor condensation and subsequent mold if not maintained. The high humidity outside means systems work hard, and any leak inside a cooled room creates a significant moisture problem. The symptoms you describe—morning congestion and persistent headaches—are classic signs of mold exposure, even from non-toxic species, due to the inflammatory response they trigger.

You are not overreacting. The first step is to stop the source of moisture. Have an HVAC technician repair the AC leak immediately. For the existing growth, do not attempt to clean it yourself, as this can aerosolize spores. A professional inspection is recommended to assess the extent of the growth, especially within the wall cavity behind the headboard, which may be more severe than what's visible. They can perform surface and air testing to identify the mold types present. In many cases, remediation involves controlled removal of affected materials and HEPA vacuuming to properly resolve the issue and your symptoms.
