The first six months were managed through sheer determination. The infection had been mild — three days of fatigue, a fortnight of slightly diminished smell, what felt like a comfortable recovery. The return to work happened on schedule. The half-marathon training resumed. The household ran as it had always run. And then, somewhere around month three, the body began to do things it had never done before. The afternoon energy crash that did not lift by morning. The brain fog that turned the simple email into a forty-minute task. The standing dizziness on the school run that arrived without warning. The heart rate that rose unaccountably while sitting still.
By month six, the trajectory was undeniable. By month twelve, the diagnosis had been arrived at, often after a series of tests that ruled out everything except the condition that the language of the health system had not yet quite settled into a tidy name for. Long COVID, post-COVID syndrome, post-acute sequelae of COVID-19, post-viral fatigue syndrome — the labels varied. The lived experience was unmistakable.
For many in this category, the additional recognition arrives later — that what they have looks, structurally, very much like ME/CFS as it was known before the pandemic, and that ME/CFS itself has been a condition the health system has struggled with for decades. This piece is for both groups, and for those whose post-viral picture extends to other infections beyond COVID. It is about why the standard pathways have been failing this population, and about what an autonomic-focused approach can add.
What These Conditions Actually Are, Functionally
The clinical definitions remain contested, and the research is in active development. What is increasingly clear, across the various names and frameworks, is that the conditions share a substrate — sustained dysregulation of the autonomic nervous system, with the parasympathetic branch unable to recover its normal regulatory function, the sympathetic branch in chronic low-grade activation, and the body’s energy production, immune regulation, and post-exertional recovery all operating on a budget that has been substantially reduced.
The most useful clinical framework for this presentation, in our experience, draws on the polyvagal model developed by Stephen Porges. The model proposes three principal autonomic states — the ventral vagal state of social engagement and rest, the sympathetic state of mobilisation, and the dorsal vagal state of shutdown. In healthy regulation, the system moves fluidly between these states as conditions require. In long COVID and ME/CFS presentations, the system has often lost its capacity for fluid movement. It is stuck, in varying mixtures, between sympathetic activation and dorsal vagal shutdown, with the ventral vagal state of genuine rest and connection largely unavailable.
This is not a metaphor. It is a description of what physiological measurement reveals when this population is assessed carefully — altered heart rate variability, abnormal orthostatic responses, abnormal baroreflex sensitivity, abnormal cardiac vagal tone. The autonomic dysfunction is real, measurable, and substantially explains the symptom cluster these patients describe.
Why the Standard Pathways Have Struggled
The treatment models that the health system has reached for in this population have, until recently, fallen into two categories. The first is graded exercise therapy and cognitive behavioural therapy, which were the recommended approaches for ME/CFS for many years and were rolled forward into long COVID care in many settings. The second is symptom management — pacing advice, medications for specific symptoms, supportive primary care.
The first category has been increasingly recognised as harmful for a meaningful subset of patients. Graded exercise, in particular, can produce post-exertional malaise that worsens the underlying dysautonomia rather than improving it. The cognitive behavioural element, while useful for some adjacent issues, does not address the autonomic substrate and, when offered as the primary intervention, frequently produces the felt experience of being told that the condition is essentially psychological — which it is not.
The second category is broadly competent at managing what it manages, but it is not designed to produce recovery. It is designed to make the present sustainable. For patients with a long arc of illness ahead of them, the absence of any recovery-oriented framework is a significant gap.
What has been largely missing from the standard pathways is the autonomic regulation work that this population actually needs.
What Polyvagal-Informed Recovery Work Involves
The clinical approach that addresses the autonomic substrate directly has several features. It starts from a careful baseline assessment of where the patient’s autonomic regulation actually sits, including heart rate variability where available, orthostatic measurement, and a careful history of post-exertional patterns. It then introduces interventions calibrated to the patient’s current capacity rather than a generic protocol.
The interventions themselves are intentionally low-intensity. This population cannot tolerate high-intensity work, and pushing them to do so is one of the most common errors in care. What we use, in graded and individualised combinations: vagal toning practices including specific breathwork patterns, slow movement adapted to current capacity, cold exposure carefully introduced, light therapy aligned with circadian rhythm, gentle somatic experiencing work, biofeedback to retrain autonomic flexibility, and where appropriate, supportive use of hyperbaric oxygen therapy at protocols calibrated for this population.
What we explicitly avoid: aggressive exercise prescriptions, generic stress-management approaches, intensive psychological work that the autonomic state cannot tolerate, and any framing that suggests the condition is fundamentally psychological in origin. The work is physiological. The psychological accompaniment is supportive of the physiological work rather than a substitute for it.
What Recovery Actually Looks Like in This Population
Recovery in long COVID and ME/CFS is rarely linear and rarely complete in the way patients initially hope. It is, often, the slow re-establishment of autonomic flexibility, with the patient’s window of tolerance for activity widening over months, the post-exertional malaise becoming less severe, the cognitive function clearing in fits and starts, and the sense of trapped-ness beginning to lift before the symptoms themselves fully resolve.
For some patients, this trajectory produces functional return — the half-marathon does not happen again, perhaps, but the working life, the family life, and the social life become sustainable in a way they had not been. For others, the trajectory is more modest, but the trajectory itself — the felt sense of moving toward rather than treading water — is itself a substantial change from the pattern that came before.
The setting that produces this work most efficiently is residential, in our experience. The autonomic regulation work requires consistency, the avoidance of post-exertional triggers, careful clinical attention to pacing, and a held container that the home environment, with its work demands and family demands, almost never provides. Three to four weeks is the minimum window in which meaningful retraining of autonomic patterns can occur, with longer windows often appropriate for patients whose illness has been prolonged.
A Note for People Currently Pacing Through Each Day
If you have arrived here after months or years of being told that what you have is not entirely real, or that the recovery should have happened by now, the work that addresses your actual condition does exist. It is not yet widely available through standard medical pathways, and it is not what generic wellness programmes offer. It is specifically calibrated to the autonomic substrate that your symptoms are arising from, and it is something that, in increasing numbers, this population is finding meaningful relief through.
The inquiry can begin whenever the energy allows. It does not have to begin with a commitment. It only has to begin with a conversation in which what you have been carrying gets to be received by someone who recognises it.
