Hello, wonderful readers! Today, we embark on a journey that could revolutionise your perspective on stress and well-being. We’re delving into the Vagus Nerve – a mighty force in your body’s stress management, tranquillity maintenance, and healing promotion. As a hypnotherapist, I’ve witnessed the profound health transformations that can occur when we grasp and nurture this essential nerve. Let’s venture into this captivating realm together.

The Vagus Nerve an Introduction

The Vagus nerve, one of your body’s most intricate and extensive nerves, is a guardian of your well-being. It stretches from your brainstem to your abdomen, caressing vital organs like your heart, lungs, and digestive tract. It’s a key player in the parasympathetic nervous system, which is responsible for rest and digestion – your body’s calm and repair mode.


The name Vagus comes from the Latin word for ‘wandering,’ which is fitting given its extensive path through the body. The Vagus nerve influences heart rate, digestion, immune response, and even mood regulation. Essentially, it acts as a communication superhighway, relaying information between the brain and major organs. In simpler terms, it’s like a traffic controller, ensuring that all the organs in our body are working together in harmony. https://www.webmd.com/brain/vagus-nerve-what-to-know

Understanding the Impact of Prolonged Stress

When we experience stress, especially over long periods, it can significantly impact the vagus nerve. Prolonged stress keeps our body in a state of fight or flight, dominated by the sympathetic nervous system, which prepares the body for action. This continuous state of alert can weaken the vagus nerve’s ability to function effectively, leading to symptoms like anxiety, depression, digestive issues, and even cardiovascular problems.

On the other hand, the parasympathetic nervous system, regulated by the Vagus nerve, is responsible for rest and digestion-your body’s calm and repair mode.
Imagine your body as a finely tuned orchestra, with the Vagus nerve acting as the conductor. Prolonged stress is like a persistent, disruptive noise that throws the entire orchestra out of sync, making producing harmonious and healthy rhythms difficult. I’ve had clients who, after implementing Vagus nerve stimulation techniques, have experienced significant improvements in their overall well-being, from reduced anxiety to improved digestion.


Chronic stress can reduce vagal tone, which is the measure of the Vagus nerve’s activity. A higher vagal tone means the Vagus nerve is more active and can send and receive signals more effectively. This reduction impacts your body’s capacity to return to calm after experiencing stress. It also affects digestion, as the Vagus nerve significantly regulates stomach acids and digestive enzymes.

Signs of Vagus Nerve Dysfunction

Understanding the signs of vagus nerve dysfunction can help you identify when your body might be out of balance. Some common symptoms include:

  • Chronic inflammation
  • Digestive issues such as IBS (Irritable Bowel Syndrome)
  • Anxiety and depression
  • Difficulty swallowing
  • Voice changes
  • Heart rate irregularities
  • Fatigue

Recognising the signs of Vagus nerve dysfunction is a crucial step in maintaining your body’s balance. These symptoms, often overlooked or attributed to other causes, can be your body’s way of signalling an imbalance. If you experience several of them, it’s wise to consider the health of your Vagus nerve.

Exercise to Release Stress and Strengthen the Vagus Nerve

The good news is that you can incorporate simple exercises and techniques into your daily routine to help release stress and strengthen your Vagus nerve. Let’s look at a few:

Deep Breathing

Slow, deep breathing is one of the most effective ways to stimulate the vagus nerve. It can help shift your body from a fight or flight to rest. Here’s how you can practice deep breathing:

  1. Find a Comfortable Position: Sit or lie down in a comfortable position.
  2. Inhale Deeply: Inhale through your nose for a count of 4, allowing your abdomen to rise.
  3. Hold Your Breath: Hold your breath for a count of 4.
  4. Exhale Slowly: Exhale through your mouth for a count of 6, allowing your body to relax.
  5. Repeat: Repeat this process for a few minutes, focusing on the sensation of the breath.

Cold Exposure

Cold exposure can stimulate the vagus nerve, helping shift your body from a stress response to a calm state. Simple methods include:

  • Cold Showers: Gradually reduce the water temperature towards the end of your shower.
  • Face Immersion: Splash cold water on your face or immerse it in cold water for a few seconds.

Humming and Singing

The vibrations from humming and singing can stimulate the vagus nerve. Pick your favorite tune, hum along, or make a gentle “mmmm” sound. This can be done anywhere and at any time, making it an easy way to promote vagal tone.

Yoga and Tai Chi

These practices combine movement, breath, and mindfulness, all of which are beneficial for vagus nerve stimulation. Yoga poses that involve gentle twists, and inversions can be particularly effective. Tai Chi’s slow, deliberate movements also help to calm the mind and stimulate the vagus nerve.

Techniques to Help Including Somatic Breathing

Let’s delve deeper into a couple of specific techniques designed to promote vagal tone and reduce stress: somatic breathing and the “shhhh” and “mhmm” exercises.

Somatic Breathing

Somatic breathing is a form of mindful breathing that focuses on the physical sensations in your body. It helps to ground you in the present moment and can significantly reduce stress levels. Here’s a simple exercise to try:

  1. Find a Comfortable Position: Sit or lie down in a comfortable position.
  2. Scan Your Body: Take a moment to mentally scan your body from head to toe, noticing any areas of tension or discomfort.
  3. Breathe Deeply: Inhale deeply through your nose, focusing on the sensation of the breath filling your lungs and expanding your abdomen.
  4. Exhale Slowly: Exhale through your mouth, releasing any tension with your breath.
  5. Focus on Sensations: Continue this breathing pattern, paying close attention to the physical sensations in your body. Notice how your chest and abdomen rise and fall with each breath.

“Shhhh” and “Mhmm” Techniques

These simple vocal exercises can also help stimulate the vagus nerve and promote relaxation.

  • Shhhh: Close your eyes and take a deep breath in. As you exhale, make a gentle “shhhh” sound, like you are soothing a baby. Feel the vibrations in your throat and chest. Repeat this a few times, focusing on the calming effect of the sound.
  • Mhmm: Like humming, this exercise involves making a soft “mhmm” sound as you exhale. Close your eyes, take a deep breath, and let out a slow “mhmm” sound. Feel the vibrations in your head and chest, and notice the soothing effect on your nervous system.

Embrace the Power of the Vagus Nerve

Understanding and nurturing your vagus nerve can unlock a powerful tool for managing stress and enhancing your overall well-being. Incorporating these exercises and techniques into your daily routine can help you build resilience, improve your mood, and promote a state of calm and balance in your life. However, it’s important to note that these techniques are not a substitute for professional medical advice. If you’re experiencing severe or chronic symptoms, it’s always best to consult with a healthcare professional.
The vagus nerve is your body’s built-in mechanism for maintaining balance and harmony. Taking the time to care for it can improve your physical health, emotional well-being, and overall quality of life. Remember, your body is designed to heal and thrive, and the vagus nerve is crucial to that process. Take the time to care for it, and you’ll be amazed at the following positive changes.
