Can high humidity cause mold and health issues?« Back to Previous Page

After the heavy rains we had last month, I noticed a persistent musty smell coming from the bottom of my bedroom closet. The AC in my apartment seems to struggle, even when it’s on high, but the humidity still feels really high, especially at night. My kids have been complaining about coughing more lately, and I’m starting to think it might be related. Do you think this is something that can be managed with some DIY solutions or should we consider professional help?

High humidity can indeed lead to the growth of mold and pose significant health risks, especially in environments like Dubai's climate. The persistent musty smell from your closet combined with increased coughing symptoms among family members could indicate a high moisture environment conducive for mold proliferation.

Molds thrive in conditions where the relative humidity is above 60%. Given that you're experiencing high humidity even when the air conditioning system runs, it suggests there might be underlying issues such as water intrusion or inadequate ventilation. In Dubai and other hot-humid environments, these conditions can quickly facilitate mold growth on various surfaces like wood, carpets, and fabrics.

From a practical perspective, managing high indoor humidity levels is crucial to prevent health issues associated with mold exposure. The UAE's Building Code does not specify exact thresholds for indoor relative humidity but recommends maintaining it below 60% to reduce the risk of condensation and subsequent microbial growth. However, achieving this level in your environment might require targeted measures.

To mitigate these issues, you could start by improving ventilation, using dehumidifiers, or installing moisture barriers if there are areas prone to water seepage. Regularly inspecting for signs of water damage or mold, such as discolored walls or peeling paint, is important. Addressing any plumbing leaks and ensuring proper drainage around the building can also help.

However, given that your air conditioning system seems inefficient in reducing humidity levels, it may be wise to consider professional inspection and remediation services. Companies operating under regulations like the UAE's Federal Institute of Real Estate (FIRE) and adhering to ASHRAE standards would provide reliable assessments and solutions tailored for high-humidity climates.

If you suspect mold or its health impacts on your family, don’t hesitate to contact professionals who can conduct thorough inspections and offer remediation services. Remember, early intervention is key in preventing further damage and ensuring the safety of your home environment.
