Snoring is caused by vibrations from the soft palate and other tissue in the mouth, nose and throat. The vibrations are caused by turbulence in the respiratory passages when we breathe. The turbulence is caused by a partial blocking of the respiratory passages, which can be anywhere between the tip of the nose to the vocal chords. Snoring is often a symptom of other conditions, including allergic reactions. With an allergic reaction, the nasal mucous membranes become inflamed and swell, partially blocking the respiratory passages and preventing correct breathing through the nasal respiratory passages. This blockage of the nasal respiratory passages can lead to snoring and impaired sleep. The products from Nasaline ease breathing through the nose, helping to reduce snoring.
