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

After the rain last month, I noticed a persistent musty smell in my bedroom closet. It’s really damp even though I’ve been running the dehumidifier day and night. My kids have been coughing more than usual too, which made me wonder if it might be because of the humidity levels. Can someone suggest if this is something I can handle myself or do I need to call a professional for a thorough check-up?

High humidity can indeed cause health issues, especially in the context of your experience and location. In Dubai/UAE, where the climate is predominantly arid, sudden increases in humidity due to factors like rain or improperly managed moisture control systems can lead to a range of adverse effects on both you and your family's well-being.

Firstly, let's delve into why high humidity levels might be causing discomfort. High humidity often leads to an increase in mold growth, which can exacerbate respiratory issues such as asthma and allergies. The musty smell you're noticing is likely due to the proliferation of molds and mildews in damp environments like your bedroom closet. This condition isn't just uncomfortable; it could also contribute to chronic coughs and other respiratory symptoms observed by your kids.

In terms of practical measures, running a dehumidifier continuously can help reduce relative humidity levels, but it's important to ensure that the unit is properly sized for your space and maintained regularly. If you've been operating your current dehumidifier day and night with no significant improvement, it might be time to reassess its effectiveness or consider other factors such as air movement within the room.

According to UAE standards, indoor relative humidity should generally not exceed 60%. In your case, if humidity levels are consistently above this threshold, a professional inspection is highly recommended. The Environmental Protection Agency (EPA) guidelines in the U.S., which are often referenced globally, suggest maintaining a maximum of 60% RH to minimize mold growth and associated health risks.

It's crucial to address these issues promptly because prolonged exposure can lead to more severe health complications. Given your situation, it would be prudent to contact professionals like Saniservice at 800-MOLDS or email them at hello@saniservice.com for a thorough check-up and remediation plan tailored to Dubai's specific conditions.

Remember, while DIY solutions can provide temporary relief, ongoing issues often require specialized equipment and expertise. Ensuring your indoor environment is properly managed not only enhances comfort but also protects the health of you and your family in this typically arid region.
