What Causes Snoring?
Snoring occurs when the flow of air through the mouth and nose is physically obstructed. Air flow can be obstructed by a combination of factors, including
Obstructed nasal airways: Some people snore only during allergy seasons or when they have a sinus infection. Deformities of the nose such as a deviated septum (a structural change in the wall that separates one nostril from the other) or nasal polyps can also cause obstruction.
Poor muscle tone in the throat and tongue: Throat and tongue muscles can be too relaxed, which allows them to collapse and fall back into the airway. This can result from deep sleep, alcohol consumption, or use of some sleeping pills. Normal aging causes further relaxation of these muscles.
Bulky throat tissue: Being overweight can cause bulky throat tissue. Also, children with large tonsils and adenoids often snore.
Long soft palate and/or uvula: A long soft palate or a long uvula (the dangling tissue in back of the mouth) can narrow the opening from the nose to the throat. When these structures vibrate and bump against one another the airway becomes obstructed, causing snoring.
Health Risks Associated With Snoring
Habitual snoring can be a sign of a serious health problem, including obstructive sleep apnea. Sleep apnea creates several problems, including:
Interruptions of breathing (lasting from a few seconds to minutes) during sleep caused by partial or total obstruction or blockage of the airway
Frequent waking from sleep, even though you may not realize it
Light sleeping. Waking up so many times a night interferes with the normal pattern of sleep, causing more time to be spent in light sleep than in more restorative, deeper sleep.
Strain on the heart. Prolonged suffering from obstructive sleep apnea often results in higher blood pressure and may cause enlargement of the heart, with higher risks of heart attack and stroke.
Poor night's sleep. This leads to drowsiness during the day and can interfere with your quality of life and increase risk for car accidents.
