Why You Snore

 

The cause of snoring is that when the upper airway of your nose or throat is partially blocked during sleep, the restricted breathing airflow makes noises.

While sleeping, the muscles of the soft palate and tongue relax, plus during the inhalation phase of breathing cycle, the lung sucks the air through the soft palate and back of the relaxed tongue, causing the soft tissues to close the airway.

When the airway narrows, while open, it causes a whistle sound. Once the muscles near the throat are aged, the soft tissues collapse and obstruct the airway.
