I’m a 30-year-old marketing manager, and three years ago, a flu I should have recovered from left me with symptoms that never fully resolved.
For the first six months, I thought it was post-viral tiredness and that I should give it time.
Then I started fainting when I stood up. My heart would race walking from my desk to the kitchen for a glass of water. Hot showers became a problem. Standing in queues became a problem. Eventually, prolonged standing itself became difficult.
What many people do not fully understand about Postural Heart Rate Abnormalities is how disruptive even low levels of exertion can become.
I have a desk job. I sit at a laptop for a living, I’m not a nurse or a builder, and even that became something I had to ration.
A morning of back-to-back meetings could leave me unable to function for the rest of the day.
Standing presentations often left me visibly unwell and physically shaky. Some weeks, the commute itself, on my feet on a train, was the hardest physical thing I did.
Eventually, a cardiologist diagnosed me with Postural Heart Rate Abnormalities, which stands for Postural Orthostatic Rapid Heartbeat Syndrome.
The short version is that my autonomic nervous system, the system that’s supposed to handle things like keeping blood pressure stable when I stand up, no longer regulates these processes efficiently.
I’ve been working with my medical team for two and a half years now: beta blockers, increased sodium intake, compression garments, intermittent IV saline during severe symptom periods, and a cardiology team I see every six months.
None of that has changed, and I want to be clear before I go any further.
Nothing I say in this article is medical advice, and I haven’t stopped any of my therapy. I’ve just added something alongside them.
What I’ve added is a vagus nerve stimulation device.
I’d been considering it for a year, ever since my cardiologist mentioned in passing that some of his care recipients with autonomic dysfunction had told him they found it helpful.
He emphasised that the evidence remains preliminary.
He said the research is still preliminary and he couldn’t recommend it as a therapy, but he didn’t see any harm in trying it alongside my existing care.
I had a rough few weeks of symptoms in the autumn. I thought about it for a while, ordered one, and decided to keep a journal for thirty days.
Here’s what actually happened.
Day 1–4: The First Few Days
It came in a plain white box.
I clipped it onto my left ear while sitting on the sofa, because I try to minimise unnecessary standing whenever possible. The sensation was a faint tingle, not unpleasant, just present.
For three days, I noticed nothing.
My standing heart rate was still doing what it does, my energy was what it was, and the post-shower symptom flare was still a feature of my mornings.
On day four, I wore it for a longer session, around an hour, while working from the sofa. Around the forty-minute mark, I noticed something I hadn’t expected. The persistent background physiological tension I always carried, the sense of anticipating symptom flare-ups, had eased.
I’d been so used to that buzz that I’d stopped noticing it was there.
Noticing that the tension eased was the first sign that something might be happening.
Day 8–12: A Slightly Easier Morning
Mornings are hard with Postural Heart Rate Abnormalities: I usually need an hour after getting up before I feel anywhere close to functional; heart racing, lightheaded, difficulty adjusting to standing.
By the second week, I was doing a session first thing, still sitting up in bed before I tried to stand.
On day eleven, I stood up, walked to the kitchen, made my coffee, and didn’t have to sit back down. I sat down anyway out of habit, but I didn’t have to.
That was new.
The same week, my afternoon crash, which usually arrived around 2 PM and significantly reduced my functioning for the remainder of the day, was softer. I still needed a rest, but I wasn’t fully incapacitated, and I actually got through my afternoon calls instead of rescheduling them.
Symptoms like mine have been linked to autonomic dysregulation, where the autonomic nervous system, which regulates involuntary bodily functions, has difficulty regulating these functions efficiently.
Vagal tone is one part of how that system stays balanced, and lower vagal function has been associated with poorer autonomic regulation in some research.
I’m not a healthcare professional, and I don’t claim to understand the mechanism fully.
However, I did notice meaningful changes subjectively, and this journal records it.
Day 16–22: Sleep and the Smaller Wins
My sleep had been significantly disrupted for years.
Postural Heart Rate Abnormalities often do this, partly because lying down and standing up both ask the autonomic system to adjust, and partly because anxious thoughts about the symptoms keep the persistent physiological hyperarousal.
In week three, I started sleeping through the night again. Not every night, but more than I had in two years.
The cumulative effect was the most noticeable thing.
When I’d had two good nights of sleep in a row, my overall functioning improved the following day: my standing tolerance was better, my afternoon energy was steadier, and the symptom flares became less severe, and they didn’t last as long.
Other things I noticed:
- The post-shower symptom flare shortened to about twenty minutes
- I could stand long enough to make a simple meal without my heart rate climbing into uncomfortable territory
- The cognitive tiredness typically worsened around lunchtime lifted earlier, which meant my afternoon work stopped being a mental tiredness I had to work through
None of these fixed Postural Heart Rate Abnormalities.
I want to keep saying that, because it matters.
I still have Postural Heart Rate Abnormalities, I still take my medications, and I still have bad days where I can barely get off the sofa. But the bad days were less frequent, and the good moments were a bit longer.
Day 23–26: I Went Down to Review the Available Research
By week four, I wanted to understand what I was experiencing.
I gave myself an afternoon with a coffee and a stack of open browser tabs.
This was my understanding of the mechanism involved.
The vagus nerve is the body’s main parasympathetic pathway, which is the “rest, digest, recover” system. It’s the longest cranial nerve, running from the brainstem down through the neck and into the heart, lungs, and digestive system. About 80% of its fibres are afferent, meaning they send signals up to the brain. Only 20% send signals down.
The vagus nerve plays a major role in autonomic balance, the system that regulates heart rate, blood pressure, and how the body’s response to position changes. When vagal function is reduced, autonomic regulation can suffer, and the body has a harder time maintaining physiological stability during routine positional and environmental changes.
HRV, which is commonly used as a non-invasive marker of autonomic nervous system activity, has been linked with autonomic resilience and recovery in a number of studies.
Research specifically on vagus nerve stimulation for symptoms like Postural Heart Rate Abnormalities is still preliminary, and I want to be honest about that.
There’s research showing that the technology affects vagal activity, HRV, and stress reactivity. Whether and how those effects translate to symptom management for specific symptoms is something the research community is still working through.
The technology I was using is called Nurosym.
It’s an auricular vagus nerve stimulation that sends mild electrical signals through a branch of the vagus nerve that runs close to the skin in the outer ear. The signal travels up the nerve to the brainstem.
This kind of stimulation has been studied in completed scientific studies, reviews, and important analyses.
A few numbers stood out:
- A 61% increase in vagal activity
- A 35% reduction in stress-response reactivity
- Improvements in reported sleep quality (+ 30%)
- Reductions in reported tiredness and improvements in energy (- 48%)
I won’t pretend I read every paper, but it was enough to convince me there may be a plausible physiological explanation for some of the changes I noticed, even if the picture for my specific symptom is still being filled in.
Tag 30: Was sich geändert hat
I still have Postural Heart Rate Abnormalities.
I’m still on my medications.
I still have bad days, and I still structure much of my life around managing this symptom.
Aber:
- My standing tolerance is noticeably better, especially in the mornings
- The post-shower symptom flare has shortened a lot
- I'm sleeping more nights through than I used to
- The afternoon crashes are softer and shorter
- I managed a full day in the office last week, meetings included, which I'd been avoiding for months because of symptom severity
- I have more energy for the things that matter, even on the days when standing is still hard
And the one I really didn’t expect, I’m not bracing for the next bad moment as constantly as I was. Some of that constant anticipatory stress has reduced.
Why Your Body Stays Stuck (And How This Helps)
The vagus nerve is the longest cranial nerve in the body.
It runs from the brainstem down through the neck and into the abdomen, branching into the heart, lungs, and digestive system. About 80% of its fibres are afferent, meaning they send signals to the brain, and only 20% are efferent, sending signals away from the brain.
The vagus nerve plays a major role in autonomic regulation, the system that handles things like heart rate, blood pressure, digestion, and how the body adjusts to changes in position or activity.
When that system has been disrupted, following illness or other physiological stressors, the body can struggle with the routine physiological adjustments normally handled unconsciously.
This is one reason post-viral symptoms, autonomic dysfunction, and chronic tiredness can show up together.
They can share an overlapping autonomic nervous system dysfunction.
Auricular vagus nerve stimulation works by sending mild electrical signals through a branch of the vagus nerve that runs close to the skin in the outer ear. The signal travels up the nerve to the brainstem, which can help support the parasympathetic side of the nervous system.
It’s not a therapy, and it shouldn’t replace any care your health professional has prescribed. It’s a tool that may support the autonomic nervous system regulation alongside existing care.
A Note on the Practical Side
If you’re thinking of trying one, here are a few things I wish someone had told me.
First, talk to your health professional before adding it to your routine, especially if you have a diagnosed symptom.
I wasn’t surprised when I brought it up, but I wouldn’t have wanted to review potential contraindications independently.
I paid full price, around €700.
It’s not cheap.
The other thing that made me commit was the 30-day money-back guarantee. If it hadn’t worked, I’d have sent it back, and that reduced the perceived financial risk for me in the first place.
You wear it clipped to your ear, and sessions run from 15 minutes up to two hours. I do an hour in the morning while still in bed and another hour in the evening on the sofa.
The sensation is a faint tingle, not painful.
You can wear it during most normal sedentary activities that isn’t a workout or a shower.
Meine ehrliche Meinung
I’ve spent three years building a life around a symptom that took the old one apart, and I’ve tried a lot of things along the way. Some helped, some didn’t.
This was one of the few interventions that felt meaningfully helpful for me personally.
It hasn’t given me my pre-Postural Heart Rate Abnormalities life back, because that’s not how this works, and I don’t think anyone has a tool that does. But it’s given me steadier mornings, longer stretches of feeling closer to functional, and a bit more energy for the people and the work in my life.
I still live with the symptom every day.
But for the first time in a long time, I feel like I’m more capable of managing it consistently.
That’s the most honest summary I can give.
Recovery Doesn't Always Mean Doing More
Sometimes the goal isn’t to push harder; it’s to help the body recover more effectively.
Nurosym was developed to support the vagus nerve, an important part of the autonomic nervous system involved in stress regulation, recovery, and cardiovascular adaptation.
See why growing numbers of researchers and healthcare professionals are interested in vagus nerve stimulation as a tool for supporting nervous system health.
