What Causes Snoring?
Snoring happens when air cannot move freely through your nose and mouth during sleep. The airway narrows, the soft tissue vibrates, and that vibration is the sound. In more severe cases the airway can become blocked altogether, which is known as obstructive sleep apnea.
Many things contribute to snoring: age, nasal and sinus problems, carrying extra weight, alcohol, smoking, some medications, and the position you sleep in.
