Vagus Nerve Exercises for Digestion

When it comes to your health, the foods you eat are just one piece of the puzzle. Including health-promoting foods in your diet is important, but equally important is setting your body up to digest what you feed it optimally. Vagus nerve exercises for digestion ensure your body can make the most of what you put on your plate.

Enhance Digestion Through Vagus Nerve Exercises

Digestion plays an important role in sustaining overall health and well-being. The vagus nerve is a key player in the parasympathetic nervous system responsible for regulating various bodily functions, including digestion. 

The vagus nerve is the longest cranial nerve in the body that runs from your brain to your large intestine. The health of the vagus nerve can directly impact digestion and therefore has an impact on digestive symptoms such as gas, bloating, irregular bowel movements, acid reflux, and stomach pain. 

While food choices and lifestyle habits also play a role in digestive health, emerging research suggests that targeted exercises to stimulate the vagus nerve can significantly improve digestion. 

The Vagus Nerve and its Role in Digestion

The vagus nerve, also known as the “wandering nerve,” is the longest cranial nerve in the human body, extending from the brainstem down to the abdomen. 

It serves as a communication highway between the brain and the digestive system, orchestrating various digestive processes, including gastric secretion, gut motility, and nutrient absorption. 

Furthermore, the vagus nerve plays a crucial role in the gut-brain axis, facilitating bidirectional communication between the gut and the brain, influencing mood, appetite, and overall digestive health. 

This connection explains why the thoughts and feelings you experience can contribute to digestive symptoms. Think back to the last time you were nervous about a big event, speaking in public, or a first date. 

Those “butterflies” you experienced in your stomach are an example of your vagus nerve and the gut-brain connection at work. 

Signs of Vagus Nerve Dysfunction

When the vagus nerve function is compromised, it can show up as various digestive issues including:

  • Slow digestion or gastroparesis
  • Acid reflux and heartburn
  • Irritable bowel syndrome (IBS)
  • Constipation or diarrhea
  • Bloating and excessive gas
  • Appetite dysregulation and food cravings

Given its central role in digestion, optimizing vagus nerve function can alleviate these symptoms and promote gastrointestinal health.

Vagus Nerve Exercises for Digestion

Fortunately, there are several simple yet effective exercises designed to stimulate the vagus nerve, thereby enhancing digestive function. Incorporating these exercises into your daily routine can promote relaxation, reduce stress, and improve overall gut health.

Let’s explore some of the vagus nerve exercises for digestion:

Deep Breathing Techniques

Deep breathing exercises, such as diaphragmatic or belly breathing, activate the vagus nerve by engaging the parasympathetic nervous system. 

To perform diaphragmatic breathing, sit or lie down comfortably, place one hand on your abdomen, and the other on your chest. Inhale deeply through your nose, allowing your belly to rise as you fill your lungs with air. Exhale slowly through your mouth, feeling your stomach fall. Repeat this process for 1-3 minutes, focusing on the rhythm of your breath.

Meditation and Mindfulness Practices

Next, mindfulness, meditation, and other relaxation techniques are great vagus nerve exercise for digestion. They can stimulate the vagus nerve and promote digestive function by reducing stress and anxiety. Set aside a few minutes each day to practice mindfulness meditation, focusing on your breath or sensations within your body. 

Additionally, progressive muscle relaxation, guided imagery, and yoga can promote the relaxation response, encouraging optimal digestion.

Cold Exposure

Cold exposure, such as cold showers or cold applied to the face and neck, can improve heart rate variability, a marker of stress adaptation. Start by splashing cold water on your face or taking a brief cold shower, gradually increasing the duration and intensity over time. Cold exposure stimulates the vagus nerve, boosts circulation, and enhances immune function, contributing to overall well-being.

Singing, Chanting, and Humming

Vocal exercises, including singing, chanting, or humming, stimulate the muscles in the throat connected to the vagus nerve. Even humming a tune or chanting “om” can create a calming effect and support the vagus nerve.


Gargling with warm salt water or engaging in vocal exercises that involve gargling can stimulate the muscles at the back of the throat connected to the vagus nerve. Incorporate gargling into your daily oral hygiene routine or as part of your vocal warm-up exercises to promote vagal activation and support digestive health.

Laughter Therapy

One study has demonstrated that laughter can be included in the list of vagus nerve exercises for digestion. Laughter is indeed the best medicine, as it triggers a cascade of physiological responses, including vagal activation. 

Watch a funny movie, spend time with friends who make you laugh, or engage in laughter yoga to reap the digestive benefits of laughter therapy. Laughter stimulates the vagus nerve, boosts mood, relieves stress, and strengthens social connections.

How to implement vagus nerve exercises for digestion

If your goal is to improve digestion by strengthening the vagus nerve, here are some practices to implement before you sit down to eat:

  • Hum “Happy Birthday” twice
  • Take 3 deep inhales and exhales
  • Gargle with warm salt water before eating breakfast in the morning


In conclusion, the vagus nerve plays a pivotal role in regulating digestive function and maintaining gastrointestinal health. By incorporating targeted exercises to stimulate the vagus nerve into your daily routine, you can enhance digestion, alleviate digestive symptoms, and promote overall well-being. 

Whether through deep breathing techniques, meditation practices, vocal exercises, or cold exposure, cultivating vagal tone can optimize digestive function and support a thriving gut-brain connection. 

Embrace these vagus nerve exercises for digestion as integral components of your holistic approach to digestive health, to improve your well-being from the inside out.
