Snoring is caused by the obstructed air movement during breathing while asleep. It is sometimes caused by the relaxation of the uvula muscle and soft palate to partly block the airway, or a result of jaw misposition, or even obesity and ingesting certain drugs which cause muscle relaxation. Although snoring is often considered a negligeable nuisance, sometimes it could prove to be a lifestyle impairment such as sleep deprivation, or a disturbance to your sleeping partners.
