What is the advantage of nasal irrigation?

Some amount of mucus production from the nasal and sinus lining is normal. Allergies and infections will cause excessive mucus production. This creates nasal and sinus symptoms such as a runny and stuffy nose or post nasal drip. When you rinse your sinuses, you wash away excess mucus, allergy causing particles and irritants such as pollens, dust particles, pollutants and bacteria, thus reducing the inflammation of the mucus membrane. Normal mucosa will fight infections and allergies better and symptoms will be reduced or possibly eliminated.
