6 Ways to Activate the Parasympathetic System

The Autonomic Nervous System is made of the Sympathetic Nervous System and Parasympathetic Nervous System.

The Sympathetic System is necessary in times of exercise, or if fast physical action is needed (“Fight or Flight”).

Like all things in nature, we want to achieve balance. This blog post will discuss the benefits of activating the parasympathetic nervous system, why to do it and how to do it.

Working with the autonomic system is truly the playground of energy medicine. The Autonomic Nervous System is controlled by the vagus nerve and spinal cord. This system is very responsive to stress. During times of stress, either prolonged or brief, the Sympathetic Nervous system will govern bodily functions. The Sympathetic Nervous system will change the endocrine system to prepare for a threat. This means the hormone system will be producing more “stress hormones” (such adrenaline and cortisol) constantly.

How do you know when it’s time to activate the parasympathetic system?

  • Insomnia
  • Agitation
  • Restlessness
  • Anxiety
  • Fast heartbeat
  • Feeling lightheaded
  • Feeling ungrounded
  • Increasing pain levels
  • Digestive issues
  • Sexual dysfunction

Experiencing any of these signs or symptoms means that likely your sympathetic nervous system is running the show. It’s time to find balance.


1. Grounding Meditation While Standing

Standing with your feet firmly in place preferably barefoot for 1 to 3 minutes can help slow down your nervous system and let the parasympathetic system activate. In the book 21 Day Meditation Journey, we practice doing a few poses standing to activate Earth energy. Focusing your energy on your legs and feet can help to slow down racing thoughts. Do this simply by taking several deep breaths while standing and if your balance allows with your eyes closed.

2. Hip Openers to Relax The Mind and Body

Yoga uses asanas (Yoga Poses) that focus on the hips to relieve stress.  The hip joints are weight bearing joints.  The hips, the hip girdle and lower back are also a place where many of us hold stress in our bodies.  This can be felt by tightness in the hips, trouble going from standing or sitting, or back pain.

Freeing up the hip joints through stretches will allow the mind and body to relax deeply.  These poses can be modified for comfort of course.  

Yoga Poses To Open the Hips

How to Modify These Poses

  • Sit on a blanket or block in Half-Lotus for comfort
  • Use Blocks or Blankets underneath the knees in Cobbler’s Pose
  • Sit on Blankets or Blocks in Yogi Squat
  • Dead Pigeon Pose on the Back is an alternative to Pigeon Pose

3. Deep Belly Breath

The Parasympathetic Nervous System can be activated with deep breaths into the belly. Breathing is controlled primarily by the Autonomic Nervous System. We can take conscious control of breath be taking deeper, slower breaths.

Taking deep Belly Breaths doesn’t require a formal meditation practice. You can do this even while reading this blog post.

Breath Into the Belly Now

  • Sit or stand straight, aligning
  • Loosen your clothing if needed
  • Inhale by initiating the breath by expanding the belly first, then the chest
  • Exhale first from the chest then the belly, squeeze the belly in.

4. Slow Down Your Breath

Breathing too rapidly is a a habit we all fall into easily. Hyperventilation, which is taking in too much oxygen, can occur if breathing is occurring only in the chest. During times of stress and anxiety, particularly if you’re sitting for prolonged periods, this can easily occur.

Breathing deeply and slowly allows the Parasympathetic system to engage. This can calm the mind and body.

Breath Counting Exercise

5. Express Your Feelings

The Autonomic Nervous System never lies. If you are hanging on to thoughts of pain, hurt, or resentment those emotions are being stored within your body. Finding a way to safely and effectively express your emotions will allow you to release stress and let your parasympathetic nervous system increase its activity. There’s no need to confront anyone or start a fight.

Using a journal, or a piece of paper you can safely discard, write down your feelings that are creating discomfort. Doing this will relief your body of the tension of unexpressed emotions.

Mindfulness Writing Exercise

6. Meditate to Quiet the Mind

Meditation is a powerful tool to calm the Sympathetic Nervous System (“Fight or Flight”) and engage the Parasympathetic Nervous System.

Meditation can be a simple moment of mindfulness of 3 minutes, or a formal practice.

What is the Autonomic Nervous System?

Understanding the autonomic system is a powerful healing tool. The autonomic nervous system controls every function in the body. In the most recent Art of Healing Podcast, we discuss what is blood pressure.

Many patients often wonder why they have high blood pressure. Many others also wonder why they have digestive issues when they feel nervous (such as nausea or diarrhea).

What is the autonomic nervous system?

Understanding the nervous system helps you understand your body.

Within all of us, there is a system the controls heart rate, respiration, digestion, waste elimination, and sexual function. This same system influences our moods, and can control how we feel moment to moment.

The Autonomic Nervous System deeply impacts our experience in reality. Understanding this system will give you the keys to healing your mind and body.


What is the Autonomic System?

The cognitive functions such as thinking, emotions and voluntary bodily actions are governed by the Central Nervous System. The Central Nervous system consists of the brain and spinal cord. The brain and spinal cord send information to the body and receive information back through sensory neurons.

While we can control how fast we breath (such as slowing down the breath during meditation), it is difficult to consciously control the heart rate. It is nearly impossible to consciously change digestion, for instance, we can not control how fast peristalsis (contractions of the muscles of the intestines) occur.

The Autonomic Nervous System controls the bodily functions that are not under conscious control This sounds deceptively simple. Respiration, circulation, digestion, immunity and reproduction all most be coordinated in order for the body to function in a healthy way. This must be balanced against the bodies need to move in order to acquire energy, expend energy or escape a threat.


The Autonomic Nervous System is divided into two systems, the Parasympathetic Nervous System, and the Parasympathetic Nervous System.

In general, these systems oppose each other. One is always active, and only decreases it’s activity if the opposing system generates more signals.


“Each system is dominant under certain conditions. The sympathetic system predominates during emergency ‘fight-or-flight’ reactions and during exercise…the parasympathetic system predominates during quiet, resting conditions.”

— McCorry L.K., Physiology of the Autonomic Nervous System


Parasympathetic Nervous System

There are times in which the body needs to rest and recover, such as after meals, when it’s time to sleep, or simply relax.  There is no significant demand on the body to exert energy for survival. 

This mode of operation is when the parasympathetic system is dominant.  This system will influence the body to slow down the heart rate, increase digestive activity, and overall create a feeling of being relaxed.  This is the feeling we all have relaxing in our favorite chair reading a book for example.

The Parasympathetic Nervous System allows the mind and body to rest, digest and recover. When the body can slow down, the digestive system is able to absorb nutrients and eliminate waste effectively. The reproductive system can operate naturally, allowing for a natural libido that will ensure healthy sexual drive. The cardiovascular system, through the parasympathetic nervous system, will direct blood flow to the organ to ensure the normal bodily functions can perform at their best.

Function of the Parasympathetic Nervous System

  • Increases blood flow to digestive tract to encourage waste elimination
  • Encourages blood flow and nerve function ton augment sexual functioning
  • Increases blood flow to the digestive tract to improve motility of digestive system and nutrient absorption
  • Slows down the heart rate

Sympathetic Nervous System

Rest and recovery are necessary, but there are times in which we need to be active and kinetic.  We need to be alert, aware, and reflexes need to be at their peak.  When driving in heavy traffic, for example, the body needs to be able to react quickly to avoid a car accident.  Blood flow needs to be directed to the extremities to augment fast action if needed.  The heart should pick up speed in anticipation of a possible threat.  The pupils will dilate to improve vision.  This is when the sympathetic part of the sympathetic nervous system will dominate.  

The Sympathetic Nervous System controls blood flow, reflexes, and temperature of the limbs.  Reflexes are an important survival tool for the living body. 

The Sympathetic Nervous System operates mostly outside of the nervous system. This system is designed to run on speed and reflex. It is the Sympathetic Nervous System that governs reflexes. One example is if you reach for an object that’s too hot to touch, you will notice you withdraw your hand before you even register the pain of heat.

The Sympathetic Nervous system is activated in times of exercise but also in stress. The design of the sympathetic nervous system operates with speed, and does not require the input of the brain. This system is able to activate the adrenal glands in times of crisis. The “fight or flight” reaction is when some sort of stimuli that creates fear engages the Sympathetic Nervous system, which will cause the release of adrenaline from the adrenal glands. This powerful reaction can be life saving in times of trauma. It is a very necessary system for survival.

Function of the Sympathetic Nervous System

  • Decreased blood flow to the digestive tract
  • increased blood flow to the extremities
  • Increases heart rate and respiration
  • Turns sweat glands on
  • Dilates pupils to improve vision

What does the Autonomic System Control?

All of the organs of the body are controlled by the autonomic system.  The skeletal muscles and bones of the limbs are controlled by the sympathetic system.  Since the “Fight of Flight” of the body usually requires increased blood flow to the limbs, ths Sympathetic System exerts control in this area.

The organs of the chest and abdomen are controlled by both the Sympathetic and Parasympathetic nervous systems.

We often don’t realize our body must be able to respond to external stimuli rapidly. If there’s a threat heading our way, our brain may take several minutes to process the threat. Fortunately, we have intelligent bodies that can take over the process of running, hiding, or fighting. For this reason, the sympathetic nervous system, which governs the body’s ability to respond to external threats rapidly, does not need to communicate much with the brain.

The parasympathetic nervous system governs the body’s ability to digest food, have sexual intercourse, and eliminate waste, as well as influences the cardiovascular system to slow down. From this description we can tell that the parasympathetic system is best to run the body system in times of rest, relaxation or recovery.

Why Understand the Autonomic Nervous System?

The Autonomic Nervous System influences all of the glands of the body. Control of hormonal production is heavily influenced by the Autonomic Nervous System.

I have the blessing of working with individuals with their bodies on a daily basis. Reflecting on this topic has reminded me of the true, miraculous nature of the human body.

The Chakra System, knowledge imparted from the ancient healing system of Ayurveda can be demystified by analysis of the Autonomic System.

It is for this reason I am embarking on my next project with my heart and soul. This project will journey even deeper into demystifying the mind-body connection by understanding the Heart Chakra.

Stay tuned for next week in this series in which we will discuss more in depth be sympathetic any parasympathetic nervous systems.

The next few months at Healing Arts will be full of exciting content.
