Snoring is caused by the vibration of the soft palate and uvula, occurring when the airway becomes obstructed during sleep. Several things can obstruct the airway and cause you to snore, including allergies drinking before bed, being overweight and having large tonsils or a deviated septum.
If you snore now and then, you probably have nothing to worry about. But chronic snoring can be a sign of sleep apnea, a more serious sleep disorder. People with sleep apnea stop breathing in their sleep – sometimes up to 100 hundred times an hour – for one minute or longer.
Left untreated, sleep apnea can increase your chances of serious health conditions like high blood pressure and heart disease. At a minimum, you may feel groggy in the morning or unable to concentrate during the day.
