In our demanding modern lives, feelings of stress, anxiety, and being overwhelmed are increasingly common. These aren’t just mental states; they are physiological responses managed by our nervous system. A key player in this internal regulation is the vagus nerve. Understanding how to influence this nerve can be a transformative tool for managing stress and enhancing your overall well-being.
This guide will explore the function of the vagus nerve and provide a comprehensive overview of evidence-based techniques—both clinical and at-home practices—to “reset” your nervous system. By learning to improve your vagal tone, you can build greater resilience to stress, reduce inflammation, and foster a stronger connection between your mind and body. At ROZE BioHealth, our experts, like physiotherapist Sandra Serrano, specialize in these integrative methods to help you achieve lasting health.
What is the vagus nerve?
The vagus nerve is the longest and most complex of the twelve pairs of cranial nerves that originate in the brain. Its name comes from the Latin word for “wandering,” which aptly describes its extensive path from the brainstem down through the neck and chest to the abdomen, connecting with nearly every major organ along the way.
As the primary component of the parasympathetic nervous system—often called the “rest and digest” system—the vagus nerve plays a crucial role in regulating a vast array of involuntary bodily functions, including:
- Heart rate and blood pressure
- Digestion and gut motility
- Breathing patterns
- Inflammatory responses
- Mood and emotional regulation
- Sweating and detoxification
Essentially, the vagus nerve acts as a two-way communication highway, sending signals from the brain to the body and, just as importantly, relaying information from the organs back to the brain. This biofeedback loop is fundamental to maintaining homeostasis, the body’s state of internal balance. A healthy, well-functioning vagus nerve helps you transition smoothly from a state of stress (sympathetic “fight or flight” mode) back to a state of calm and recovery (parasympathetic “rest and digest” mode).
Vagal Tone: A Measure of Resilience
The effectiveness of your vagus nerve is often described in terms of “vagal tone.” High vagal tone is associated with a strong ability to regulate internal states efficiently. Individuals with high vagal tone tend to recover more quickly from stress, have a lower resting heart rate, and exhibit better emotional regulation.
Conversely, low vagal tone indicates that the vagus nerve is not functioning optimally. This can leave the body stuck in a sympathetic “fight or flight” state, making it difficult to relax and recover. Over time, poor vagal tone can contribute to a host of chronic health issues.
Signs of Low Vagal Tone
When the vagus nerve isn’t functioning properly, the body’s ability to regulate itself is compromised. This can manifest in a wide range of physical, emotional, and cognitive symptoms. Recognizing these signs is the first step toward addressing the root cause and improving your nervous system’s resilience.
Common indicators of low vagal tone include:
- Chronic Stress and Anxiety: A persistent feeling of being on edge, overwhelmed, or unable to relax.
- Digestive Issues: Problems like bloating, constipation, gastroparesis, or symptoms of Irritable Bowel Syndrome (IBS), as the vagus nerve heavily influences gut function.
- High Resting Heart Rate: An elevated heart rate even when at rest can signal a dominant sympathetic nervous system.
- Difficulty Swallowing or a Frequent Gag Reflex: The vagus nerve controls muscles in the throat involved in these actions.
- Mood Swings and Depression: Dysregulation of the nervous system is closely linked to mood disorders.
- Chronic Inflammation: The vagus nerve helps regulate the body’s inflammatory response, and low tone can lead to systemic inflammation, contributing to conditions like autoimmune diseases and chronic pain.
- Fatigue: A constant state of exhaustion that isn’t relieved by rest, often because the body is stuck in a high-alert state.
- Dizziness or Fainting: The vagus nerve helps manage blood pressure, and dysfunction can lead to sudden drops upon standing (vasovagal syncope).
- A Hoarse or Weak Voice: The nerve innervates the larynx (voice box), and poor function can affect vocal quality.
If you consistently experience several of these symptoms, it may be beneficial to explore techniques to improve your vagal tone.
Evidence-Based Clinical Techniques for Vagus Nerve Stimulation
For individuals with significant symptoms of low vagal tone or chronic conditions, targeted clinical treatments can provide a powerful reset for the nervous system. At ROZE BioHealth, our skilled physiotherapists, including Sandra Serrano, utilize advanced, non-invasive techniques to directly stimulate the vagus nerve and restore balance.
Transcutaneous Vagus Nerve Stimulation (tVNS)
Transcutaneous Vagus Nerve Stimulation (tVNS) is a non-invasive therapy that involves applying a mild electrical current to the skin over a branch of the vagus nerve, typically on the ear. This gentle stimulation activates the nerve, sending signals to the brainstem that help shift the nervous system into a parasympathetic “rest and digest” state.
How it works:
A small device with an ear-clip electrode is placed on the tragus or cymba conchae of the outer ear. The device delivers a controlled electrical pulse, which patients usually feel as a light tingling sensation. Sessions are typically performed in a clinical setting and last for a scheduled duration.
Benefits of tVNS:
- Reduces symptoms of depression and anxiety
- Lowers inflammation markers
- Improves heart rate variability (a key indicator of vagal tone)
- Can alleviate symptoms of chronic pain and migraines
Manual Therapies
Specialized manual techniques performed by a trained physiotherapist can also effectively stimulate the vagus nerve. These hands-on approaches focus on releasing physical tension in areas where the vagus nerve travels, such as the neck, chest, and abdomen.
Our expert, Sandra Serrano, integrates osteopathic principles and visceral manipulation to address restrictions that may be impeding vagal nerve function. By gently mobilizing the soft tissues and organs around the nerve’s pathway, these therapies can improve signaling and promote a state of deep relaxation.
When to Seek In-Clinic Treatment
While at-home practices are beneficial for general well-being, certain situations warrant professional guidance and clinical intervention. If you experience persistent symptoms of low vagal tone that significantly impact your quality of life, or if you have a chronic condition like an autoimmune disorder, fibromyalgia, or treatment-resistant depression, in-clinic treatments can offer more targeted and effective relief.
At ROZE BioHealth, we recommend a consultation if:
- Your symptoms are severe or chronic.
- At-home practices do not provide sufficient relief.
- You have been diagnosed with a condition linked to vagal nerve dysfunction.
- You want a structured, personalized plan that combines clinical therapies with guided lifestyle changes for optimal results.
Take the Next Step Toward Nervous System Balance
Understanding and supporting your vagus nerve is a powerful step toward reclaiming control over your health. By integrating these simple yet profound techniques into your life, you can cultivate a more balanced, resilient, and vibrant self.
