The vagus nerve, often called the "wandering nerve" due to its extensive reach throughout the body, plays a vital role in regulating the parasympathetic nervous system—our body's natural relaxation response. By understanding how the vagus nerve works and learning techniques to stimulate it, we can harness its power to calm our minds, improve our emotional resilience, and foster self-soothing practices.
The vagus nerve is the longest cranial nerve in the human body, connecting the brainstem to various organs, including the heart, lungs, and digestive system. It’s a critical part of the parasympathetic nervous system, which helps us "rest and digest."
When the vagus nerve is activated, it lowers heart rate, reduces blood pressure, and promotes relaxation. Its influence extends to emotional regulation and social connection, as it also impacts areas of the brain involved in mood and stress management.
Vagal tone refers to the health and responsiveness of the vagus nerve. A higher vagal tone is associated with better emotional regulation, reduced anxiety, and improved physical health. Conversely, a low vagal tone is linked to stress, inflammation, and mood disorders.
To improve vagal tone, one must engage in activities that stimulate the vagus nerve and support its function.
Here are evidence-based practices or tools to activate the vagus nerve and foster calmness:
Deep Breathing
Slow, deep breaths, especially diaphragmatic breathing, can directly stimulate the vagus nerve. Aim for a 4-6 count inhale and a longer exhale (6-8 count) to enhance relaxation.
Cold Exposure
Splashing your face with cold water or using cold compresses can activate the dive reflex, which engages the vagus nerve and slows the heart rate.
holding a piece of ice, taking a cold plunge, dumping ice cold water on your head, your arm your foot.
Humming, Singing, or Chanting
Activities that involve vocal cords, such as humming or chanting, stimulate the vagus nerve due to its connection to the throat and vocal muscles.
You can hum, mumble, gargle, goo goo with a baby, play a harmonica, sing opera, anything that will vibrate the throat.
Meditation and Mindfulness
Practices that focus on awareness and relaxation, like mindfulness meditation, have been shown to increase vagal tone.
Yoga and Tai Chi
These practices integrate breathing, movement, and mindfulness, making them excellent for vagal stimulation.
Gut Health
The vagus nerve plays a role in the gut-brain axis. Consuming a diet rich in fiber, probiotics, and fermented foods can support vagal function and overall health. Learn about acid vs alkaline foods, especially if you have gut issues.
Laughter and Positive Social Interaction
Genuine laughter and warm social connections can enhance vagal tone and promote feelings of safety and relaxation.
Watching comedy shows, or funny videos, or funny youtube channels are helpful. take a break and laugh for 5 minutes.
Massage and Acupressure
Gentle massage, especially around the neck and ears, can stimulate the vagus nerve. Techniques like craniosacral therapy may also help.
Beyond vagus nerve stimulation, cultivating self-soothing strategies can be helpful for emotional resilience. Here are a few methods:
Grounding Exercises
Engage your senses by focusing on what you can see, hear, touch, taste, or smell. For example, the 5-4-3-2-1 method encourages you to identify five things you see, four you feel, three you hear, two you smell, and one you taste.
Progressive Muscle Relaxation (PMR)
Tense and then relax muscle groups in your body, starting from your toes and moving upward, to release tension and calm the mind.
Journaling
Writing down your thoughts and feelings can help you process emotions and gain perspective.
Visualization
Imagine a peaceful place or memory in vivid detail to shift your mental state and reduce stress.
Aromatherapy
Scents like lavender, chamomile, and bergamot can have calming effects on the nervous system.
Research supports the benefits of vagus nerve stimulation for both physical and mental health. For example:
A 2018 study in Frontiers in Neuroscience highlighted the vagus nerve's role in reducing inflammation and improving mood.
Research in Psychological Science demonstrates that higher vagal tone is linked to better emotional regulation and resilience.
Studies on mindfulness and yoga consistently show improvements in vagal tone and stress reduction.
