Increased nasal breathing decreases snoring and improves oxygen saturation during sleep apnoea.
For many years ENT-specialists have performed surgery to create a good air passage in patients with different kinds of nasal deformities. When having a blocked nose one realizes the importance of being able to breathe through the nose. By moving the nasal wings aside with the fingers, or the medical device Nozovent, most people experience that it is easier to breathe through the nose than ever before, which can also be shown with rhinomanometry. When it is easier to inhale there is less energy in the air passing the palate which means less risk for vibrations creating snoring sounds. In different studies it has been possible to show that snoring can be decreased or prevented when the nasal dilator Nozovent is used. It has also been shown to result in a decrease of the sleep apnoea index and improvement of arterial oxygen saturation during sleep apnoea.
