Dry indoor air may be the common culprit to blame for your fall sore throat
Dry air and heating
Fall air can leave the throat feeling sore, even when a cold or flu is not the cause. Experts point to dry conditions as a likely explanation. NBC 4 New York meteorologist Matt Brickman said the pattern was expected to last through the weekend. He also warned that running the heat can worsen the dryness indoors.
Why dryness matters
Heating reduces moisture inside, potentially leaving indoor air very dry. Cleveland Clinic family medicine specialist Dr. Josue Limage said dried mucus is less able to catch germs effectively. Dry indoor air may also leave eyes itchy or crusty in the morning, according to the report.
Ways to ease irritation
Using a humidifier and drinking enough fluids may help protect the nose and throat when heating is needed. This may be particularly useful near bedtime, when saliva production that moistens the throat decreases.
Humidifiers can encourage mold or bacterial growth if they are not cleaned properly. Dr. William Li said gargling warm salt water can loosen mucus and draw excess fluid from inflamed tissue; the Mayo Clinic advises doing so several times daily.
Key points
- Dry fall air, rather than a cold or flu, may be behind a sore throat.
- Indoor heating can further reduce moisture and dry mucus.
- A humidifier and staying hydrated may help, especially around bedtime.
- Clean humidifiers regularly, and consider gargling warm salt water for irritation.
