Woman flushing her nose with a neti pot
Nasal irrigation, (also called nasal lavage or nasal douche) is a personal hygiene practice in which the nasal cavity is washed to flush out mucus and debris from the nose and sinuses. The practice is reported to be beneficial with only minor side effects. Nasal irrigation can also refer to the use of saline nasal spray or nebulizers to moisten the mucous membranes.
Nasal irrigation can be an effective therapy to relieve symptoms of both chronic sinusitis as well as acute sinuitis caused by upper respiratory tract infections such as the common cold. The evidence for use in chronic sinusitis is weak.
Adverse effects include nasal irritation, nosebleeds, headache, and drainage after the irrigation is done. It is generally well-tolerated.
There is a risk of infection if the water is not sterile or the device is not cleaned after use. If the device is used improperly this can be harmful.
Mechanism of action
Solutions and devices
The water should not be tap water, which may contain small amounts of bacteria that are safe to drink but may be dangerous in the nose. The water should be sterile or filtered for micro-organisms; if tap water is used it should be boiled. Saline solution is also sometimes used.
Neti pots are commonly used and rely on gravity and head position in order to rinse the outer sinus cavities. Typically they have a spout attached near the bottom, sometimes with a handle on the opposite side.
Various squeeze bottles for nasal irrigation have also been used to apply the water.
Bulb syringes are commonly used for infants and children.
There are also irrigation machines available that utilize electric motor-driven pumps.

The earliest record of nasal irrigation is found in the ancient Hindu practice of Indian Ayurveda whose roots are traced to the Vedas. It was customary to perform jala-neti daily, as part of soucha (personal hygiene according to scriptures). Jala-neti, which means to cleanse the nose with water, is an old yogic technique from India. The container used to administer the saline is called a "neti pot". This process removes mucus, dirt, and clears the nose. A second neti technique known as sutra neti uses a piece of string instead of water.
