Nasal polyps take up space in your nose, so it’s important to avoid irritating substances that can cause inflammation of the nasal membranes, which could block off even more of your airway. Avoid exposure to dust, smoke, paint fumes, household chemicals, and perfumes or cologne. If you have allergies, it’s essential to steer clear of your known allergens.
If you’re allergic to pollen, for instance, stay inside as much as possible when local trees are pollinating. Ask someone in your household (or simply a close friend) to dust and vacuum; or, wear a dust-filtering mask over your nose and mouth.
