Difficulties with nasal breathing. Breathing through your nose is the best way to admit air in lungs, compared to breathing between your lips. Allergies, pregnancy, the cold, can rustle blood vessels in the nasal area leading to a nasal congestion or a lack of air. The result is a mouth opening and due to that an increased resistance to air intake.


Obesity. Excessive weight, too much fat in the vicinity of neck and throat induce an extension or an increased pressure on tissues surrounding air passage. Airways are consequently shrinked. Obesity is a significant factor to snoring ability.

Some drugs and alcohol  consumption. Some drugs (in particular some tranquillizers and antihistamines) and alcohol can  induce a greater relaxation of soft tissues and muscles in throat. The result is a shrinked air passage while sleeping, and thus an increased snoring.
