Despite your best efforts you may not be able to prevent the occurrence of sinusitis. However, there are some things you can do that may help lower your risk of developing the condition. These include:

• 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. Note: if you have allergies, humidity may exacerbate your symptoms.
• Avoid exposure to irritants, such as cigarette and cigar smoke or strong odors from chemicals.
• If you have allergies, try your best to avoid exposure to allergens that trigger your symptoms, Work with your doctor to help manage your symptoms.
• If you have asthma, take care to prevent asthma attacks by eliminating potential triggers of an asthma attack.
• Avoid or limit situations in which you are exposed to non-atmospheric air pressure, such as water diving or airplane travel. Some health experts recommend using decongestant nose drops or sprays before a plane flight, but talk with your doctor first to make sure this is appropriate for you.
• Reduce your risk of upper respiratory infections by practicing good hygiene. If you do have a cold, treat your symptoms right away by drinking plenty of fluids and keeping your nasal passages clear by using decongestants.
• Avoid cigarette smoke and polluted air. Exposure to tobacco smoke is a risk factor for sinusitis and other air contaminants can also irritate the nasal passages.
• Limit alcohol use. Consumption of alcohol can cause sinus passages to swell.
