The cardiology appointment usually ends the same way.
The heart is structurally fine. The echo is clean, the rhythm is normal, nothing needs fixing. Which is genuinely good news, and also completely at odds with the fact that standing up makes the room tilt, that a shower leaves you needing to sit down, and that you have learned to plan your day around how long you can stay upright.
Both things are true. Your heart is fine. Your system is not. Managing POTS symptoms starts with understanding why those two statements do not contradict each other.
What POTS Actually Is
Postural orthostatic tachycardia syndrome describes a specific pattern: on standing, the heart rate rises sharply and stays elevated, without the drop in blood pressure that would explain it.
The tachycardia is not the problem. It is the compensation. When you stand, gravity pulls blood downward, and a well-regulated system responds instantly — vessels constrict, return improves, and you barely notice. In POTS that response is inadequate, so blood pools in the lower body and the heart compensates by beating faster to maintain flow to the brain.
That explains the symptom list, which otherwise looks scattered: lightheadedness, palpitations, brain fog, fatigue, nausea, shakiness, sometimes fainting. They are all downstream of the same problem — a regulatory system that is not adjusting properly to a change in position.
It is a condition of the autonomic nervous system, which is exactly why the cardiac workup comes back clean. Cardiology was asking whether the pump is damaged. The pump is fine. The regulation is not.
Why the Two Sides of Your Nervous System Matter Here
The autonomic nervous system runs on two branches that balance each other.
The sympathetic branch handles activation — heart rate, alertness, readiness. The parasympathetic branch handles rest, digestion and repair. In POTS and the broader family of dysautonomias, that balance is disrupted, and the system tends to sit heavily on the activated side.
Which is why the symptom picture extends well past standing up. Digestion becomes unreliable, sleep stops restoring, temperature regulation goes off, and the whole system loses tolerance for small changes — a warm room, a missed meal, a poor night, a minor infection. Things that would not register for someone else become significant events.
That intolerance is not fragility on your part. It is what happens when a regulatory system is already working at the edge of its capacity to keep you upright.
What the Evidence Supports First
Before anything else, the well-established foundations. These are not alternatives to medical care — they are the first-line non-pharmacological approach in mainstream POTS management, and they are frequently underused.
Fluid volume. Around 2 to 3 litres a day for most adults, spread through the day rather than taken all at once. Low blood volume is central to the problem, and hydration is the most direct lever on it.
Sodium — with your physician’s approval. Increased dietary salt helps retain the fluid you are drinking and expand plasma volume, and it is standard in POTS protocols. It is also not appropriate for everyone, including people with kidney disease, high blood pressure or in pregnancy, so the amount is a conversation to have with your doctor rather than a number to copy from an article.
Compression. Garments that reach the waist, or an abdominal binder, work better than knee-high socks. Most venous pooling happens in the abdomen and pelvis, so compression that stops at the calf is addressing the wrong area.
Exercise, in the right order. This one is counterintuitive and it matters more than any other item here. Exercise is now considered first-line non-pharmacological treatment for POTS, but the starting position is the key detail. Programmes begin with horizontal or semi-recumbent work — rowing, swimming, recumbent cycling — so that conditioning happens without triggering the upright response. Duration and intensity build gradually, and upright exercise is added only as tolerance allows.
Practical adjustments. Sleeping with the head of the bed raised, counter-pressure manoeuvres such as crossing the legs or clenching the calves before standing, smaller and more frequent meals, and rising in stages rather than all at once.
These are unglamorous, and they are also where most of the reliable gains come from. Anyone offering something more exciting before these are in place has the order wrong.
Why Progress Often Stalls Between Appointments
Most people with POTS leave appointments with a reasonable plan and then hit the same wall: the plan describes what to do, not how to build the capacity to do it.
Being told to exercise when standing up is the problem is a real barrier. So is being told to hydrate when nausea makes drinking difficult, or to sleep better when the autonomic state that causes the symptoms is also disrupting sleep. Each recommendation assumes a baseline of capacity that the condition itself is taking away.
That circular problem is where a nervous system approach is genuinely useful — not as an alternative to the foundations above, but as a way to build enough capacity for them to become possible.
What an Evaluation Involves
A full history. POTS frequently follows an identifiable event — a viral illness, a period of prolonged bed rest, surgery, physical trauma, or a stretch of sustained stress. Establishing that timeline matters, and so does everything before it, because it tells us what your system was carrying beforehand.
A detailed neurological examination. We assess function across the 88 major nerves branching from the brain and spinal cord — what we call EnergyFlow — mapping where signal is running below capacity. It is closer to walking a breaker box than to asking whether the building has power, and it addresses the layer no cardiac test is designed to describe.
Daily inputs. Sleep, hydration, breathing pattern, meal timing, heat exposure, activity and total stress load.
The output is a picture of current autonomic and functional capacity, and a plan paced to it — shared with the physician managing your care, not kept separate from them.
Foundations and Technology
Breathing is the most immediately useful tool available in dysautonomia, and the most underused. A slow exhale that is longer than the inhale directly engages the parasympathetic branch — it is one of the few levers that reaches the autonomic system voluntarily. Five minutes, several times a day, done lying down at first.
Alongside that, and the OWL foundations of Oxygen, Water and Light, plans at the Lafayette clinic draw from:
- BRT Bioresonance — frequency-based nervous system support
- PEMF & Grounding — pulsed electromagnetic field support
- Theralight360 — full-body red light and photobiomodulation
- HBOT — hyperbaric oxygen therapy
- Quantum Neurology — targeted nerve function work
Pace is set deliberately low at the start. People with POTS commonly react badly to intensive protocols, and the reason is not sensitivity — it is that a system already at the edge of its capacity reads heavy input as another demand. Build tolerance first, then load.

[ Embed YouTube interview here — add URL ]
In this conversation, Dr. Chris Cormier, DC discusses how he approaches autonomic regulation in people with POTS, why the full history comes before any examination, and what he looks for when cardiac testing has come back clear.
Individual results vary. Cases discussed reflect clinical experience and are not a prediction of outcome for any other person.
What This Approach Is — and What It Is Not
POTS needs a proper diagnosis first. Orthostatic tachycardia can also be caused by conditions that need different treatment entirely — thyroid disorders, anaemia, adrenal problems, arrhythmias and medication effects among them. If you have not been formally assessed, that comes before anything on this page.
Fainting always warrants medical assessment. If you are losing consciousness, that needs a physician’s evaluation, not a wellness plan. Say so clearly to whoever is treating you, and do not let it be normalised.
Some people with POTS need medication, and that is a legitimate part of care. Several are used effectively for this condition. Whether you need one, and which, belongs with your physician — not with us, and not with anything you read online.
What this work adds is the regulatory layer: autonomic balance, functional capacity and the daily foundations that determine whether the standard recommendations are even achievable. For many people that is the missing piece between having a plan and being able to follow it.
Tracking Your Own Pattern
POTS varies day to day, and the variation is informative. A daily line covering:
- Standing tolerance — how long, before symptoms start
- Resting and standing heart rate if you track it
- Fluid and sodium intake
- Sleep quality and hours
- Heat exposure and how you responded
- Activity, and what it cost you the following day
- Any near-fainting episodes and what preceded them
Within a couple of months this gives you two valuable things: your own trigger pattern, and your current threshold — the level of activity you can sustain without paying for it the next day. Both change over time, and both are far more useful than a general sense of good days and bad days.
Continuing at Home
BodyChargers by Dr. Chris covers the at-home side — breathing protocols, nervous system regulation, sleep, hydration and the OWL foundations, with programmes organised by topic. For a condition where travelling to an appointment can itself cost a day, that consistency between visits carries a lot of the weight.
Key Takeaways
Normal cardiac tests and severe symptoms are not a contradiction in POTS. The tests were asking about the pump. The problem is with regulation.
The best-supported first steps are also the least exciting ones — fluid, sodium where appropriate, waist-high compression, and exercise started in a horizontal position and built gradually. Get those in place before anything else, and expect the gains to be real.
Where the barrier is not knowing what to do but having the capacity to do it, the autonomic layer is worth addressing directly. That is the piece most people have never had assessed.

Frequently Asked Questions
Why is my heart rate high if my heart is healthy?
Because the raised heart rate is a response, not a fault. When blood pools in the lower body on standing, the heart speeds up to maintain flow to the brain. Cardiac testing checks whether the heart itself is damaged, and in POTS it usually is not. The problem sits in the autonomic system that regulates blood vessels and volume.
Is POTS the same as dysautonomia?
POTS is one form of dysautonomia, which is the broader term for disordered autonomic function. Many people with POTS have symptoms extending beyond orthostatic intolerance — digestion, temperature regulation, sleep — which reflects that wider autonomic involvement.
Should I really be exercising if standing makes me ill?
Yes, but the starting position matters enormously. Exercise is considered first-line non-pharmacological treatment for POTS, and programmes begin horizontally or semi-recumbent — rowing, swimming, recumbent cycling — so you can build conditioning without provoking the upright response. Upright work is added later as tolerance allows. Starting with standing exercise is how people conclude that exercise makes POTS worse.
How much salt should I be having?
That is a question for your physician rather than an article. Increased sodium is standard in POTS management because it helps retain fluid and expand blood volume, but it is not appropriate for everyone — kidney disease, hypertension and pregnancy all change the calculation. Get a specific figure from the doctor who knows your case.
Why does heat affect me so much?
Heat causes blood vessels to dilate, which worsens pooling and makes the regulatory problem harder. This is why hot showers, warm weather and even a hot meal can trigger symptoms. Cooling in advance of activity rather than afterwards, and timing demanding tasks for cooler parts of the day, both help.
Will POTS ever get better?
Many people improve substantially, particularly with consistent management, and some — especially where onset followed a viral illness — see symptoms resolve over time. Others manage it longer term. We are not going to promise you an outcome, but the picture is more hopeful than the point of diagnosis usually feels.
