Is black mold and high humidity dangerous in Dubai?« Back to Previous Page

Yes, the presence of black mould and persistently high humidity is absolutely a serious health and structural concern here in Dubai. The symptoms you describe—stuffy nose, skin dampness, and a persistent cough—are classic indicators of poor indoor air quality caused by elevated moisture levels.

The UAE's hot and humid climate forces AC systems to work tirelessly to remove moisture from the air. If your unit is undersized, poorly maintained, or has a faulty dehumidification cycle, it will cool the air but leave the humidity behind, creating the exact conditions mould needs to thrive. The mould in your closet is a clear sign that the relative humidity in that enclosed space is far above the recommended 40-60% range. Prolonged exposure to mould spores can exacerbate respiratory issues like asthma, cause allergic reactions, and lead to chronic sinusitis.

For a temporary fix, ensure your AC unit is set to "Dry Mode" or a lower temperature (around 22-23°C) to encourage more moisture removal. Improve air circulation by using ceiling fans and never overcrowding closets. However, based on your description of constant AC operation and visible mould growth, these are likely insufficient.

The most effective solution requires a professional assessment. A dedicated dehumidifier is a powerful tool, but it only treats the symptom. The root cause could be a failing AC unit, inadequate insulation in that exterior wall (a common issue here), or even a minor plumbing leak pressurizing the wall cavity.

We strongly recommend a comprehensive indoor environmental inspection. Our certified technicians use thermal imaging and precise moisture meters to identify the exact source of the humidity and develop a targeted remediation plan, which includes safe mould removal.
