When the autopilot goes out of tune.
Palpitations on standing, dizziness, temperature instability, fatigue, fog in the head. Separately each has an explanation. Together they point to one thing: autonomic regulation.
What it looks like day to day.
If you recognise three or more, it is worth looking not at each complaint separately, but at the system that connects them.
- 01The pulse jumps sharply on standing
- 02You feel dizzy when you get up quickly
- 03You are hot, then cold, without cause
- 04Fatigue that does not match the load
- 05Fog in the head that comes and goes
The complaint is on the surface. The control sits deeper.
The autonomic nervous system governs everything you do not think about: pulse, blood pressure, temperature, digestion, pupils. In dysautonomia that governance becomes unstable — it is not absent, it answers imprecisely.
The best-known form is POTS: on standing, the pulse rises disproportionately. But the picture is rarely just one thing. That is why patients with dysautonomia usually pass through several specialties before anyone looks at the system as a whole.
Dysautonomia is the condition where NESA is closest to its own definition: the device is neuromodulation of the autonomic nervous system. It works on the regulation itself — not on a single symptom.
We force nothing. We speak the language the body already uses.
NESA XSIGNAL® is a certified medical device for non-invasive neuromodulation of the autonomic nervous system.
Your body runs on electricity
The autonomic nervous system — the one that governs sleep, alertness, bladder and digestion — works at very low frequencies: between 1 and 14 cycles per second.
NESA speaks in the same window
Microcurrents in that same frequency range, delivered through gloves and ankle cuffs while you lie down or sit in a chair. No needles, no medication, no preparation.
The fact that you cannot feel it is why it works
The signal sits below the threshold of sensation. Because it does not trigger the body’s defences, the nervous system does not habituate to it, and the signal can accompany it session after session.
The practitioner’s hands stay free
The session runs alongside another therapy — physiotherapy, conversation, rehabilitation. Not a separate appointment, but a layer over the treatment already under way.
Manufacturer data, NESA (NGS Health and Mind S.L.), post-market surveillance system, as of July 2026. The zero refers to reported serious adverse events, not to the absence of any reaction whatsoever.
When would I notice anything?
It depends on one thing: how long the regulation has been disturbed. We say so up front, so you know what to expect — and so you do not stop after the third session because nothing has happened yet.
The first changes are usually felt here — most often in sleep and in recovery.
The more substantial change comes in this range, at a steady rhythm of two sessions a week.
With a chronic profile the work is done in blocks. After each block, a fresh assessment with objective measures, not by feel alone.
A guiding framework from practice, not a promise of results. The exact schedule is set by the practitioner delivering the treatment.
The figures come from the manufacturer — with the source.
NESA is used in clinics and hospitals across 53 countries and is the subject of more than 20 peer-reviewed publications. The manufacturer publishes the results together with the journal and PMID of each study — so anyone can check the source themselves instead of relying on a retelling.
Where this leads.
A complaint rarely belongs to one specialty alone. This is where one usually starts with it — and what each page covers.
Short answers, no hedging.
Is dysautonomia curable?
That depends on the cause and the form. Some cases respond well, others are managed long term. NESA is not a treatment for dysautonomia — it supports the regulation the condition rests on.
Do I need a diagnosis first?
At least a clarified picture. Orthostatic symptoms and palpitations have other causes too, which are treated differently.
And in POTS?
Practice uses it, but the judgement rests with the treating practitioner. It starts with an assessment at the centre, not with a treatment.
Are there side effects?
The manufacturer records zero reported serious adverse events across more than six million treatments delivered, as of July 2026. That does not replace the practitioner’s judgement for your case.
It rarely comes alone.
Complaints of the autonomic nervous system rarely arrive on their own. If you recognise another one here, that is most likely not a coincidence.
Where can I get a NESA session?
