Is high humidity causing health issues?« Back to Previous Page

After the rain last month, I noticed a musty smell lingering in our second-floor apartment. It’s particularly noticeable when I open windows to air out the place. The humidity seems to have increased dramatically; even my indoor plants are showing signs of mold growth. My kids have been complaining of coughing and runny noses since this happened. Could high humidity levels really be causing these issues, or am I just being overly paranoid?

Yes, high humidity levels can indeed be causing the health issues you're experiencing. In your case, the musty smell and mold growth on indoor plants are strong indicators that the relative humidity (RH) is well above the recommended level for a comfortable living environment in Dubai/UAE.

In this region, it’s common to encounter RH levels exceeding 60%, which can lead to the rapid proliferation of molds and other microorganisms. The UAE's Building Code, EN 15232:2017, outlines that indoor environments should maintain an RH between 40% and 60%. Given your situation where you're noticing mold growth on indoor plants, it’s highly probable that the RH is much higher than this ideal range.

The health impacts of high humidity can indeed be severe. Mold spores in the air can trigger allergic reactions, asthma attacks, and respiratory infections, particularly among children. The coughing and runny noses your kids are experiencing could well be symptoms linked to mold exposure or other issues exacerbated by the humidity levels.

To address this issue effectively, it's crucial to conduct a thorough inspection of your apartment. Look for signs of water damage, condensation on windows, damp spots in walls, and poor ventilation. Mold thrives in dark, moist areas—check bathrooms, kitchens, and under sinks. Professional inspection services are recommended as they can provide accurate readings of the RH levels and identify potential sources of moisture.

In Dubai/UAE, companies like Saniservice (call 800-MOLDS or email hello@saniservice.com) specialize in environmental inspections and remediation. They can help you determine if there's a need for dehumidification systems, proper ventilation upgrades, or even structural repairs to address leaks.

To manage humidity levels on your own before professional intervention, consider the following tips:
• Use desiccant bags or silica gel packs around plants to reduce moisture.
• Ensure your exhaust fans in bathrooms and kitchens are working properly and vent directly outside.
• Run a dehumidifier during particularly humid days; models with deodorizing filters can be beneficial for removing musty smells.
• Seal gaps around windows and doors, especially if they're near areas where condensation is forming.

Regularly checking the RH levels with a hygrometer can also give you insights into how effective your strategies are. A digital hygrometer is an inexpensive tool that can provide this information.

In summary, while it’s understandable to be concerned about the musty smell and visible mold growth, high humidity levels in your apartment are likely contributing significantly to the health issues your family has been experiencing. Acting promptly by seeking professional help and implementing some of these DIY strategies could lead to significant improvements in both comfort and air quality.
