Snoring is a breathing noise that occurs during sleep and can be very disruptive to you or your bed partner.
While breathing in, the air passage between the upper soft palate and the throat or base of the tongue opens and closes. As muscles relax, there is a partial obstruction to the air passage as noted in the red area, causing the tissues to vibrate and make the snoring noise.
This abnormal breathing that causes sleep disruptions affects approximately 90 million American adults; 37 million on a regular basis.
Persons most at risk are males and those who are overweight. It often increases with age.
Loud snoring is particularly serious as it can be a symptom of sleep apnea and can be associated with high blood pressure and other health problems.
