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

After the heavy rain last month, I noticed a musty smell lingering in the master bedroom, even after running the dehumidifier all day. My daughter has been complaining of stuffy nasal passages and coughing up clear mucus lately. The humidity levels seem to be skyrocketing despite our efforts to keep the windows closed. Is this normal for Dubai during rainy seasons, or could it be causing respiratory issues?

High humidity can indeed cause respiratory issues and it's not uncommon for such conditions to arise during the rainy seasons in Dubai. The increased moisture content in the air can lead to a proliferation of mold, dust mites, and other allergens that are known triggers for asthma and allergic rhinitis. In your case, the musty smell coupled with your daughter’s symptoms like stuffy nasal passages and clear mucus production suggest that high humidity might be the culprit.

The UAE, particularly Dubai, experiences significant fluctuations in humidity levels during various seasons. The rainy season, which typically falls between October and March, can exacerbate existing indoor environmental quality issues if not managed properly. According to local regulations, maintaining a relative humidity level of 60% or less is recommended to prevent the growth of mold and other microorganisms that thrive in damp conditions.

Given your situation, it would be prudent to conduct an inspection by calling 800-MOLDS (or emailing hello@saniservice.com) for professional advice. They can perform a thorough assessment of your home’s environment, identify potential sources of moisture, and provide recommendations on how to mitigate the risks associated with high humidity.

In addition to professional help, here are some practical steps you can take:

1. Use Dehumidifiers: Continue using dehumidifiers but consider their capacity and if it's sufficient for your space. If not, consider adding more units.
2. Ventilation: Ensure that areas prone to moisture have adequate ventilation. This might include bathrooms, kitchens, and laundry rooms.
3. Air Conditioners: Utilize air conditioning systems which can help in reducing humidity levels indoors. Make sure the AC is properly maintained and serviced regularly.
4. Seal Gaps: Check for gaps around windows and doors that may allow outside moisture to enter your home.
5. Regular Cleaning: Dust, vacuum, and clean regularly to remove any allergens and reduce the growth of mold.

Remember, maintaining indoor air quality during high humidity periods is crucial for the health of all household members, especially those with existing respiratory conditions like asthma or allergies. Regular monitoring and appropriate actions can significantly improve your living environment.
