We spend a good part of our lives asleep, and the quality of our sleep influences our daytime activity. Sleep is supposed to be a time of calm and recuperation, but it can sometimes be extremely noisy and agitated. Rest is sometimes accompanied by noise pollution of varying intensity: snoring! In addition to disrupting your partner's sleep and causing relationship problems, snoring can be the first sign of a more serious disorder, such as sleep apnea, or, when it is severe, of obstructive sleep apnea syndrome.
This is a real disease, and there is an evolutionary continuity between simple snoring and the development of apneas.
Definition of snoring and sleep apnea
Snoring is the emission of a nocturnal noise by vibration of the upper airways, and affects around 10 million French people.
Obstructive Sleep Apnea Syndrome (OSAS) is the occurrence of respiratory arrest (apnea) or decreased nocturnal respiratory airflow (hypopnea), resulting in repeated (5 episodes per hour) blood oxygen depletion (desaturation).
There is a continuity of evolution between a simple snorer and a snorer with sleep-disordered breathing, which sets in insidiously and progressively. An estimated 10-20% of patients are likely to develop sleep disorders as they age.
