The vagus nerve's job is to regulate your Parasympathetic nervous system.
Sympathetic and Parasympathetic divisions typically function in opposition to each other.
Their hope was they wouldn't stimulate their Parasympathetic nervous system and
decrease their ability of their bodies to utilize their sympathetic nervous system.
Interestingly, this is one area of the body that can be affected both negatively or positively by both your Parasympathetic and sympathetic nervous systems.
Self-manifestation of a particular type of response is rare,
mixed reactions with predominance of adrenergic or Parasympathetic parts of the nervous system are more common.
Shame stimulates the Parasympathetic nervous system often leading to a decrease in energy,
motivation, and a withdrawal from human contact.
Anything that triggers more Parasympathetic nervous system activity decreases the stress response,
and what does this likely differs across people.
Other research has found an association between cardiovascular disease and
decreased Parasympathetic nervous system control of the heart.
However, many instances of sympathetic and Parasympathetic activity cannot be ascribed to"fight" or"rest" situations.
They are simply intense anxiety,
and the symptoms are real expressions of the sympathetic and Parasympathetic nervous system activating and regulating.
These systems were once thought to oppose each other-
the sympathetic and Parasympathetic.
The dominance of the Parasympathetic branch is why you feel content
and sleepy after a giant lunch.
It stimulates the Parasympathetic nervous system,
which, in turn, soothes the body's stressful fight or flight response.
The sympathetic and Parasympathetic nervous systems have links to important organs
and systems in the body;
Green landscapes aren't only beautiful, but also engage our Parasympathetic nervous systems and lower our stress level.
Spending just a few minutes
consciously breathing can help trigger the Parasympathetic nervous system and reset us to a more balanced state.
If you can do this,
then the second branch of the automatic nervous system, the Parasympathetic branch, can switch on.
It's responsible for the fight-or-flight response, the functional opposite of the Parasympathetic nervous system.
Some have compared yin and yang to the sympathetic and Parasympathetic nervous systems.
So, in addition to triggering the Parasympathetic nervous system,
the researchers hypothesize that music also stimulates gastrointestinal activity, which, in turn, might facilitate and speed up the absorption of blood pressure drugs.
While the sympathetic nervous system governs the fight-or-flight response, the Parasympathetic nervous system is involved with"rest
and restore," or regulating the body at rest, Thurston explained.
As the chemical stimulates the Parasympathetic nervous system,
it brings on increased motility(movements) of the gastrointestinal tract, and if the poison travels from the stomach to the small bowel it will cause further damage.
When we breathe deeply and fully, involving not only the breast, but also the abdomen, lower back, chest,
it helps our Parasympathetic nervous system, which is responsible for the process of relaxation.
This stimulates the calming, centering Parasympathetic nervous system
and settles down the fight-or-flight stress-response sympathetic nervous system that jiggles the spotlight of attention this way and that, looking for carrots and sticks.
Yogic Breath relieves stress, refreshes the mind, and activates the Parasympathetic nervous system,
encouraging a calmer, more balanced state of being overall.
When the sympathetic part of the nervous system,
the“fight-or-flight” impulse, is operating, it suppresses the functioning of the Parasympathetic branch and the vagus.
Referring to some of their previous research,
they say,"We have observed classical music activating the Parasympathetic nervous system and reducing sympathetic activity.".
For example, the sympathetic nervous system controls the heart, blood vessels,
and respiratory system, while the Parasympathetic nervous system controls our ability to sleep,
eat, and digest food.
The danger here is not only that the Parasympathetic nervous system is strained and recovery is compromised,
but that the child will come to have strong negative associations with the activity in question.
The ANS can be split into two roughly equal branches-
the sympathetic and the Parasympathetic, or, as it is memorised by every first year medical student,
the“fight-or-flight” and the“rest-and-digest” branches.
