What causes Snoring?
When obstruction occurs in the nose — due to narrow nasal passages, nasal valve collapse, deviated septum, or congestion from a cold or allergies – air has trouble flowing in and out of your nose and the trapped air causes the throat to vibrate. Someone with healthy nasal breathing can move air in and out of the lungs through your nose with less resistance, reducing the vibrations that cause snoring.
Healthy nasal breathing also causes the air you breathe to be less turbulent (it’s smoother, like a gentle breeze). This makes your throat less likely to vibrate. Think of holding your thumb over the end of a garden hose. The water moves much faster and much more chaotically than if you don’t place your thumb there. If you can’t get enough air in through your nose, your nose acts like the thumb on the garden hose and creates turbulent air. This is more likely to make your throat vibrate and cause snoring.
You may be thinking, “I don’t breathe through my nose when I sleep, I breathe through my mouth”. For many people, nasal obstruction causes challenges with breathing through the nose, and mouth breathing becomes the only option. But mouth breathing also causes snoring. This is because when you breathe through your mouth, your tongue relaxes and shifts further back in your mouth and throat, making it more prone to vibrations, which results in snoring.
