Could AC causing kids' cold symptoms?« Back to Previous Page

The AC unit in our living room has been running non-stop since last week, even when it’s not that hot outside. My kids have been complaining of a stuffy nose and coughing more than usual lately. We’ve lived here for two years, and this is the first time we’ve noticed such issues. Could the constant air conditioning be causing their cold symptoms?

Indeed, the symptoms your kids have been experiencing could be linked to prolonged exposure to air conditioning. In Dubai and UAE conditions, air conditioning systems often run non-stop during hot months, but continuous operation can introduce several issues that might affect indoor air quality and subsequently impact respiratory health.

Firstly, it’s important to understand how AC units function in our region. Air conditioners remove moisture from the air as part of their cooling process. This is crucial for comfort but can also lead to a dry environment if overused. Dry air may irritate mucous membranes, potentially leading to stuffy noses and coughing.

Moreover, the constant operation of an AC unit without proper maintenance can introduce contaminants into your living space. Dust, mold spores, and even microorganisms that thrive in humidifiers attached to AC systems could be circulating due to inadequate cleaning or filter replacement. Additionally, improper ductwork sealing might allow outdoor pollutants such as pollen or dust mites inside.

Given the symptoms you've observed, it would be prudent to schedule a professional inspection of your air conditioning system. A certified HVAC technician can ensure that the unit is functioning optimally and check for any potential issues with filters, dehumidifiers, or the overall system. Regular maintenance, including cleaning and replacing filters as per manufacturer recommendations, is crucial.

In Dubai, you might want to consider consulting a professional who specializes in indoor environmental quality (IEQ). They can conduct thorough testing for contaminants such as mold, bacteria, and allergens, which could be exacerbating your children's symptoms. The UAE has specific regulations regarding air quality standards in residential buildings, so it’s important to ensure compliance.

If you decide to proceed with an inspection or maintenance, consider calling 800-MOLDS (800-66537) for mold testing and remediation services or email hello@saniservice.com for a comprehensive assessment of your indoor environment. Additionally, the Dubai Municipality provides guidelines on maintaining healthy living spaces, which can be a good resource.

To address the issue in the meantime, try to increase humidity levels slightly by using a humidifier (if appropriate) and ensure that you are changing or cleaning your AC filters regularly. Also, maintain good ventilation when possible, but avoid letting cold air from the AC directly hit your kids as this could contribute to their discomfort.

Remember, while air conditioning is essential in our hot climate, it’s equally important to balance its use for both comfort and health.
