Ask a Doctor: Bad air quality can cause mild symptoms even in healthy people

Q: I’ve noticed the air in Chattanooga has been really smoky lately. I heard it’s from controlled burns, but I’m feeling more congestion and irritation than usual. Is this something to be worried about?

A: You’re absolutely right. Chattanooga’s air quality has been less than ideal lately. With controlled burns happening in the region and dry conditions making things worse, we’re seeing an increase in fine particulate matter (PM2.5) in the air. These tiny particles can travel deep into your lungs and even enter your bloodstream, causing irritation and potential health issues.

For most healthy people, short-term exposure might just cause mild symptoms like coughing, a scratchy throat, watery eyes or even a sore throat. The smoke and dry air can irritate the lining of your throat, making it feel raw or uncomfortable. Staying hydrated, using throat lozenges and running a humidifier indoors can help relieve discomfort.

For those with asthma, COPD, heart conditions or even seasonal allergies, this poor air quality can trigger more serious reactions – wheezing, shortness of breath or even an increased risk of heart problems. If the air quality is bad, it’s best to check local air reports before heading outside and limit outdoor activity, especially if you have any respiratory conditions. Staying indoors with windows and doors closed can help, and using an air purifier, if available, can reduce exposure to airborne particles. If you have to be outside, wearing an N95 mask can help filter out harmful pollutants.

Listening to your body is key. If you notice increased shortness of breath, chest discomfort or worsening asthma symptoms, don’t ignore it. Take it easy, use prescribed inhalers if needed and seek medical attention if symptoms become severe. Drinking plenty of water and getting good rest can also help your body recover from the extra strain of breathing in pollutants. Unfortunately, we can’t control the burns or the weather, but we can be proactive about protecting our lungs. Stay safe, Chattanooga, and breathe as easy as you can!
