Will this help if I have chronic allergies?

Rinsing your nasal passages with saline solution – that is, salt water – helps reduce swollen and congested sinus passages. It also assists with flushing out thickened mucous, irritants like pollen, ragweed and smog, and bacteria and viruses from the nose and sinuses. There have been multiple studies from major universities finding that nasal rinsing can provide significant benefits for people with chronic nasal issues.
