The cause of snoring is some kind of blockage in the breathing passage. Those blockages can be of many kinds--here are just a few:
When the airflow in the breathing passage becomes irregular (because of the blockage) then the soft palate starts flapping. This flapping of the soft palate makes the irritating snoring sound.
Snoring cures almost all revolve around clearing the blockage in the breathing passage. This is the reason snorers are advised to lose weight (to stop fat from pressing on the throat), stop smoking (smoking weakens and clogs the throat), and sleeping on one's side (to prevent the tongue from blocking the throat). But for many snorers those pieces of advice are not enough.
Surgery is one option to cure snoring; dental implants are another. There are many devices as nose clips to keep the nose open and jaw mechanics to keep the jaw in the right position. Different aids work for different people.
There is also a less known, but very effective way to stop snoring. It is to exercise the throat, the tongue, and the jaw muscles so the breathing passage will widen and stay open when you sleep.
About sixty percent of men, and thirty percent of women suffer from snoring. This is probably one of the most common dysfunctions known.
Most of the time snoring is considered not dangerous, but if serious it can become a life threatening sickness called sleep apnea .
Even if snoring is not very bad, it can cause the snorer's spouse to lose sleep. Being sleepy all day long can also be life threatening for the person and those around them.
Snoring is usually an involuntary act during sleep, but may also be produced voluntarily.
