Can high humidity cause health issues?« Back to Previous Page

After the recent heavy rains last month, I noticed a persistent musty smell in my bedroom closet. The humidity has been really high, even with the dehumidifier running constantly. My kids have been coughing more than usual, which leads me to suspect it might be related to the dampness. Do you think there's something else I can do on my own to improve the situation before considering professional help?

High humidity can indeed cause a myriad of health issues, especially in the warm and humid climate of Dubai/UAE. The persistent musty smell you're experiencing alongside your kids' increased coughing could very well be linked to high indoor humidity levels.

Firstly, it is important to understand that excessive moisture in the air can lead to the growth of mold and mildew, which are major culprits behind respiratory issues. In Dubai's climate, where even brief periods of rain can increase indoor humidity significantly, maintaining a controlled environment becomes crucial. The UAE does not have specific regulations on acceptable indoor humidity levels, but as a general guideline, it is recommended to keep the relative humidity within the range of 30% to 50%. Higher humidity promotes mold growth and makes dust mites thrive, both of which can exacerbate allergies and asthma.

In your situation, running a dehumidifier continuously may not be enough. Ensure that you are also addressing other sources of moisture in your home. Check for leaks around windows, doors, and plumbing lines. Even minor issues like condensation on cold surfaces can contribute to high humidity levels.

To improve the indoor air quality before seeking professional help, consider using a hygrometer to monitor the humidity level. This will give you an accurate reading and help determine if your current efforts are sufficient or if more drastic measures are needed. Additionally, ensure good ventilation by opening windows when possible, especially during cooler times of day.

Practically speaking, regular cleaning with anti-microbial agents can help reduce mold spores. However, if the musty smell persists despite these efforts, it may be a sign that larger issues need addressing. Mold growth in hidden areas like behind walls or under carpets could be causing this unpleasant odor and posing health risks to your family.

Remember, while you might manage some symptoms on your own, persistent respiratory problems should not be ignored. If the situation does not improve with basic home remedies, it is advisable to contact a professional environmental inspection company for a thorough assessment. Here in Dubai, companies like Saniservice offer reliable services and can provide expert advice tailored to local conditions.

In summary, high humidity can indeed impact your health significantly, particularly by fostering mold growth which triggers allergies and worsens respiratory issues. Keep monitoring the humidity levels and take proactive measures to control moisture. Should you need further assistance, don't hesitate to reach out for professional help.
