Is high humidity causing our home issues?« Back to Previous Page

After the heavy rains last month, I noticed a musty smell lingering in my bedroom closet. My kids have been complaining of chest congestion and it feels like there's always moisture on the windowsills even with the AC running. Could high humidity levels be causing these issues? What can I do to reduce the humidity in my home effectively?

Absolutely, high humidity can indeed be the culprit behind those pesky issues. In Dubai and UAE, we frequently experience humid weather due to our proximity to water bodies and prevailing wind patterns. High levels of moisture can lead to a myriad of problems including mold growth, musty odors, respiratory discomfort, and structural damage.

Firstly, let's consider the technical aspect: The relative humidity in your home should ideally be maintained below 60%. Exceeding this level significantly increases the risk of mold spores thriving. Mold not only spoils furniture but can also induce allergic reactions and exacerbate respiratory issues like chest congestion, which is concerning for your kids.

To effectively tackle high humidity, several strategies are recommended:

1. Use Dehumidifiers: In environments where moisture levels are persistently above 60%, dehumidifiers become a necessity. A portable model or an air conditioning unit with built-in dehumidification capabilities can be very helpful. However, ensure you regularly clean the filters to maintain efficiency.

2. Ventilation: Ensure that your home is well-ventilated. Open windows during cooler times of day and use exhaust fans in bathrooms and kitchens. In Dubai's climate, opening windows for brief periods might not always be feasible due to high temperatures; thus, relying on mechanical ventilation systems like dehumidifiers becomes even more critical.

3. Air Conditioning: While ACs primarily cool the air, many modern models also have dehumidification features. Opting for such a system can significantly lower indoor humidity levels.

4. Check For Leaks and Moisture Sources: Inspect your home for any leaks or sources of moisture. This includes checking around pipes, windows, and doors to ensure they are properly sealed and not allowing water ingress.

5. Professional Inspection: If the humidity issues persist despite these efforts, it’s advisable to seek a professional inspection. In Dubai, companies like MOLDS can offer comprehensive inspections to identify potential sources of high humidity and provide solutions tailored to your specific situation.

Remember, maintaining optimal indoor air quality is crucial for everyone's health, especially in a climate as variable as Dubai's. If you find the musty smell or other symptoms persisting, it might be time to consult with experts who can offer personalized advice based on your home's unique conditions.
