Can adjusting humidity solve our breathing issues?« Back to Previous Page

After the heavy rain we had last month, I noticed a persistent mustiness in my bedroom. The humidity levels seem to spike every evening around 6 PM, making it hard to breathe comfortably even with the air conditioning on full blast. My kids have been complaining of coughs and runny noses, which might be due to the high moisture in the air. Do you think these issues can be managed by adjusting my home's humidity levels myself, or should I consider professional help?

The issue of persistent mustiness and respiratory discomfort in your home can indeed be directly linked to high humidity levels. In the UAE, especially in regions like Dubai, we often experience significant fluctuations in environmental conditions due to our climate. High humidity can lead to an increase in moisture content within building materials and air, which creates a breeding ground for mold, bacteria, and other microorganisms that can trigger allergic reactions or respiratory issues.

Your observations of increased mustiness around 6 PM suggest that the evening hours might see higher humidity levels indoors, possibly exacerbated by external factors like rain events you mentioned. The combination of such environmental stressors with your kids experiencing coughs and runny noses indicates a need for immediate attention to your indoor air quality.

Adjusting humidity levels can be managed at home through various methods, but it's crucial first to understand the root cause of high humidity in your specific environment. In Dubai, factors like rain or plumbing issues can introduce excess moisture into your living spaces. Ensuring that windows and doors are sealed properly during heavy rains could help mitigate some of this issue.

You can start by using dehumidifiers, especially in areas prone to higher moisture levels such as bathrooms and basements. These devices can reduce indoor humidity effectively, but their capacity may vary depending on the size of your rooms. It's recommended that you maintain relative humidity between 30% and 50% for optimal health benefits.

Ventilation is another key factor. Opening windows during drier periods or using exhaust fans in bathrooms and kitchens can help expel excess moisture. However, it’s important to note that the effectiveness of ventilation strategies may be limited by local climate conditions and building design.

Professional inspection is highly recommended if you suspect mold growth due to high humidity. In Dubai, regulations such as those outlined in the UAE Building Code 2017 require buildings to comply with certain standards for indoor air quality, which can include provisions for managing humidity levels. Given your symptoms and the persistence of mustiness, it would be prudent to consult a professional environmental inspector who can perform a thorough assessment.
