" Why does it happen?   Snoring occurs when the flow of air through your mouth and nose is obstructed. This, in turn, causes tissues such as the uvula and soft palate (the soft part of the roof of your mouth) to vibrate as you breathe in and out, creating noise.   Who does it affect?   Snoring becomes more common with age, especially among men. You&amp;#039;re also more likely to snore if you&amp;#039;re overweight or pregnant. Other contributing factors include   -Nasal congestion due to a cold or allergies -Poor muscle tone in the tongue and throat -Deformities of the nose or nasal cavity, such as a deviated septum.   When should you worry?   If you choke or gasp during sleep, have morning headaches or are very sleepy during the day, you may have obstructive sleep apnea, a condition in which brief pauses during nighttime breathing lead to a drop in your blood-oxygen level, causing the heart to pump harder. Sleep apnea can be ruled out by a sleep study, in which breathing and heart rate are recorded through small sensors placed on areas like your forehead, scalp and finger. You may be required to stay overnight at a sleep lab. If you (or your partner) are a loud, habitual snorer or often wake up feeling unrested, see your doctor for a sleep apnea evaluation. Untreated sleep apnea can increase the risk of high blood pressure, diabetes, heart attack or stroke. "^^<http://www.w3.org/2001/XMLSchema#string>
