Daily vagus nerve stimulation to help you snap out of survival mode.

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.

We’ve heard this quite a lot from yōjōers, and potential yōjōers have said they wouldn’t want another chatbot in their lives. We realized we hadn’t done enough to show that yōjō well-being coaches are human, that real fingers are tapping away on the other side of the chat, and that online coaching sessions are between humans. So we sent a film crew to interview Ayesha, yōjō’s well-being coach, to show that every yōjōer has a gloriously human professional supporting their journey.

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.

1. 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?
2. 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?
3. 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?
4. 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?
5. 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?
6. 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.
