Every time your tongue lifts to the roof of your mouth, it pulls on the
vagus nerve.
The same nerve that runs your gut, your heart, and your stress response.
The muscle doing the lifting is called the palatoglossus. It runs from
the side of the tongue up to the soft palate, and it's directly
innervated by the vagus.
When the tongue rests up, the palatoglossus contracts. That contraction feeds the vagus.
Digestion moves. Inflammation drops.
The body calms.
When the tongue sits on the floor of the mouth, which happens with any
mouth breathing the palatoglossus stays offline.
The vagus loses its steadiest upstream signal.
Gut motility slows.
Bloating shows up.
Anxiety rises.
The gut begins at the palate, long before it reaches the stomach.
In addition to this, a Functional Activator is a great tool that can be used to address tongue position, so the vagus stays stimulated overnight, when no amount of conscious effort can hold it in place. https://posturepro.co/products/functional-activator?utm_source=facebook&utm_medium=paid_social&utm_campaign=posturepro&utm_content=functional_activator&utm_term=prospecting
