POTS Lives at the Intersection of Blood Flow and Nervous System
Postural orthostatic tachycardia syndrome - POTS - is often described purely in cardiovascular terms: stand up, heart races, feel awful. That is accurate but incomplete. POTS lives at the intersection of blood flow and nervous system regulation, and the most effective self-management approaches work on both.
The core problem is that on standing, the autonomic nervous system fails to properly regulate blood flow against gravity, and the heart compensates by racing. But the autonomic dysregulation behind this is broader than the heart rate alone, which is why a purely cardiac lens misses much of what can actually be managed. A neuro-vagal approach widens the view to the nervous system that is failing to regulate in the first place.
The Autonomic Picture
POTS is fundamentally a disorder of autonomic regulation. The autonomic nervous system, which is supposed to automatically adjust blood vessel tone and heart rate to keep blood flowing to the brain when you stand, is not doing its job smoothly.
This is why POTS so often travels with other signs of autonomic dysregulation - fatigue, brain fog, temperature dysregulation, digestive issues, exercise intolerance - and why it overlaps so heavily with long COVID and ME/CFS. It is also why heart rate alone is a poor guide to POTS management: it captures one output of a much broader regulatory problem. Understanding POTS as autonomic, not merely cardiac, changes what you track and what you do.
The Vagal Lever
The vagus nerve, the main highway of the parasympathetic nervous system, is central to autonomic regulation - and it offers one of the few accessible levers in POTS.
Supporting vagal function and autonomic stability is a recognised part of POTS self-management. Practices that engage the parasympathetic system - slow, extended-exhale breathing in particular - can help shift the autonomic balance and are a core tool. Alongside the well-established foundations of hydration, sodium, compression and carefully graded (often recumbent) exercise, working the vagal lever addresses the regulatory system itself rather than only its cardiac symptom. It is not a cure, but it is a genuine point of influence.
Tracking the Right Variables
Because POTS is a whole-system autonomic problem, managing it well means tracking more than heart rate: orthostatic response, hydration and sodium, sleep, activity and post-exertional symptoms, menstrual phase, and how you respond to the interventions you try.
This is exactly what Recalibrate's POTS tracking is built for - capturing the full set of variables that actually drive POTS day to day, combining them into a Stability Score, and helping you see what stabilises your system and what provokes it. POTS management lives at the intersection of blood flow and nervous system regulation - so the tools should work at that intersection too. The free POTS and dysautonomia portal is a strong starting point.
Recalibrate is an education and self-tracking tool, not a diagnostic service or a replacement for medical care.
