Chest | Otorhinolaryngology | Stop Snoring (Symptom)
Snoring occurs when the column of the air that enters through the mouth or nose into the lungs, is causing the vibration of the airway tissue. Usually this happens as a result of a narrowing or airway obstruction in the nose, mouth (oral cavity) or neck. During sleep, the inspiration air enters through the mouth or nose and passes through the soft palate (the back of the upper wall of the mouth) to get then into the lungs. The back of the mouth where the tongue and the upper throat meet the soft palate and uvula (extension musculoskeletal suspended lining the posterior border of the soft palate in the mouth floor) is collapsed. If this area collapses enough, the airway narrows or blocks.
Obstruction of the airway narrowing or disrupt the airflow path, which makes the soft palate and uvula to vibrate, thus hitting the back of the throat causes snoring. Tonsils and adenoids can vibrate, causing snoring. As the airways are narrowed, with both tissues the vibrate snoring becomes louder and noisier. Snoring is not out of sleep because the throat muscles keep fixed in the back of the throat tissues. During sleep the muscles relax, allowing the tissue to collapse. The airways are narrowed or blocked in several situations, which include: the hypertrophy of the tissue in the nose, mouth or throat; tonsils grown in size are a common cause of snoring in children (like colds).
The deviated nasal septum that disrupt the airflow to the nose; the loss of the muscle tone in the neck, which allows tissue collapse, this can happen in the absence of movement or with age. Other factors that may contribute to the occurrence of snoring are: alcohol consumption, leading to the inhibition part of the brain responsible for controlling breathing, this inhibition cause excessive relaxation of the tongue and throat muscles, causing a partial obstruction of airflow; obesity, by the deposit of fat in the neck which narrows the airway; some drugs can cause drowsiness or are muscle relaxants, such as those taken for allergies, depression or anxiety.
