Is high humidity causing mold growth?« Back to Previous Page

After the heavy rains we had last month, I noticed a persistent musty smell in my bedroom closet. The area doesn't get much air circulation, and now both my son and daughter are complaining of coughs and runny noses. Could this be due to high humidity levels? What can I do to address this issue before it gets worse for the whole family?

Absolutely, high humidity levels can indeed contribute to mold growth. In the context of the UAE and Dubai specifically, humidity levels are naturally higher during certain periods due to the geographical location. The recent heavy rains have exacerbated this issue, potentially creating a perfect environment for moisture accumulation in areas like your bedroom closet.

Mold spores thrive when relative humidity exceeds 70%. Since you've noticed persistent musty smells and respiratory issues among family members, it’s highly probable that high humidity is at the root of these problems. Mold not only produces unpleasant odors but can also lead to significant health concerns such as allergic reactions, asthma attacks, and in severe cases, respiratory infections.

Given your situation, it would be prudent to take immediate steps to mitigate moisture levels and prevent further mold growth:

1. Ventilation: Enhance air circulation by using exhaust fans or dehumidifiers, especially in areas prone to high humidity such as the bedroom closet. Ensure that windows are opened briefly during cooler parts of the day if weather conditions permit.

2. Dehumidification Equipment: Consider purchasing a portable dehumidifier suitable for your room size. Aim for models with a capacity of at least 30-40 liters per day, depending on the square footage and humidity levels in your space.

3. Inspection by Professionals: Given the UAE's stringent building regulations regarding indoor air quality (particularly under the Building Control Law No. 29 of 2018), it might be wise to consult with a professional environmental inspection company like Saniservice. They can conduct thorough assessments and provide expert recommendations tailored for your specific environment.

4. Surface Cleaning: Regularly clean and dry any surfaces that may have been exposed to moisture or condensation. Use a mixture of water and detergent, then dry thoroughly to prevent mold from establishing itself.

5. Seal Off Moisture Sources: Identify and seal off sources of excess moisture. This could include repairing leaky pipes, ensuring proper drainage around your house, and sealing gaps in the structure where water might seep through.

6. Consultation with Healthcare Providers: Given that family members are experiencing coughs and runny noses, it’s advisable to consult a healthcare provider for appropriate treatment and advice on managing any potential health issues related to mold exposure.

Remember, proactive measures can significantly reduce the risk of mold growth and improve indoor air quality, ensuring a healthier living environment. Should you find the situation worsening or needing more immediate attention, don't hesitate to contact Saniservice at 800-MOLDS (800-66537) or via email at hello@saniservice.com for prompt assistance.

By taking these steps, you can effectively manage and reduce humidity levels in your home, thereby mitigating the risk of mold growth and promoting a healthier living environment.
