Nasal irrigation is a personal hygiene practice in which the nasal cavity is washed to flush out excess mucus and debris from the nose and sinuses. This helps the body get rid of any irritating and infectious agents.
Irrigation can provide immediate relief for sinusitis by unblocking the nasal passages, clearing the blockages that cause the discomfort and removing much of the mucus and bacteria.
There are several different types of products that can be used for nasal irrigation. These include a bulb syringe, squeeze bottle, or neti pot. With these devices, the user manually pours or sprays a mixture of salt and water into the nostril. The fluid flows through the nasal cavity and into the other nostril. There are also more high-tech nasal irrigation systems available which propel the solution into the nose, allowing the user to control the spray and pressure.
Nasal irrigation helps to reduce the inflammation of the sinuses and enables the immune system to work more efficiently by reducing the amount of mucus and bacteria that has built up, allowing the body to recover more quickly.
However, this form of treatment is a quick fix solution which is best used in moderation. This is because the treatment also removes the beneficial bacterial that is present in your nose1.
