Most people who breathe through their mouth are snorers. This happens because the air that flows through the mouth causes the tissues in the throat to vibrate. The vibration causes friction between the tissues in your throat leaving it sore when you wake up.

This inflammation could potentially worsen the obstruction causing the individual to snore even more during the night.Next
