Snoring is a wheezing noise one produces while resting at night. For those wondering what causes snoring, it occurs when an obstruction in the airway causes the tissues in the throat to vibrate. This may happen because of several options like anatomy, smoking, drinking, obesity, or an underlying sleep problem like obstructive sleep apnea. To treat this problem, treatment options like avoiding drinking, quitting smoking, CPAP treatment, oral appliances, and surgery are recommended.
