Is black mold in bedroom causing our cough and runny nose?« Back to Previous Page

The black mold you've described, especially with the accompanying dampness, is a likely contributor to your husband's respiratory symptoms. Many molds produce irritants and allergens that cause exactly these issues—persistent cough, runny nose, and congestion. In Dubai's climate, this is a common problem; high external humidity can lead to condensation on cooler interior walls, particularly in closets or behind furniture where air circulation is poor.

You should prioritize addressing the moisture source immediately. For a small patch (under one square foot), you can clean it yourself with a vinegar solution. However, since the wall feels damp, the issue is likely inside the wall cavity, which requires professional assessment to find and rectify the leak or condensation point. Simply cleaning the surface mold will not solve the problem if the hidden moisture remains.

Given the symptoms, a visit to a doctor is advisable to rule out other causes and get treatment for the irritation. For the mold itself, a professional inspection is recommended to determine the extent. They can use moisture meters and thermal imaging to find the hidden dampness. A lab test can identify the mold species, which is the only way to confirm its type and potential health risks, though any visible mold with dampness should be remediated. Companies with their own microbiology labs can provide this specific identification. The key is to fix the water issue first; otherwise, the mold will return.
