Getting Started with Vagus Nerve Stimulation

🧠 What is the vagus nerve? (In plain English)

Your nervous system has two big modes. One is the accelerator: "fight or flight," the sympathetic system that gets you ready for danger. The other is the brake: "rest and digest," the parasympathetic system that slows your heart, switches on digestion, and lets your body repair.

The vagus nerve is the main cable of that brake.

It's the longest of your twelve cranial nerves. It starts in the brainstem, runs down both sides of your neck beside the carotid artery, and branches out to your throat, voice box, heart, lungs, liver, stomach, and intestines. The name comes from the Latin word for "wandering," and it wanders almost everywhere.

Here's the part most people never hear: about 80% of its fibers carry information upward, from your body to your brain. The vagus nerve is how your brain knows whether your gut is calm, your heart is steady, and you're safe. That's why a gut problem can feel like anxiety, and why a slow breath can quiet a racing mind. The signal runs both ways.

What "vagal tone" means

You'll hear the phrase vagal tone a lot. Think of it as how well your brake works. With good vagal tone, you get stressed and then you come back down, quickly. With low vagal tone the accelerator stays pressed: you lie awake wired, digestion stalls, your heart races at small things, and recovering from stress takes hours instead of minutes.

The hopeful part, and the reason this whole website exists, is that vagal tone is trainable. It responds to practice the same way a muscle responds to exercise.

🩺 Is it actually your vagus nerve?

Before you buy anything or start a routine, answer the more useful question: is the vagus nerve actually your problem? Almost every symptom has other possible causes. What points to the vagus nerve is a pattern, several of these drifting in the same direction at once:

🛠️ Every way to stimulate the vagus nerve

"Getting started" usually means one thing: you want to stimulate this nerve. Good. There are a lot of ways to do it, and they fall into four levels, from things you can do in the next five minutes to dedicated technology.

Start at Level 1 no matter what. Devices work best on top of the free basics, not instead of them.

1. 1
   FREE · START TODAY

   Your own body

   • Slow breathing with a long exhale (in for 4, out for 6–8)
   • Humming, gargling, singing, chanting: they vibrate the vagus branches in your throat
   • Cold water on the face, or a cold pack on the side of the neck
   • Plus movement, laughter, morning sunlight, and time with people you feel safe around

   These work through the vagus nerve's own built-in reflexes. They're free, safe, and they do most of the heavy lifting. Your first-week plan is below, and there's a morning priming routine when you want more.

2. 2
   LOW-COST TOOLS

   Simple tools that make the habits stick

   • The Nemuri breathwork necklace: a battery-free pendant whose tuned internal channel adds gentle resistance to lengthen your exhale, anywhere
   • Sleep hypnosis audio on a pillow speaker, for calm, screen-free nights
   • Hour of Power, our free affirmation audio for a steady daily practice
   • Vibration plates, rebounders, red light, and more on our top products list
3. 3
   ELECTRICAL

   Ear-clip and TENS-style stimulators (tVNS)

   Transcutaneous electrical vagus nerve stimulation uses a small device that clips onto the ear and sends a mild current into the ear's branch of the vagus nerve. It's non-invasive and increasingly easy to find. The ear branch is a smaller, more indirect target than the nerve in your neck, so the effect tends to be gentler.

   Not to be confused with implanted VNS, a surgical device prescribed by doctors for conditions like epilepsy and treatment-resistant depression. Everything on VagusHub is non-invasive.

4. 4
   ULTRASOUND

   Ultrasound vagus nerve stimulation (uVNS)

   This is where my own work focuses. A small amount of gel goes on the side of the neck, a handheld ultrasound unit sits over the vagus nerve, and a session runs for a few minutes. Most people feel little more than a faint warmth, then notice their heart slow, their breath deepen, and their shoulders drop.

🪜 Your first week: free, starting today

Don't try ten things at once. Do these, in this order, and add the next one only when the one before it feels automatic.

1. 1
   START TODAY

   The long exhale

   Breathe in through your nose for 4 seconds, out for 6–8 seconds, with a short pause at the bottom. Five minutes, three times a day. The long exhale is the signal that tells your brainstem the threat is over and the "rest and digest" system can take the wheel.

2. 2
   ADD THIS WEEK

   Hum after meals

   One minute of low, steady humming after each meal, and a good gargle when you brush your teeth. Rest two fingers beside your windpipe while you hum: that buzz is the vagus nerve's branch to your voice box. You're stimulating a nerve you can literally feel.

3. 3
   YOUR RESCUE BUTTON

   Cold on the face

   When you're spun up, splash cold water on your face or hold a cold pack on the side of your neck for 15–30 seconds. It triggers the "diving reflex," the fastest downshift your body has.

4. 4
   EVERY MORNING

   Rate your day, 1 to 10

   Score your sleep, energy, mood, and calm each morning. It takes ten seconds. You'll often see the numbers move before you feel the change, and on the hard days the numbers are what keep you going.

The free guidebook picks up from here with the full step-by-step ladder, plus two 30-second tests that let you feel your vagus nerve working.

🔊 Ready for a device? Start with these 3 pinned posts

When people decide they're ready for ultrasound, the same questions come up every single time. So I answered them once, properly, and pinned the answers to the top of Vagus Skool, our free community. Read these three in this order:

A quick safety note: electrical and ultrasound devices aren't for everyone. If you have a heart condition, a pacemaker or another implanted device, epilepsy, or you're pregnant, talk to your doctor before using one. Start gently, and stop if anything feels wrong.

👥 You don't have to figure this out alone

The single biggest accelerant we've ever seen isn't a device or a technique. It's community. People who do this alongside others stick with it, and the people who stick with it are the ones who get results. Pick one of these, or both:
