2. Prevent Mold Growth
The reverse side of that coin is an indoor environment with excessive humidify, which is the ideal breeding ground for both dust mites and mold allergens. If your sensitive to mold take a break from your humidifier and if you do use one, make sure it’s cleaned regularly to prevent bacteria from breeding and infusing the air you breathe.

3. Don’t Smoke Inside
The strong, chemical fumes from second hand smoke will definitely irritate your nasal passages and leave you with dry sinuses and red, dry eyes—even if you are the smoker. Do everyone in your household a favor and smoke outside.

4. Keep the Temperature Cool
If you crank your thermostat in the winter months, you’ll eventually dry out your nasal membranes and cause sinus problems—like nosebleeds and dry congestion. Instead, keep the temperature in your home cooler, and in turn moisture, by keeping it comfortable, but cool. Just throw on an extra layer if you’re chilly.

5. Banish Pet Dander
Allergies to pet dander can live in the air, your carpets, couch cushions, and bedding, just further irritating your sinuses. If you or someone in your house is sensitive to pet dander, give your home a good cleaning in winter—that includes having carpets and ducts cleaned, as well as bathing your dog or cat weekly to cut down on dander.
