Studies do show that occasional sinus rinsing is beneficial, especially when a person is experiencing a severe bout of allergies or the flu. Regarding the use of a neti pot with saline solution, Dr. Paul Little, the lead author of a study published in the Canadian Medical Association Journal, states, “In addition to improving sinus symptoms, headaches were reduced, there was less use of over-the-counter remedies, and people also said they were less likely to contact the doctor again for a future attack of sinusitis.”
Researcher Dr. Talal M. Nsouli and his colleagues found that, “62 percent of people had a significant drop-off in the frequency of their rhinosinusitis infections after discontinuing saline irrigation. Those patients also had 50 percent fewer sinus infections than those who remained on the nasal saline irrigation therapy.” Nsouli explains that continuous nasal rinsing depletes the nasal mucus to a dangerous degree, which rids the body of key antibodies immunoglobulin A, immunoglobulin G, lactoferrin, and lysozyme.
Cleaning the sinuses has strong benefits but overdoing it can have harmful consequences. The best way to make sure your nose is clean without unwanted side effects is to use a saline nasal spray with xylitol. Xylitol is a natural ingredient that breaks up bacterial biofilm so bacteria can’t stick to nasal tissues, to more effectively wash the nose of irritants like dust, dander, and pollen.
