Seasonal allergies are one of the obvious causes of nasal congestion. But other types of environmental allergies can also cause snorting year-round, says Sarah, an assistant professor at New York University’s Grossman School of Medicine. “Pet hair, dander, saliva, and urine can swell and inflame the soft tissues of your nose, causing stuffiness, as do ticks,” says Dr. Hochman. Ordinary irritants, such as perfume, car exhaust, and cigarette smoke, can also cause your nose to react, Dr. Dykewicz added.
Viral infections such as the common cold, flu, and Covid-19 can also cause congestion, as can viral pneumonia. Other factors include changes in temperature and humidity, Dr. Dykewicz said, but some people have chronic inflammation of unknown origin.
A stuffy nose that lasts longer than two weeks, especially after a cold, could be a sinus infection, says Dr. Hochman. Inflammation of sinus tissueOther telltale signs of a sinus infection include ear pain, fever, and sore cheeks when touched. Sinus congestion and pain in the face or forehead when bending over (for example, when tying shoes) may be another sign of a sinus infection and should be seen by a doctor There is a need, says Dr. Hochman.
Congestion can also be a surprising by-product of some drugs, including Viagra and some blood pressure-lowering drugs, ACE inhibitors, Dr. Dykewicz said. If so, it is important to research potential side effects of any medications or supplements you may be taking and consult with your prescribing physician.
How to clear congestion
It may sound simple, but first try to get your nose as clean as possible by gently blowing on a tissue, says Raj Sindwani, M.D., an otolaryngologist at the Cleveland Clinic. Dykewicz says he can cleanse his nasal passages two to three times a day using an over-the-counter saline nasal spray. Staying hydrated is also important because liquids help thin the mucus in your nose, allowing it to drain more easily.
