From MedPage Today:
"Contrary to popular belief, irrigating the nose every day with the help of a Neti pot may actually make patients more susceptible to sinus infections. Those who stopped using the nasal saline wash on a regular basis had a 62% decrease in the frequency of acute rhinosinusitis, Talal M. Nsouli, MD and colleagues reported at the 2009 American College of Allergy, Asthma, & Immunology meeting.
"I don't have anything against short-term nasal saline irrigation -- even aggressive nasal saline irrigation for three, four days or one week is totally fine," Nsouli said. "But when we are doing it on a daily basis, we are modifying the immunological biochemistry of the nose."
