What causes the airway to close during sleep?
There are several reasons why this would occur.
The upper airway could become blocked due to:
- The muscles around your airway relaxing too much during sleep, which blocks sufficient air from getting through. This narrow airway causes a vibration in your throat, which creates the sound of snoring.
- The weight of your neck narrowing the airway
- Inflamed tonsils, or other temporary reasons
- Structural reasons, like the shape of your nose, neck or jaw
