Nasal irrigation
personal hygiene practice for rinsing out nasal passages.
Nasal irrigation (also called nasal lavage, nasal toilet, neti pot 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, in order to enhance nasal breathing. Nasal irrigation can also refer to the use of saline nasal spray or nebulizers to moisten the mucous membranes.
Medical uses
Nasal irrigation can be an effective therapy to relieve symptoms of acute sinusitis caused by upper respiratory tract infections such as the common cold. The evidence for effectiveness in relieving chronic sinusitis is weak.
It can also be useful for the temporary relief of the symptoms associated with allergic rhinitis.
Adverse effects
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. In fact, proper application suggests the use of pre-boiled water or saline water.
