Some people do not understand the difference between snoring and sleep apnea. The human body is built in many different forms. Obese people can have more blocking tissues in the esophagus which narrow the air passageway. This blockage of the passageway can also be experienced by someone who has a large uvula. There are also other reasons that can cause snoring like: big tonsils, a long tongue, large adenoids, a deviated nasal septum, and a small lower jaw. For these men and women, the likelihood of having snoring problems is greatly increased.
Things like cigarettes and asthma can also increase the likelihood of acquiring a snoring issue.
The way you position your body during the night is also a concern. When gravity pulls the tongue and jaw down to the back of the mouth due to sleeping on one’s back, the passageway becomes smaller and therefore, may lead to snoring. Using devices like stop snoring mouthpieces can help.
