<human>: Is it true that the snoring is caused by the air that is blocked in the nasal passage?
<bot>: Yes, it is true that the snoring is caused by the air that is blocked in the nasal passage. The airflow through the nasal passages can be restricted due to the swelling of the tissues around the nose and mouth during sleep. This causes the airways to narrow and vibrate as you breathe. This vibration causes noise which is known as snoring.
