Snoring can be an annoying problem, especially for your spouse. Although you probably do not think you snore, there is approximately a 45% chance that you do. Snoring can be a sign of a serious medical condition like sleep apnea, or it may just be an annoyance. When you snore, it interrupts the deep sleep you need to recuperate. Snoring starts as your body starts to relax. When the muscles and tissues in the back of you through go slack, they sometimes interfere with air passing through your mouth and nose to your lungs, giving off those rattling sounds.
