Could recycled air from AC cause sore throat?« Back to Previous Page

After the intense heatwave we just had last week, my throat has been feeling sore and scratchy every morning. The air conditioning in our apartment runs almost all day to keep up with the temperature outside, but I’m worried about how much time we’re spending breathing that recycled air. Could this be causing my symptoms? How urgent is it for me to see a doctor or are there steps I can take at home to alleviate them?

Yes, it is plausible that the recycled air from your air conditioning system could be contributing to your sore throat. In Dubai and other regions of the UAE, the air conditioning systems are often run for extended periods during heatwaves or cooler weather. This can lead to a few potential issues: reduced air quality, dryness in the air, and possible microbial growth due to stagnant conditions.

Firstly, consider that the indoor environment's air quality is significantly affected by the HVAC system. If your apartment has a poorly maintained AC unit, it could be circulating dust, pollen, or even mold spores, all of which can irritate the throat lining and cause discomfort. In Dubai, due to the high temperatures and humidity, there's also an increased risk of mold growth in damp areas like bathroom and kitchen.

Secondly, the air conditioning units typically use a recirculation mode that reuses the same air within the space, thereby reducing fresh air intake. This can lead to a dry environment, which might exacerbate throat irritation especially if it's already inflamed or irritated from dust or allergens in the air.

In terms of addressing this issue, you should first inspect your AC unit for any signs of damage, mold growth, or accumulated dirt. Regular cleaning and maintenance by a certified technician are essential to ensure that the system is functioning optimally and not contributing to indoor air quality problems.

To alleviate symptoms at home, try these steps:
• Increase humidity levels in your apartment using a humidifier. This can help prevent dryness in the throat.
• Use an air purifier with HEPA filters if you suspect dust or allergens are causing irritation.
• Regularly clean your AC filter and consider changing it every few months depending on usage, especially during high heat periods.
• Ensure proper ventilation when possible to introduce fresh outdoor air into the space.

It's important to note that if symptoms persist despite these measures, a professional indoor environmental inspection might be necessary. You could contact Saniservice at 800-MOLDS (800-66537) or email hello@saniservice.com for assistance. Remember, maintaining good indoor air quality is crucial in Dubai's climate, and proactive steps can prevent more serious health issues.

Lastly, while the above measures are practical steps you can take at home, if your symptoms worsen or do not improve within a few days, it would be wise to consult with a healthcare professional for further evaluation.
