Noisy breathing while asleep.
Noisy sounds produced during sleep because of an obstruction to the free flow of air through the passages at the back of the mouth. Snoring affects up to 6o percent of the adult population.
This is usually from vibrations of the soft palate, but the main fault lies in the edge of the posterior pillars of the fauces which vibrate noisily. Mouth-breathing is necessary for snoring, but not all mouth-breathers snore. The principal cause is blockage of the nose, such as occurs during the course of the common cold or chronic nasal catarrh; or in some cases of deviation of the nasal septum or nasal polypi. In children, mouth-breathing with snoring is sometimes due to enlarged adenoids. A further cause of snoring is loss of tone in the soft palate and surrounding tissues due to smoking, overwork, fatigue, obesity, and general poor health. One in eight people are said to snore regularly. The intensity, or loudness, of snoring is in the range of 40-69 decibels. (Pneumatic drills register between 70 and 90 decibels.) Bouts of snoring sometimes alternate with sleep apnoeas.
Loud, audible breathing that occurs through the open mouth due to vibrations of the soft palate while sleeping is referred to as snoring. This phenomenon is frequently triggered by factors that obstruct nasal breathing, such as a cold, allergic rhinitis, or enlarged adenoids. Additionally, snoring is associated with sleep apnea. It tends to be more prevalent among individuals who sleep on their backs. If the root cause of snoring can be addressed, there is a possibility that it will cease.
