How to Control the Autonomic Nervous System


Meta Description: The autonomic nervous system regulates blood pressure
and respiratory rate. Such a mechanism operates without any conscious
effort by the person.

The term autonomic nervous system, originally known as the vegetative nervous system, is a branch of the peripheral neural system that controls the operation of inner organs by supplying muscular walls and glands.

The autonomic nervous system controls and governs body activities such as pulse rate, metabolism, breathing rate, pupil dilation response, urine, and libido in a mostly unconscious manner. . The fundamental method of control for the fight-or-flight reflex is this system.

Exposure to cold, breathing techniques and meditation are the three pillars of wellbeing. These three pillars work together just to give you the abilities you need to take control of the body and enhance your wellbeing.

Let’s Look Further into Autonomic Nervous System

Since the autonomic nervous system is so basic, most researchers believe that proper control originates at ganglionic, or at most, spinal regions. As a result, people are sometimes astonished to learn that brain malfunction is frequently associated with autonomic dysfunction, which could be risky.

Patients experiencing spinal transection, for instance, may experience acute hypertensive crises as a result of a weak bladder, impacted bowel, or perhaps even skin stroking. This isn’t to argue that the autonomic ganglia and spinal cord don’t contribute to a function in autonomic control. However, the supraspinal levels are where autonomic output is organized.

Between regions that receive visceral impulses and govern autonomic efferent responses, among sites that control sympathetic vs. parasympathetic nervous system outputs, and between regions that regulate autonomic regulation and somatic, endocrine, and limbic circuits, there is extensive connectivity. The core autonomic network refers to this collection of linkages as a whole.

The Autonomic Nerve System’s Structure

The autonomic nervous system controls the blood vessels, stomach, pupils, gut, liver, kidneys, salivary, bladder, lungs, heart, sweat, genitals, and digestive glands.

The autonomic nervous system is divided into two parts:

  • Sympathetic
  • Parasympathetic

When the autonomic nervous system gathers information about the organism and physical factors, it reacts by either activating or regulating physiological activities, depending on whether the sympathetic or parasympathetic divisions are active.

An autonomic nerve pathway is formed by two nerve cells. One cell can be found in either the brain stem or in the spine. Nerve fibers link it to another cell, which is part of a chain of nerve cells. Vital organs are connected to nerve fibers from all these ganglia. The sympathetic division’s ganglia are mostly found just outside of the spine on both ends. The parasympathetic division’s ganglia are typically spotted near or even in the organs they interact with.

How to Control the Autonomic Nervous System (ANS)

There are certain ways one can try to control their ANS, which are tested and proven by experts. One of which is a tVNS stimulator, which helps users calm their nerves, reducing stress, and easier ways to relax.

New findings have been made as a result of the recent study on the placement of sympathetic nerves. Autonomic systems affecting the ganglia, heart, stomach, and sensory organs are also being studied by scientists.

Due to several ideas based mostly on histochemical data and some physiologic evidence, researchers have been able to discover that the contact between a nerve ending and a receptor operates as a regional autonomy at the organ level. At the ganglion stage, cells might act as interneurons, which could provide additional controls.

Using the Vagus Nerve to Control Autonomic Nervous System

Do you ever feel like you’re losing control? As if you don’t know how to unwind? It’s something that most of us have done at some time in our lives. Discover how to self-soothe whenever you feel like your mind or body is taking over control. The sympathetic nervous system is generally linked to the sense of being out of regulation.

The element of our nervous system which activates us all into activity is the sympathetic nervous system. The nervous system will activate your fight, flight, freeze reflex if it senses a real or imagined risk.

Therefore, when there isn’t a major threat, you don’t need to activate our defense systems.  You should activate your parasympathetic nervous system, which would be the nervous system component that soothes us down.

Your parasympathetic nervous system’s most powerful nerve is indeed the vagus nerve. It works as a natural reset button for your body. Understanding how to activate the vagus nerve might help you get that tranquil, controlled sensation we all want.

In Latin, vagus signifies wandering. Because of the wandering journey, it travels first from the brain to all of the organs.  It is also your body’s longest nerve, influencing heart rate, breathing, and metabolism.

The Vagal Tone

The tension of the vagus nerve is important for parasympathetic nervous system activity. Vagal tone may be measured using heart rate variability. The pulse rate picks up a little when you take in a deep breath. This then slows down a little when you exhale. The bigger the gap between your inhaling and exhaling heart rates, the greater the vagal tone. The greater the tone, the better at calming yourself you are.

Higher vagal tone is linked to improved overall health. It improves blood sugar control, lowers the risk of cardiac arrests and cardiovascular problems, boosts metabolism, and decreases migraines. Above all, it’s linked to improved mental stability, resilience, and lifespan.

Emotional inconsistency, depression, chronic fatigue syndrome, cognitive deficits, diabetes, systemic inflammatory, and heart disease are all related to reduced vagal tone.

What Is The Best Way To Stimulate The Vagus Nerve?

Breathing that is steady, rhythmic, and diaphragmatic.

The diving reflex, which is connected with activating the vagus nerve, is stimulated by spraying cold water on your face or enjoying a cold bath. Pressing a ziplock bag full of ice cubes to your face while maintaining your breath will provide the same effect. Alternatively, put your tongue in a chilly drink.

  1. Meditation.
  • Practicing yoga.
  • The practice of speaking softly, methodically, and melodically as though calming a small child or pet is known as prosody.
  • Spend some time in nature and the great outdoors.
  • Consider other individuals in a favorable light.
  • Participate in constructive social interactions.
  • The vocal cords are stimulated by humming or producing a “voooh” or “ommm” sound, which allows for a lengthy, leisurely exhale.
  • Exhale against a blocked airway by closing your lips and squeezing your nose while trying to exhale out. It stimulates the vagus nerve by putting more pressure inside the thoracic cavity.
  • By engaging the back muscles of the neck while gently breathing, gargling stimulates the vagus nerve.
  1. Take probiotics to develop healthy gut flora.
  1. Laugh heartily! The vagus nerve is stimulated by a full hearty laugh, which is contagious!
  1. Participate in praying or meditative rituals.
  1. The vagus nerve and gastrointestinal flow are both stimulated by little exercise.
  1. The vagus nerve may be stimulated by massages, even gentle stroking around the carotid sinuses, mostly on the sides of the throat.

Other Pros of the Vagus Nerve

The parasympathetic nervous system is activated by stimulating the vagus nerve, which decreases our neurophysiological response to stress. It lowers blood pressure and heart rate. It affects the brain’s limbic system, which is responsible for processing emotions. It helps in digestion and gives you a better sense of well-being.

Whenever stress starts to build, try practicing the technique of activating the vagus nerve to reduce anxiety, depression, pressure, and a general sensation of discomfort. We encourage you to do so regularly as a preventative approach to promote higher emotional stability and better health.

The Effects of Caffeine in ANS

Caffeine is a bioactive component present in coffee, tea, and sodas, among other liquids. Caffeine causes an increase in blood pressure and sympathetic nerve output, mostly in the short term. Caffeine use regularly can reduce short-term physiological consequences.

Infrequent caffeine drinkers, caffeinated espresso promotes parasympathetic activity; conversely, decaffeinated espresso reduces parasympathetic activity. Additional bioactive compounds in decaffeinated espresso might also lead to the suppression of parasympathetic activation in caffeine addicts.

Caffeine has been demonstrated to boost work capacity and cause maximum heart rate during a difficult activity in one research when contrasted to a placebo. Caffeine’s propensity to boost sympathetic nerve output is most likely to blame for this tendency. Furthermore, the healing process after strenuous activity is delayed when caffeine is consumed before exercise.

Try Controlling Your Autonomic Nervous System in a Healthy Way

The ways discussed on how to control your ANS are pretty simple and very but attainable. Try it out yourself to help yourself with depression, anxiety, and a better lifestyle.
