Winter is a season full of wonderful opportunities to enjoy family traditions, holiday activities and time with loved ones. It’s also the season when sinus infections tend to linger bringing stuffy noses and pressure behind the eyes. As temperatures drop and indoor heaters kick on, many Minnesotans may find themselves fighting recurring sinus infections all season long.
Let’s examine why winter may cause frequent sinus infections, and what you can do to relieve symptoms, stay heathy, and get back to enjoying your holidays.
Three Causes of Winter Sinus Infections

There are three central causes for winter sinus infections:
- Cold and flu season. Winter is the peak time for viruses. A simple cold can quickly turn into a sinus infection if inflammation traps mucus inside the sinuses. Because people spend more time indoors, colds and flu can spread easily from person to person.
- Indoor allergen exposure. Dust mites, mold spores and pet dander tend to build up indoors. If you’re sensitive to these allergens, you may notice ongoing inflammation that can contribute to more frequent sinus infections.
- Dry indoor air. Heating systems keep you nice and cozy in the chilly Minnesota weather, but they also contribute to drier indoor air. That dryness causes your sinus tissues to crack and swell, creating an ideal environment for congestion and infection.
If you have other risk factors such as nasal polyps, a deviated septum or a weakened immune system, it’s crucial to address these underlying issues, as they can increase your susceptibility to frequent sinus infections during the winter.
Ways To Soothe Your Sinuses This Season
An estimated 29 million U.S. adults are diagnosed with a sinus infection each year. While you may not be able to prevent every sinus infection, understanding what causes your inflammation and taking steps to calm it can significantly lower your risk of recurring infections. Try the following:
- Wash your hands regularly to reduce the spread of germs
- Clean your home weekly to reduce dust, mold and pet dander buildup
- Run a humidifier to keep the moisture level in your home between 30% and 60%
- Drink plenty of water or herbal tea daily
- Use a Neti Pot or nasal irrigation system to flush your sinuses with saline solution
