Your Vagus Nerve Holds the Key to Calm — Here's How to Support It Naturally
You've probably heard people talk about "nervous system resets" and wondered what that actually means in practice.
Well, there's a specific part of your nervous system that holds more influence over how you feel day to day than most people realise. It's called the vagus nerve. And the research emerging around it is genuinely fascinating.
Pull up a chair — this one's worth knowing about.
What Is the Vagus Nerve?
The vagus nerve is the longest nerve in the human body. It wanders — quite literally, that's what "vagus" means in Latin — from your brainstem all the way down through your neck, chest and abdomen, connecting your brain to your heart, lungs, gut and immune system along the way.
It's the main highway of your parasympathetic nervous system — the part of you responsible for rest, digestion, recovery and calm. When your vagus nerve is functioning well, your body can shift easily between alertness and relaxation. When it isn't, you can get stuck — locked in a state of chronic stress or exhaustion that no amount of willpower can simply think its way out of.
Sound familiar? You're not alone.
Why Your Vagus Nerve Matters More Than You Think
Here's what's really striking. Poor vagal tone — the term for how well your vagus nerve is actually functioning — has been linked to a surprisingly wide range of conditions:
Chronic stress and anxiety
Depression and mood disorders
Chronic pain and inflammation
Fibromyalgia and widespread pain
Poor sleep and fatigue
Digestive problems including IBS
Cardiovascular irregularities
Weakened immune function
Brain fog and poor concentration
Burnout and emotional exhaustion
If you read that list and thought "that sounds like me" — you're in good company. Many of the most common reasons people seek out complementary health support trace back, at least in part, to a nervous system that's struggling to regulate itself.
The really good news? Vagal tone isn't fixed. Your vagus nerve responds to the right inputs — and improving it produces real, measurable changes in how you feel.
What the Research Shows
Interest in the vagus nerve has genuinely exploded in recent years — and some of the findings are remarkable.
A landmark clinical trial — the RECOVER trial, running from 2019 to 2025 — followed 214 people with severe, treatment-resistant depression. These were people who had lived with depression for an average of 29 years and had already tried around 13 different treatments without success. Using an implanted device to directly stimulate the vagus nerve, researchers found sustained improvements in mood, daily functioning and quality of life over 24 months of follow-up.
Now — that's a medical intervention for a severe clinical condition, and it's a very different thing from what we do at Ashanti. But what it tells us is important: the vagus nerve is a genuine lever for mental and physical wellbeing, and stimulating it produces real, measurable results. That principle extends well beyond implanted devices.
Separate research has consistently shown that non-invasive approaches to vagal support — including breathing techniques, sound therapy and bio-electrical frequency therapy — produce meaningful improvements in heart rate variability (HRV). HRV is the most reliable marker of vagal tone and nervous system health. Higher HRV is associated with better stress resilience, improved mood, reduced pain sensitivity, deeper sleep and stronger immune function.
A double-blind, placebo-controlled trial published in 2025 found that PEMF therapy applied non-invasively to the neck produced significant improvements in sleep quality and anxiety levels by modulating autonomic nervous system activity — specifically by stimulating the vagus nerve. A separate randomised controlled pilot study found that a single PEMF session produced significant increases in all heart rate variability parameters — indicating a direct parasympathetic effect on the nervous system.

Natural Ways to Support Your Vagus Nerve
The vagus nerve responds beautifully to gentle, consistent input. Here are the approaches with the strongest evidence behind them:
Slow, Deep Breathing
Breathing slowly and deeply — expanding your belly rather than your chest — is one of the most direct ways to activate your vagus nerve. Around six breaths per minute has been shown to significantly increase HRV and shift your nervous system toward calm. Even five minutes a day makes a real difference.
Humming, Singing and Chanting
This one surprises people. The vagus nerve connects directly to the muscles of your throat and vocal cords — so humming, singing, chanting or even gargling sends a direct signal along the vagus nerve to your brain. Simple, free, and backed by research.
3. Cold Water Exposure
Splashing cold water on your face or finishing your shower cold triggers what's called the dive reflex — a rapid parasympathetic response mediated by the vagus nerve. Brief cold exposure has been shown to increase vagal tone and reduce inflammation. Not for everyone, but worth knowing about.
4. Mindfulness and Meditation
Regular mindfulness practice produces measurable increases in HRV over time. The effect builds with consistency — the more regularly you practice, the stronger the vagal tone response. Apps like Insight Timer offer hundreds of free guided sessions if you're just starting out.
5. Frequency Therapy
Bio-electrical frequency therapy — including rife frequency programs, PEMF and plasma therapy — works directly with the body's electromagnetic environment to support nervous system regulation. Research into PEMF has demonstrated measurable parasympathetic responses, including significant increases in heart rate variability, following frequency sessions.
What makes frequency therapy particularly interesting for vagal support is that it requires absolutely nothing from you. No practice. No discipline. No physical effort. You simply arrive, recline and rest — while the frequencies do the work your nervous system has been waiting for permission to do.
Supporting Your Vagus Nerve at Ashanti Frequency Healing
At Ashanti we offer personalised frequency programs specifically designed to support nervous system regulation — including dedicated vagus nerve programs using rife frequency therapy.
Every client begins with a New Client Intake Session where we take the time to really understand what your nervous system is asking for. From there we design a program tailored specifically to you — which may include vagus nerve frequencies alongside additional frequencies for anxiety, stress, sleep or whatever else your body needs support with.
Individual sessions are delivered in our Grafton office using a combination of delivery methods depending on your program and your needs:
TENS pads — direct contact delivery targeting specific areas
Plasma therapy — frequencies delivered through a plasma field, no contact required
PEMF — pulsed electromagnetic field delivery combining targeted and systemic support
Sessions are completely passive. You simply recline comfortably in our studio while the frequencies do their work. Nothing invasive. Nothing physically demanding. Just you, your body, and the right frequency support.
For those wanting an affordable introduction, our Group Frequency Lounge runs every Saturday morning in Grafton from just $45 — where scalar field frequencies are delivered throughout the entire treatment space. A gentle, low-commitment way to experience frequency therapy for yourself.
Remote quantum delivery via DNA sample is also available for clients who are unable to attend in person.
Your first step is a New Client Intake Session — a relaxed, unhurried conversation where we take the time to understand what your nervous system is asking for and design a program tailored entirely to you.
