ABOUT SNORING
Snoring is the sound you make when your breathing is blocked while you are asleep. The sound is
caused by tissues at the top of your airway that strike each other and vibrate. Snoring is
common, especially among older people and people who are overweight.
To reduce snoring
・ Lose weight if you are overweight.
・ Cut down or avoid alcohol and other sedatives at bedtime.
