The roof of the mouth is innervated by several nerves, including the trigeminal nerve (CN V) and the glossopharyngeal nerve (CN IX), both of which are mixed nerves that carry both sensory and motor information.
The trigeminal nerve is responsible for sensation in the front part of the roof of the mouth, while the glossopharyngeal nerve supplies sensation to the back part of the roof of the mouth.
When the tongue is in the proper posture, pressing against the palate (roof of the mouth), it activates these parasympathetic cranial nerves, which can have a calming effect on the body.
The parasympathetic nervous system is responsible for rest and digestion, and activation of these nerves can help reduce feelings of stress and anxiety.
In addition to activating the parasympathetic nerves, pressing the tongue to the roof of the mouth can also activate the muscles in the throat and neck.
These muscles help to keep the airway behind the mouth open, which can be helpful for people who snore or have mild sleep apnea.
Overall, pressing the tongue to the roof of the mouth can have several beneficial effects on the body, including promoting relaxation and improving breathing during sleep.
One way to exercise the habit of pressing the tongue to the roof of the mouth is through conscious awareness and practice:
1. Start by becoming aware of the position of your tongue throughout the day. Notice when it is resting at the bottom of your mouth versus when it is touching the roof of your mouth.
2. When you notice that your tongue is resting at the bottom of your mouth, gently press it against the roof of your mouth.
3. Practice holding your tongue in this position gradually increasing the amount of time you can hold it there comfortably.
4. Repeat this throughout the day, gradually making it a habit.
In addition to this, a Functional Activator is a great tool that can be used to improve tongue posture.
