SLEEP AND SNORINGSnoring is caused by air trying to squeeze through a narrowed or blocked airway.

Obstructive sleep apnea is a condition in which the flow of air decreases during breathing while you are asleep because the airway has become narrowed.

Normally, the upper throat remains open enough during sleep to let air pass by.

However, when the muscles in the upper throat relax during sleep, the airway is narrowed and breathing is reduced or blocked completely. Ask Dr. Eric Levine, if an oral appliance might reduce your snoring.
