By Mayo Clinic staffTo reduce the risk of sinusitis, keep your sinuses healthy.
- Wash your hands often. Soap and water can help you avoid the upper respiratory infections that can lead to sinusitis. You may want to ask your doctor about a yearly flu vaccine as well.
- Avoid irritants. Avoid cigarette, cigar and pipe smoke. These and other air pollutants can cause your sinus membranes to swell.
- Use a humidifier. Adding moisture to dry indoor air can help prevent sinusitis — but don't overdo it. High indoor humidity can promote mold and dust mite growth in your home. Be sure the humidifier is clean and kept free of mold.
