Prevention
There are no methods that have been scientifically tested and proven to prevent acute or chronic sinusitis. However, your healthcare provider may recommend a variety of measures that may provide you with some benefit.
-
Keep your nose as moist as possible with frequent use of saline (salt) sprays.
-
Avoid very dry indoor environments and use a humidifier, if necessary. But be aware that if you have allergies to molds, house dust mites, or cockroaches, a humid environment may also create problems.
-
Avoid exposure to irritants, such as cigarette and cigar smoke or strong odors from chemicals.
-
Avoid exposure to anything you're allergic to. If you have not been tested for allergies and you are getting frequent sinus infections, ask your healthcare provider to give you an allergy evaluation or to refer you to an allergy specialist.
-
Avoid long periods of swimming in pools treated with chlorine, which irritates the lining of the nose and sinuses.
-
Avoid water diving, which forces water into the sinuses from the nasal passages.
You may find that air travel poses a problem if you are suffering from acute or chronic sinusitis. As air pressure in a plane is reduced, pressure can build up in your head, blocking your sinuses or the eustachian tubes in your ears. As a result, you might feel discomfort in your sinuses or middle ear during the plane’s ascent or descent. Some health experts recommend using decongestant nose drops or sprays before a flight to avoid this problem.
