According to a study published in the journal JAMA Pediatrics, a simple nasal spray can greatly decrease children′s snoring, breathing issues, and the need for tonsil removal. The study revealed that saline (salt water) nasal spray was found to be just as effective as an anti-inflammatory steroid nasal spray at treating children′s sleep-disordered breathing after six weeks of treatment.

The Royal Children′s Hospital and Monash Children′s Hospital conducted the randomized-controlled "MIST" study of the sprays with 276 kids who were between the ages of 3 and 12. Approximately 12 percent of children have snoring and breathing disorders when they sleep, which can have serious long-term effects on behavior, cardiovascular health, and cognitive performance.

The researchers from the Murdoch Children′s Research Institute revealed that nasal sprays lowered the number of patients who required tonsil and/or adenoid removal by half, while 40% of the participants reported symptom clearance.

Dr. Alice Baker of Murdoch Children′s stated that Victorian children had to wait for more than a year in the public system for surgery for the removal of tonsils and adenoids. This necessitated the search for an alternate form of care for sleep-disordered breathing. She explained that nasal sprays act to relieve symptoms by clearing the nose and/or lowering inflammation not just in the nose but also in the tonsils and adenoids at the back of the throat.
