What are the benefits of nasal irrigation, and what is the recommended frequency?

Nasal irrigation is a very safe practice with no significant side effects aside from possible nasal irritation at first use.

Some may experience tinnitus, which should resolve on its own, or a stinging sensation in the nasal cavity, which is preventable by using saline with the right concentration (0.9% sodium chloride solution) and the proper techniques.

Nasal irrigation can be done 1-2 times daily. For those suffering from upper respiratory infections, doctors recommend nasal irrigation twice per day, morning and evening, to alleviate symptoms.
