A sound created by vibrations of the uvula and the soft palate during sleep or the noise produced while breathing through the mouth, caused by air passing through the relaxed tissues in the pharynx.

The majority of people snore to some degree. Snoring is of no clinical importance to the snorer unless it is prolonged and chronic, in which case it seems to be related to an increased risk of developing ischemic heart disease because of a decrease in the amount of oxygen-containing blood going to the heart.

Also, snoring is important if the snorer is so loud as to cause discomfort and lack of sleep for anyone who shares the same sleeping area.
