My yōjō Journey and What I Didn’t Expect
When I first started using yōjō back in December, I approached it the way I approach most wellness tools: open-minded but measured. Here’s what happened.
As a GP, I understand the science behind vagus nerve stimulation. I know the vagus nerve is the body’s master regulator, that it connects the brain to the body, and that it governs that all-important shift from ‘fight-or-flight’ into ‘rest-and-digest’. I know the mechanism, but I don’t think I really expected the impact.
I definitely wasn’t prepared for how much of a difference I would feel.
How I yōjō
My routine is simple.
Every night, when I go to bed, I grab my yōjō. I apply the gel to the earpiece and pop it in my ear. I find a comfortable intensity and then just let the gentle electrical pulses do their thing.
I also use it during the day when I remember. This is becoming more frequent because the benefits have become harder to ignore.
The sensation took a little getting used to — little electrical zaps that you have to set to your comfort level — but it quickly became something I looked forward to rather than something I had to remind myself to do.
What surprised me most
Sleep. Sleep. Sleep.
I’ve always been someone who can lie awake, mind whirring, tossing and turning for hours before finally dropping off. In the first few days of using yōjō, I noticed I was falling asleep faster.
At first, I put this down to coincidence, a good few days, or a placebo effect. But now, several months in, I can say with confidence that it is none of these.
On the nights I use yōjō versus the nights I don’t, there is a noticeable difference.
My Garmin data backs this up, too: sleep quality has genuinely improved, not just my perception of it. And that matters to me as someone who values having objective data alongside improvements in how I feel.
Getting to sleep faster has been the biggest win.
Anyone who knows that particular frustration of lying in the dark, wide awake, brain refusing to switch off, will easily understand just how significant this has been.
A shift in how I think about my nervous system
Something I didn’t anticipate was how using yōjō would make me more intentional about my parasympathetic nervous system more broadly.
Understanding something intellectually and actively working on it are two different things. yōjō has brought vagal tone into my daily awareness in a way that’s spilled over into other habits.
I now use the physiological sigh regularly — a double inhale through the nose followed by a long exhale — which is one of the fastest ways to manually activate your parasympathetic nervous system. It’s the kind of technique I’ve always known about, but yōjō has made me more motivated to layer these practices together.
I feel more in control of my own nervous system regulation, and that feeling of agency is something I hadn’t expected to value as much as I do.
Would I recommend it?
I started this journey curious. I’m continuing it as a genuine convert.
Whether you’re someone who struggles to wind down at night, feels chronically overstimulated, or simply wants to feel more grounded in your own body, yōjō offers something that is both accessible and, in my experience, genuinely effective.
The science was always there. And now I’ve felt it for myself.

How Do You Know If Your Nervous System Is Dysregulated?
"I just feel a bit off, not myself, but I don't really know why." Here’s why.
As a wellbeing coach and health psychology specialist, I've worked with hundreds of clients — executives running global teams, athletes preparing for competition, busy working parents spinning a dozen plates — and one of the most common things I hear, in slightly different words each time, is: "I just feel a bit off, not myself, but I don't really know why."
What strikes me is how rarely people connect that feeling to their nervous system.
It's not their fault. Nervous system regulation isn't something we're taught about in school, and the symptoms often don't feel serious enough to bring to a healthcare professional.
So when something feels off, most people don't know where to look for answers. And they end up tolerating a low-grade version of themselves for months, sometimes years, before joining the dots.
So before we get into this further, let’s do a simple check-in to see if your nervous system might be a little out of sorts.
A few questions to ask yourself
Sit with these for a moment. There's no scoring system, and this isn’t a diagnosis. Just be really honest about whether any of these describe you right now, and if there’s a pattern across more than one area.
- Do you find it hard to fall asleep even when you're exhausted? Do you wake at 2 or 3 am with a busy mind? Or, do you get a full night’s sleep yet wake unrested?
- Do you feel "tired but wired", too depleted to do much and too revved up to rest? Do you crash in the afternoons, then get a second wind late at night?
- Is your concentration patchier than it used to be? Are you losing words mid-sentence, walking into rooms and forgetting why, or finding tasks that used to be easy harder?
- Are you more reactive than usual — tearful, snappy, anxious — over things that wouldn't normally land that hard? Or the opposite: flat, numb, a little disconnected from yourself and the people around you?
- Is your jaw tight? Shoulders up by your ears? Heart occasionally racing for no clear reason? Has your digestion become unpredictable? Do bloating, reflux, irregular bowels, sensitivities seem to be multiplying?
- When something stressful happens, how long does it take you to genuinely come back down? Hours? Days? Or does it feel like you never quite return to baseline at all?
If you're nodding along to several of these — particularly across more than one category — it's worth taking seriously. This is what a dysregulated nervous system tends to look like in real life. Not dramatic. Not always alarming. Just a steady accumulation of small signals.
Why this happens — even when you're coping
Here's the part that often lands hardest with my clients: you can be coping and be dysregulated at the same time. In fact, that's the most common presentation I see.
You're still showing up, still hitting deadlines, still being a good parent, a reliable friend, a strong performer. From the outside — and often from the inside too — it looks like things are working. And they are, but your body is keeping score. And it's beginning to show you, in quiet ways, that the system needs some help.
To understand why, it helps to know a little about how your autonomic nervous system works.
Your autonomic nervous system has two main branches, the sympathetic (fight-or-flight) and the parasympathetic (rest-and-digest). A balanced system switches fluidly between the two throughout the day. You ramp up for a meeting, then come back down. You handle a stressful conversation, then return to baseline. That movement between states is what we mean by regulation.
Dysregulation isn't about being stressed. It's about losing the ability to come back down. When the body lives in a state of low-grade activation for long enough — from demanding work, caring responsibilities, illness, unresolved emotional load, or simply years of pushing through — the system stops returning to baseline between stressors.
Your sleep gets lighter. Your digestion gets touchier. Your mood gets thinner. Your thinking gets foggier. None of it is dramatic in isolation. All of it points to the same underlying issue.
The symptoms above, while seemingly random and tied to character flaws, are just your physiology responding to you running hot for too long without a proper reset.
Where to go from here
The first piece of work is recognition, which is what this article has really been about. And it is what asking yourself those questions at the top will help ignite. And if they have helped you identify something worth addressing, there is good news.
Your nervous system can relearn any flexibility it may have lost.
Quitting your job, ditching your caring responsibilities, or running away to a tropical island won’t help you rebalance your nervous system long-term. Teaching your system that it's safe to come down will. Consistently engaging in small daily rituals that activate your rest-and-digest response helps your body to learn how to switch back into this mode more easily and fast-track you back to feeling more like yourself.

Five Easy Ways to Support Your Vagus Nerve
Your vagus nerve plays an important role in helping your body manage stress, digestion, and recovery. Here are five simple, everyday ways to support it.
The vagus nerve is a key part of the body’s system for calm and regulation. It helps influence heart rate, digestion, immune responses, and how the body adapts to stress. Vagal activity is associated with resilience and recovery.
In today’s fast-paced world, ongoing stress can place extra demand on the nervous system. When the body struggles to shift out of a constant “on” state, this may contribute to challenges such as poor stress regulation, inflammation, or digestive discomfort.
There are clinically studied ways to stimulate the vagus nerve, including non-invasive vagus nerve stimulation (nVNS). Alongside these, there are also simple, natural practices that may help support vagal activity as part of everyday life.
Embrace the cold
Brief cold exposure can encourage activation of the parasympathetic nervous system. This might include a short cold shower, a dip in cool water, or even splashing cold water on your face. These experiences can prompt the body to shift toward a calmer, rest-and-digest state.
Breathe mindfully
Breathing is one of the few automatic bodily processes you can consciously influence. Slow, deep breathing that engages the diaphragm can help signal the body to relax, supporting heart rate regulation and parasympathetic activity.
Try this
Place one hand on your chest and the other on your stomach.
As you breathe in through your nose, allow your belly to rise while keeping your chest relatively still.
Exhale slowly through your mouth.
This style of diaphragmatic breathing can help support vagal function and encourage a calmer physiological state.
Sing, hum, chant … or gargle
The vagus nerve has branches that connect with the muscles of the throat and vocal cords. Activities such as singing, humming, chanting, or even gargling can create gentle vibrations in this area, which may help stimulate vagal pathways.
Get moving
Physical activity supports the nervous system as well as the muscles. During exercise, the body becomes more alert, while recovery afterward relies on parasympathetic activity to restore balance. Over time, this process can help train the nervous system to move more efficiently between states of activity and rest.
Regular movement is associated with better stress recovery and overall nervous system health.
Socialize and laugh
Social connection plays a meaningful role in nervous system regulation. Spending time with others, sharing positive experiences, and laughing can support parasympathetic activity and are linked to lower stress levels and improved heart rate variability.
Supporting your vagus nerve doesn’t require dramatic lifestyle changes. Small, consistent practices can help create the conditions for better balance and resilience over time.
For those seeking a more targeted approach, non-invasive vagus nerve stimulation (nVNS) is a clinically studied option designed to stimulate the vagus nerve safely and effectively.

What Everyone Gets Wrong About Burnout
Burnout isn’t a character flaw. It’s biological. Here’s what’s really happening beneath the surface, and how to restore balance.
Burnout is a state of emotional, physical, and cognitive exhaustion caused by prolonged stress. It’s marked by depleted energy, reduced motivation, and a sense of detachment from work or life.
Most conversations about burnout circle the same three ideas:
- You’re no longer aligned with your work.
- The cult of productivity won’t let you rest.
- Your mindset needs a reset.
All true — but they miss the real point.
Burnout feels philosophical, even spiritual, but at its core, it’s biological. Down-and-dirty, animal biology. It’s what happens when your body’s survival systems forget how to stand down.
Your stress response was built for short bursts of action. A chase. A threat. A deadline. When those bursts never end, the stress never stops — and your body forgets how to switch off, and it’s “all systems go” all the time.
At first, it’s just overdrive. Then, it becomes dysfunctional.
Cortisol floods your system. Your immune response activates. Low-grade inflammation spreads quietly through your tissues. Your brain reads this chemical chatter as a sign of danger. Even when you’re sitting still, your body’s braced for attack.
That’s burnout: a body in fight-or-flight, running on fumes, trying to save energy for life-saving tasks that never come. Your mood drops, your focus fades, you start conserving — not because you’re weak, but because your body thinks it’s protecting you.
And because the stress keeps coming, the inflammation keeps burning. The stress-inflammation-stress cycle loops and loops.
The good news? Low-grade inflammation is manageable — even reversible — when the nervous system is taught how to regulate again.
That’s what yōjō helps people do.
We use science-backed tools — vagus nerve stimulation, biofeedback, and personal coaching — to restore balance to your nervous system and help it remember how to rest, recover, and reset.

Itutu: A Philosophy of Calm
Mastering this mindset helps you tackle life’s little stresses before they snowball.
Chronic stress fuels inflammation. Inflammation fuels disease. And before you know it, you're caught in a cycle that wears down your body, ages you faster, and drains your energy. In short, stress is your enemy. The best way to deal with an enemy is to choose only those battles you can win.
There are the big stresses in life and the small stresses. We hardly need to explore the big stresses; we all know them. There’s no winning against them. They just are, and we do our best to accept them. The small stresses, however, we can conquer the minute they kick up a fuss.
These are the less remarkable, less noticeable stresses. Those dozen or so situations and happenings that tense up your mind just a smidge, like a person tightening a guitar string. Just a little at a time. The tardy bus, the broken shoelace, the spilled coffee, the rude coworker, the winding queue, the stolen seat, all piling on top of each other, turning that mind string until it is so tense your entire being develops a distinct, steely twang.
There may be many, and they may sometimes be hard to see, but one West African approach to life can help you thwart these little enemies and stop them from strumming your nerves with their fingers.
It’s called “itutu.” It is a way of seeing minor stresses and worries that takes the sting out of them.
As The School of Life explains in their video, A Philosophy of Calm, itutu “denotes a particular approach to life: unhurried, composed, assured, and unflappable.” Among the Yoruba people, to “have itutu” is to embody coolness — to meet frustration with poise and to remain untouched by the noise of small misfortunes.
This calm isn’t a divine gift; it can be learned. It’s the fruit of knowing, as the Yoruba say, that some things belong to “àṣẹ” — the natural order — and lie beyond our control.
Anger arises when we overestimate our power to change external reality. Itutu arises when we see the limits clearly and choose peace within them.
Modern science would call this emotional regulation, the ability of the prefrontal cortex to modulate limbic reactivity. When you practice the qualities embodied by itutu, you train your nervous system to stay out of fight-or-flight.
Over time, this translates into measurable benefits: lower cortisol, steadier heart rate variability, reduced inflammation, and potentially improved longevity.
Cultivating this mindset makes you resilient. You learn to save your energy for what truly matters, and your calm becomes your default setting.

Frogs, Frankenstein, and VNS
The inspiration for Frankenstein is worse than fiction, but instrumental in understanding how nerves work.
A steel table, metal probes, and life-giving lightning are the images accompanying the creation of Frankenstein’s monster. Mary Shelley’s Frankenstein is a glimpse into very real scientific pursuits of the 18th century that formed the foundations of our understanding of nerves and muscle tissue, including the vagus nerve.
While 8-foot human scrapbooks weren’t plaguing Europe, scientists in the 17th and 18th centuries were experimenting with animal reanimation, using electricity. Shelley spent years studying these scientific breakthroughs and took inspiration from the findings when writing Frankenstein.
Science seems to have a fascination with frogs, and the history of understanding nerves has amphibians to thank for their role in early experimentation.
Jan Swammerdam was a 17th-century naturalist and philosopher known for creating the Bybel der Natuure (Bible of Nature) — a collection of studies on insects which, at the time, included frogs. Swammerdam’s interest in frogs had theological and scientific goals: he wanted to prove that all creatures were created by God and governed by the same biological rules. Swammerdam used similar muscle experimentation methods on frogs as those used on larger animals like cats and dogs. He exposed the leg nerves and used sharp instruments to stimulate contractions, showing a closer link between frogs and humans than was previously thought.
Luigi Galvani’s inquiry into reanimation started with a frog, a static electricity machine, and a scalpel. A frog’s leg nerves were exposed near a charged electrical machine when Galvani’s wife touched a nerve with a scalpel, causing the leg to spasm. Noting that the scalpel had been near the static electricity machine shortly before his wife had used it to touch the frog, Galvani formed and tested his theory that electrical force could travel along the nerves to the muscles, causing them to contract. He called this “animal electricity”.
Galvani also found that nerves from one frog could be attached to the muscles of another, and that the muscles from the second frog responded when the nerves were stimulated.
Shortly after Galvani published his findings, another professor of physics named Allesandro Volta disputed the notion of “animal electricity”, causing controversy in the field. By repeating Galvani’s experiments with frogs, Volta concluded that the key to nerve stimulation was in agitating them with two differing types of metal. The more dissimilar the metals, the more intense the reaction. Galvani would later disprove this by using two rods made of the same type of metal to cause muscle contractions. The result of their scholarly dispute? Both were partially right and wrong: there is no “animal electricity”, but nerve stimulation doesn’t require two differing metals to achieve.
Galvani’s nephew, Giovanni Aldini, continued his uncle’s work by publicly animating the corpses of executed criminals. Aldini inserted metal rods into the corpses and stimulated muscle movement with electricity, demonstrating a macabre display of galvanism and leading to questions about bringing back the dead.
These galvanist pursuits weren’t the only inspiration for Shelley — the author cites Erasmus Darwin (grandfather to Charles Darwin) in two editions of her work.
Erasmus Darwin was a physician, botanist, and poet, and amongst his publications on plants and evolution, he wrote on reanimation in dead microorganisms.
Arguably, the most influential figure in crafting Frankenstein was Sir Humphry Davy, a friend of Shelley’s father who allegedly inspired the character Victor Frankenstein.
Davy was a professor of chemistry at the Royal Institution in London, with crowds overfilling his lecture hall to watch his experiments. Davy used Volta’s invention—the electric pile—to investigate and prove that electricity generation depends on a chemical reaction. Shelley used some of Davy’s lectures as dialogue for Victor Frankenstein and tried to capture the professor's passion for understanding nature and his drive to master it.
Non-invasive vagus nerve stimulation (nVNS) is a form of mastery over nature. Short bursts of electrical energy are passed through the vagus nerve to relax the stress response, improve nervous system function, recalibrate certain regions in the brain, and control inflammation. What scientists learned about the effect of electrical impulses on nerves from their experiments hundreds of years ago, we use now to regulate the digestive system, improve mood, and manage chronic pain disorders via the vagus nerve.
Fortunately, nVNS can be done at home, sans steel table and metal probes.
