We spend a significant portion of our lives sleeping, and the quality of our sleep influences our daytime activity. Sleep is supposed to be a time of calm and rest, but it can sometimes be extremely noisy and restless. Rest is sometimes accompanied by noise of varying intensity: snoring ! Besides disrupting a partner's sleep and causing relationship problems, snoring can signal the beginnings of a more serious disorder such as sleep apnea , or, when significant, obstructive sleep apnea syndrome.

This is then 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 approximately 10 million French people.

Obstructive sleep apnea syndrome (OSAS) is the occurrence of respiratory pauses (apneas) or a decrease in nocturnal respiratory airflow (hypopnea) resulting in a decrease in blood oxygen (desaturations) repeatedly (5 episodes per hour).

There is a continuum of development between a simple snorer and a snorer with sleep-disordered breathing; this development is insidious and gradual. It is estimated that 10 to 20% of patients are likely to develop sleep disorders with age.
