Question

about snoring
what causes snoring?
snoring occurs when air moving through the mouth causes the soft palate (the tissue in the roof of the mouth near the throat) to vibrate. this happens without vibration in normal conditions. but sometimes fatty tissue or swollen tonsils or adenoids make the air - pathways become narrow. the passing air then meets turbulence. this produces the vibration or snoring.
no one knows of a single cause of snoring. but several things seem to make it worse or more common. these include increases in weight, the use of alcohol or other sedatives before bedtime, chronic nasal congestion and enlarged tonsils or adenoids. a serious condition called sleep apnea can also cause snoring. this makes a person wake up because it interrupts ones breathing. sleep apnea requires a different treatment than does snoring.
how can you stop it?
because we dont know of a single cause of snoring, we dont have a good cure for it. some things may help, though. if weight or alcohol or sedative use is contributing to the snoring, the snorer can lose weight or cut out the alcohol or sedative. sleeping on ones side instead of the back may help, too. a device can be placed in the mouth that makes the jaw come farther forward. laser and other types of surgery can remove the uvula, the piece of tissue that hangs down in the back of the mouth. also, a procedure using high - frequency radio waves will shrink surrounding tissue. makers of sprays claim their product will lubricate the uvula and stop the blockage that causes snoring. but there is no scientific proof that such treatments are effective.
in fact, all of these devices or procedures have unpredictable results. often they only help the snorer for a short time. snoring
