Why do some people snore?
Snoring is a common problem that can range from a mildly annoying noise to a serious medical problem. It is caused by the vibration of tissues in the airway during breathing during sleep.
The main cause of snoring is extra fatty tissue in the neck and throat. This can narrow the airways and promote snoring. A long soft palate or elongated uvula can also narrow the airways and cause them to vibrate during breathing. Enlarged tonsils, especially in children, can block the airways and cause snoring.
Weak muscles can narrow the airways, especially when the muscles relax during sleep. This can be made worse by alcohol use, sleeping pills or old age. Allergies, colds or abnormalities such as a deviated septum can restrict airflow through the nose and lead to snoring. Nasal polyps can also obstruct airflow.
Sleeping on your back can cause the base of the tongue and soft palate to slide toward the back of the throat, blocking the airways and causing snoring.
Sleep disorders such as obstructive sleep apnea (OSAS) can also cause snoring. OSAS is a serious condition in which the airways are repeatedly blocked during sleep, leading to snoring, respiratory arrest and disturbed sleep. Age, male gender, smoking and alcohol are also triggers for snoring.
