What is snoring?

Snoring - norm or pathology?

Ideally, people should not snore at all, because appearance of this sound phenomenon clearly points to the dynamic interruption of air flow in the upper airways, which causes a decrease of lung ventilation. Nevertheless, all people on earth may have episodes of snoring during sleep.

What causes OSA?

Formation of snoring and sleep apnea is associated primarily with a reduction of soft parts tone of upper respiratory tract, impaction of the tongue, which leads to a narrowing of the airways so that the passage of air into the lower parts becomes impossible. As a result the breath interruption (apnea) happens and blood oxygen content is reduced. In consequence of this the brain sends a signal, the sleeper wakes up, his breathing is restored. After fast falling asleep, everything is repeated again. Against apnea the proper sleep becomes impossible; the body is experiencing a sharp shortage of oxygen, which violates the activities of all organs and systems. Obesity is a major risk factor of snoring and Sleep-Disordered Breathing (SDB).
