Snoring is caused by the relaxation of the muscle in the soft palate (roof of the mouth), tongue and throat. The tissue in the throat can get so relaxed that it can end up blocking the airway and vibrate as the air rushes through the passage. If the airway is narrower, the vibration will be more intense and the snore will be louder. But worry not, as there are home remedies that will help you combat this problem without any torment of side effects.
