What causes snoring is a question that can be answered multiple ways. From an anatomical standpoint, snoring is caused by a partially closed upper airway (the nose and throat). Everyone’s neck muscles relax during sleep, but sometimes they relax so much that the upper airway partly closes and becomes too narrow for enough air to travel through to the lungs. When this happens, it means that a person isn’t taking in enough oxygen for the body to perform its important functions. The brain then sends a signal to the body to wake up to get the oxygen it needs, likely resulting in the person waking up throughout the night without realizing it.
Why do people snore?
Why do some people snore and others don’t? Those who have enlarged tonsils, an enlarged tongue or excess weight around the neck are more prone to snoring. And structural reasons like the shape of one’s nose or jaw can also cause snoring. The snoring sound itself is a result of the narrowing of a person’s airway, which causes a throat vibration and the snoring sound. No matter the reason, 40% of normal adults snore regularly,1 whether they realize it or not.
