First seen Jan 06, 2026 · Last updated Jun 13, 2026 · Updated 29 times
Summary
This study tests a hypertonic (extra salty) seawater spray used in a nebulizer to see if it helps relieve nasal symptoms, improve sleep, and thin mucus in people with colds, sinus infections, or similar upper respiratory infections. About 110 adults and children aged 2 and older will use the spray at home for 7 days and report their symptoms. The goal is to see if the spray is safe and effective for easing discomfort, not to cure the infection.
