Neurological Recovery & Dysautonomia
When Your Nervous System Doesn't Feel Like Your Own
If dizziness, brain fog, fatigue, exercise intolerance or other neurological and autonomic symptoms are affecting everyday life, explore whether Hyperbaric Oxygen Therapy could form part of your wider approach to recovery and wellbeing — with personal guidance from ReWell, in our Kildare or Dublin clinic or from your own home.
Does This Sound Familiar?
When Everyday Life Starts Feeling Unpredictable
Neurological and autonomic symptoms can affect people in very different ways. Dizziness, changes in heart rate, fatigue, brain fog and difficulty standing or exercising can make even ordinary daily activities difficult.
The Science
How HBOT May Support Neurological Recovery
The brain and nervous system have exceptionally high energy demands and rely on a continuous supply of oxygen. Following neurological injury or disruption, changes can occur in brain metabolism, blood flow, inflammation and cellular function.
Hyperbaric Oxygen Therapy increases the amount of oxygen dissolved in the blood plasma. Under pressure, this temporarily increases oxygen availability throughout the body, including to brain tissue. Researchers are studying how this may influence processes involved in neurological function, repair and adaptation.
Supports Oxygen Availability
HBOT significantly increases dissolved oxygen in the blood plasma, temporarily increasing the oxygen available to tissues during treatment.
May Support Brain Metabolism
The brain requires significant amounts of oxygen for normal cellular activity. Increased oxygen availability is one area being investigated in neurological recovery research.
Neuroplasticity Research
Researchers have investigated whether hyperbaric conditions may influence biological processes associated with neuroplasticity — the brain's ability to adapt and reorganise.
Inflammatory Pathways
HBOT has also been studied for its effects on inflammatory and oxidative pathways in a number of neurological research settings.
The Research
What Does the Research Say?
Hyperbaric Oxygen Therapy has been studied across several areas of neurological recovery, including traumatic brain injury and cognitive function. Some studies have reported improvements in selected neurological or cognitive outcomes, while findings across the wider evidence base remain mixed.
Neurological Recovery Research
HBOT has been investigated in people experiencing neurological and neurocognitive impairment, with researchers examining outcomes including memory, attention, cognition, executive function and processing speed.
Evidence varies according to the neurological condition, study design, treatment protocol and outcomes being measured.
Cognitive Function
Research following traumatic brain injury has included randomised controlled trials and observational studies. Some have reported changes in selected cognitive and functional outcomes.
Results have not been consistent across all studies, and larger controlled trials using standardised protocols remain important.
A Developing Evidence Base
Neurological HBOT research continues to explore oxygen availability, brain metabolism, inflammation and neuroplasticity as potential mechanisms relevant to recovery.
Results from one neurological condition cannot automatically be generalised to another, particularly where dysautonomia is concerned.
What does this mean for neurological recovery? Research into HBOT and neurological recovery is ongoing, with some encouraging findings alongside important limitations and mixed results. Evidence specifically for dysautonomia remains limited, so HBOT should not be presented as a proven treatment for autonomic dysfunction.
Your Guide
Neurological Recovery Is Complex. Your HBOT Approach Should Be Personal.
When someone comes to ReWell with neurological or autonomic symptoms, Davitt starts by understanding the person rather than simply the condition — what you're experiencing, how it affects everyday life, your health history, any diagnosis or care you're already receiving and what you're hoping to support.
Davitt Meenaghan is the Founder and Director of ReWell and an IBUM-certified Hyperbaric Safety Officer. His wider work is focused on functional medicine, biohacking, longevity and understanding the conditions that allow people to flourish. At ReWell, that means HBOT isn't viewed as a stand-alone answer, but as one potential tool within the wider picture of health and recovery.
For people exploring HBOT in the context of neurological recovery, Davitt helps make sense of what increased oxygen availability may mean, what areas such as brain metabolism, inflammation, cognitive function and neuroplasticity are being investigated, and — just as importantly — where the current evidence has limitations.
Because symptoms such as dizziness, brain fog, fatigue, exercise intolerance and changes in heart rate can arise for many different reasons, Davitt does not assume that the same approach will suit everyone. If HBOT is appropriate for you to explore, he can guide the practical side of your experience and help you consider how it may fit alongside your existing care and wider approach to health.
Bioindividual, not one-size-fits-all.
There is no single established HBOT programme for neurological recovery or dysautonomia that can be assumed to suit everyone. Your underlying condition, symptoms, health history, current level of function, medical circumstances and intended use all matter. ReWell's role is to help you explore HBOT responsibly as a potential adjunct — not to replace appropriate neurological or medical assessment, diagnosis or treatment.

The Process
How Your ReWell Experience Works
From your first conversation onwards, the aim is to help you understand your options and choose an approach that makes sense for your circumstances.
Discovery Call
Tell us about your symptoms, health history, any diagnosis or existing care and what you're hoping to achieve. Davitt will talk you through whether HBOT may have a place within your wider approach and which access option may be most appropriate.
Individual Guidance
Your circumstances, goals, intended use and wider health picture are considered rather than applying exactly the same approach to every person.
Clinic Visit or Home Delivery
Book a clinic session in Kildare or Dublin or, if you're renting a chamber, ReWell will arrange nationwide delivery, installation and a full practical walkthrough.
Ongoing Support
Support doesn't end once your session or rental begins. The ReWell team remains available for practical questions, guidance and ongoing support throughout your experience.
Why ReWell
A More Considered Approach to HBOT
ReWell's approach reflects a wider belief that health is individual and that technology should support the foundations of wellbeing rather than replace them.
Personally Guided
Led by Davitt Meenaghan, an IBUM-certified Hyperbaric Safety Officer. ReWell considers your circumstances, goals and intended use rather than treating HBOT as one-size-fits-all.
Nationwide Access
Access HBOT through clinic sessions in Kildare or Dublin, home chamber rental across all 32 counties or long-term chamber ownership.
Support Beyond the Chamber
ReWell sees HBOT as one tool within a much wider picture of health. Education, practical guidance and ongoing support remain part of the experience.
Common Questions
Frequently Asked Questions
Is HBOT proven to treat dysautonomia?
HBOT is not currently an established treatment for dysautonomia itself, and research specifically examining HBOT for autonomic disorders remains limited. HBOT is being researched across several areas of neurological health and recovery, but findings from other neurological conditions cannot automatically be applied to dysautonomia.
How is HBOT being studied in neurological recovery?
HBOT increases the amount of oxygen dissolved in the blood plasma. Researchers are investigating how increased oxygen availability may influence processes including brain metabolism, inflammation and neuroplasticity in certain neurological conditions. Evidence varies considerably according to the condition being studied.
Can HBOT help with brain fog, dizziness or fatigue?
Brain fog, dizziness and fatigue can have many different causes, including autonomic, neurological and other medical conditions. Some neurological HBOT research has reported changes in certain cognitive outcomes, but there isn't sufficient evidence to promise that HBOT will relieve these symptoms in people with dysautonomia. Appropriate investigation of the underlying cause remains important.
How many HBOT sessions are needed for neurological recovery?
There is no universally established HBOT programme for neurological recovery or dysautonomia. Research programmes vary considerably, and frequency and duration depend on the condition, individual circumstances and intended use. ReWell therefore guides the experience around the individual rather than promising results within a set number of sessions.
Is HBOT suitable for everyone?
No. HBOT is not suitable for everyone and some medical conditions require particular consideration. Your health history, symptoms and current care should be considered before starting. HBOT should complement — not replace — appropriate medical assessment or treatment.
Where can I access HBOT in Ireland?
ReWell offers guided HBOT sessions at our clinics in Naas, Co. Kildare and Dublin, as well as home chamber rental with delivery and installation across all 32 counties.
