Snoring is the noise of the soft palate and the loose tissue in the mouth, nose and throat, like the uvula, adenoids and/or tonsils, vibrating during sleep. It generally occurs when you sleep on your back and during the inhaling process. As the throat muscles lose their firmness due to age, and relax during sleep, the loose hanging soft tissues cause the air passages to narrow. The obstructing elements in the throat touch one another, causing friction and subsequent vibration. The faster the force of air and the narrower the air passage, the louder and more resonant the snore becomes.
