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

After the heavy rains last month, I noticed a musty smell in my bedroom closet. My kids have been complaining of persistent coughs and sniffles, and it feels like there's always moisture on the walls. Could this be due to high humidity levels? What can we do to address the issue before it affects our health further?

High humidity levels could very well be contributing to the musty smell and your family's respiratory issues. In Dubai, particularly after heavy rains, high indoor relative humidity (RH) often leads to mold growth, which can trigger allergic reactions, coughs, and sniffles in individuals.

The UAE has strict guidelines regarding indoor air quality, especially within residential buildings. The Building Control Regulations 2019 mandate that the RH inside a building should not exceed 65% during non-air-conditioned hours (usually between 7:00 PM to 8:00 AM) and no more than 55% during air-conditioned times. Your current situation, with persistent moisture on walls and family health issues, suggests that the humidity levels might be above these recommended values.

To effectively address this issue, it's advisable to first conduct a professional inspection by contacting Saniservice at 800-MOLDS or email hello@saniservice.com. This will help identify the exact source of moisture and assess the extent of mold growth, if present. A certified specialist can also provide a comprehensive plan for remediation.

In the meantime, there are steps you can take to lower humidity levels:

1. Use dehumidifiers: In rooms where high RH is detected, installing portable dehumidifiers can significantly reduce moisture content. Aim to maintain the air in these areas below 50% RH.
2. Proper ventilation: Ensure that bathrooms and kitchens have adequate exhaust fans to remove excess moisture from cooking and bathing activities. Open windows during non-air-conditioned times for natural ventilation.
3. Address leaks promptly: Any visible or hidden water leaks should be fixed immediately, as they can lead to mold growth.
4. Clean regularly: Dust, vacuum, and clean your home frequently using a HEPA filter vacuum cleaner which helps in removing spores and allergens from the air.

Remember, the key is maintaining consistent RH levels within acceptable ranges. Regular monitoring with an RH meter can help track progress and ensure long-term comfort and health for you and your family.
