This product is a lip piece for nasal breathing during sleep. Traditionally, mouthpieces are worn between the upper and lower teeth inside the mouth, but this lip piece is placed between the upper and lower gums and lips, covering the entire lip, and has a slightly elongated ring shape. It utilizes the principle that even ordinary people can achieve nasal and diaphragmatic breathing by opening their mouths wide like singers. One piece can be fitted to set two sizes, slightly elongated vertically and slightly horizontally. This allows for adjustments to the size of the person's mouth and jaw closure, adjustment of the amount of air, and multi-purpose use such as daytime fitting practice or nighttime sleep use. The material is synthetic resin, and you can choose between a harder (plastic) and a softer (elastomer) version. When this product is worn on the lips, the larynx opens, ensuring an open airway during sleep, allowing for smooth nasal breathing, and preventing snoring and sleep apnea. Furthermore, since it prevents mouth breathing even when the mouth is open, it can prevent various problems associated with mouth breathing. It can be used by a wide range of ages, from infants with underdeveloped lower jaws who grind their teeth, to adults with teeth clenching, dry mouth, temporomandibular joint disorders, and elderly people at risk of aspiration, and is harmless. Once the discomfort of wearing it is overcome, it promotes restful sleep with light and safe nasal breathing. Other benefits include improved blood flow to the muscles around the mouth, while at the same time creating a slight tension in the lips, which is good for blood flow to the brain. The lips relax and the salivary glands work, so saliva is produced, but the structure prevents saliva from spilling out of the mouth. The base of the tongue is more easily moved forward, so the epiglottis (the lid for swallowing) moves. It is also expected to help prevent silent aspiration pneumonia.
