How Snoring Starts
When you drift into deep sleep, your throat muscles relax. This can narrow the airway, making airflow less smooth and creating the conditions for snoring.
Why It Gets Louder
As the airway narrows, air has to move through a smaller space. This can increase tissue vibration, making snoring louder and more disruptive.
How Difiney Helps
Difiney gently positions the lower jaw forward to help keep the airway more open. With smoother airflow and less tissue vibration, sleep can feel quieter and more comfortable.
