Altitude and intermittent-hypoxia therapy

1. Introduction

Version followed: the method as described in the Soviet/Russian normobaric hypoxytherapy literature and its official Russian methodological recommendations (Razsolov, Chizhov, Potievsky & Potievskaya, Normobaric hypoxytherapy, methodological recommendations for aviation physicians, Moscow 2002), together with the contemporary international research literature on intermittent hypoxia conditioning and intermittent hypoxia–hyperoxia training (IHT / IHHT), and with alpine altitude climate treatment as published by respiratory medicine. No single founder's manual governs this field, and no protocol parameters are reproduced here. [source: medi.ru/info/2712 and sub-pages; Zhang et al. 2023; Rybnikova et al. 2022; Fieten 2022]

This is not a psychotherapy. It is a family of physiological interventions in which a person is exposed, repeatedly and briefly, to air containing less oxygen than usual — by travelling to or living at altitude, by sitting in a low-pressure or low-oxygen chamber, or, in the modern form, by breathing a reduced-oxygen gas mixture from a device called a hypoxicator, alternating with ordinary or oxygen-enriched air. The stated idea of change is adaptive stress, or hormesis: a stimulus too small to injure is said to provoke the body's own protective machinery — ventilatory and cardiovascular regulation, erythropoiesis, antioxidant enzymes, mitochondrial and vascular adaptation — so that the person afterwards copes better with other stressors, a process the Russian literature calls cross-adaptation. [source: Zhang et al. 2023; Rybnikova et al. 2022]

The tradition has three strands that a therapist will meet under the same words. (i) Altitude cures and altitude climate therapy — the oldest, a stay at a mountain clinic, which survives today mainly as alpine altitude climate treatment for severe uncontrolled asthma delivered by specialist clinics in Switzerland, Italy, France and Germany. [source: Fieten 2022] (ii) Soviet and Russian hypoxic training — from the 1930s, Soviet researchers used repeated stays in high-mountain camps, repeated high-altitude flights, altitude chambers, and later the breathing of low-oxygen mixtures; in the 1980s the normobaric form was developed so that mountain exposure could be imitated at sea level. Chizhov and Strelkov are credited with the concept, Meerson with the adaptation and cross-adaptation theory behind it; R. B. Strelkov holds 1992 Russian patents for a hypoxicator apparatus, and the "Mountain Air" (Gorny vozdukh) method is described in a 1994 monograph. Serebrovskaya's 2002 review in High Altitude Medicine & Biology is the standard English-language account of this history. [source: Serebrovskaya 2002; medi.ru/info/2712; Rybnikova et al. 2022] (iii) Commercial IHHT — clinic and home devices sold for cardiac rehabilitation, "healthy ageing", cognition, stress and sleep. [source: Ai Mediq company materials]

A psychotherapist does not deliver any of this. What a psychotherapist does is recognise what a client is already doing or being sold, screen for the situations in which it is dangerous, route the medical questions to a physician, and work psychologically with the expectations, the disappointment, the avoidance or the altitude-related mood change that come with it. That is what sections 4 and 5 set out. [synthesis]

2. Framework

There is no agreed protocol. Reviews state plainly that no universally accepted protocol exists and that studies differ widely in method. [source: Zhang et al. 2023] What follows is the shape of a course as providers and official recommendations describe it — deliberately without hypoxia levels, oxygen percentages, session lengths, session counts or device settings, none of which belong in a psychotherapist's guide and none of which a psychotherapist should set.

Stage A — medical selection. A physician takes a history and examines for the contraindications listed in section 4. The Russian methodological recommendations require an individual hypoxic test before every course, specifically to detect individual intolerance of oxygen deficiency, which is itself listed as a contraindication; marked pallor, heavy sweating, and steep rises in pulse, blood pressure and respiratory rate appearing very early in the test mean the method is contraindicated for that person. Transient slowing of the pulse that settles on ordinary air is not treated as a contraindication but is noted as a possible signal of sinus node disease. [source: medi.ru/info/10574] Research protocols exclude, among others, unstable angina, severe heart failure, arrhythmia, untreated hypertension, uncontrolled diabetes, significant lung disease, cancer, acute inflammatory illness, dependence on supplemental oxygen, and low resting oxygen saturation. [source: Behrendt et al. 2022]

Stage B — the course. Repeated sessions, usually several a week over some weeks, under monitoring. Modern clinic devices continuously read pulse and oxygen saturation and adjust the exposure to the individual's response; Ai Mediq markets this as "self-regulated treatment". [source: Ai Mediq company materials] In research settings the sessions are often given before or alongside exercise or rehabilitation training rather than alone. [source: Behrendt et al. 2022; Bayer et al. 2019]

Stage C — review and maintenance. Outcomes are judged on whatever the indication was (exercise tolerance, symptom scores, cognitive screening measures), and courses are repeated at intervals. Evidence for maintenance is not established. [uncertain]

Altitude climate treatment runs on a different frame: referral of patients whose asthma stays uncontrolled on maximal guideline treatment, an inpatient or residential stay at a specialist alpine clinic, and a personalised multidisciplinary rehabilitation programme that includes self-management education, treatment of modifiable risk factors and comorbidities, and psychological assessment and treatment of stress-related factors — the point at which a psychologist is formally part of the team. Reported treatment durations vary widely across studies. [source: Fieten 2022]

Criteria for moving between stages are medical, not psychological: clearance at Stage A, tolerance of each session at Stage B, and a physician's judgement at Stage C. A psychotherapist's only gatekeeping role is to decline to encourage a client who has not been medically screened, and to pass on symptoms that arise. [synthesis]

Who delivers it. Physicians (cardiology, rehabilitation, respiratory, sports and aviation medicine), supervised by them nurses, physiologists and physiotherapists, in hospitals, rehabilitation units, sports institutes and spa-type facilities; altitude climate treatment by specialist respiratory clinics with multidisciplinary teams; and, increasingly, commercial wellness, longevity and "biohacking" clinics with no medical supervision stated. [source: Fieten 2022; Ai Mediq company materials] [synthesis for the last]

Regulation, as sources state it. The ReOxy device carries a CE mark obtained in 2016 as a medical device and, per the manufacturer, TÜV Rheinland approval for professional use in healthcare facilities treating cardiac patients; the stated indication is improving tolerance to physical load in coronary artery disease within cardiac rehabilitation. The company's own 2019 material states no device class and no ISO standard, and its 2025 launch release describes a separate home device with no regulatory status given, no contraindications and no advice to consult a clinician. [source: Ai Mediq company materials; Ai Mediq press release 2025] No FDA clearance is mentioned in those materials. [uncertain: regulatory status outside the EU not verified] Regulatory clearance of a device is a statement about the device, not evidence that a claimed benefit exists — worth saying to clients in those words. [synthesis]

3. Guiding principles

You are not the prescriber. Every question about whether this is safe for this person goes to a physician who knows their heart, lungs and medication. [source: medi.ru/info/10574]
Dose and pattern decide whether hypoxia helps or harms. The same intermittent hypoxia that is marketed as therapy is, in a severer and nightlier pattern, the mechanism by which obstructive sleep apnoea damages the cardiovascular, metabolic and cognitive systems. [source: Mateika research programme summary; Zhang et al. 2023]
Say which strand you mean. "Altitude therapy" may mean a Davos asthma admission, a Russian hypoxytherapy course, an athlete's camp or a longevity-clinic session; the risks and the evidence differ. [synthesis]
Evidence status before enthusiasm. Most of this literature is preclinical, small, uncontrolled or industry-adjacent; reviews themselves call for large randomised trials. [source: Zhang et al. 2023; Rybnikova et al. 2022]
Never present it as a treatment for a disease. Not for cancer, dementia, depression or anything else. Describe what is claimed, by whom, with what support. [synthesis]
Mood at altitude cuts both ways. Residential altitude is associated in epidemiological work with higher rates of depression and suicide; a client who feels worse after moving uphill is not imagining it, and the association is not proof of cause. [source: Kious, Kondo & Renshaw 2018]
Watch the hormesis story being used to justify harm. "Stress makes you stronger" is used to sell breath-holding and improvised oxygen deprivation that kills people. [source: Red Cross/USA Swimming/Y-USA 2022]
Screen for eating-disorder and over-exercise patterns before encouraging anything training-flavoured. Hypoxic training sits close to performance culture. [synthesis]
Keep the psychological formulation primary. If a client's depression, panic or insomnia is the target, offer the treatments that have evidence for those conditions and treat hypoxia work as an adjunct the client has chosen, not as your plan. [synthesis]
Document what you said. Where a client intends a physiologically risky activity, record the advice to seek medical clearance. [synthesis]
Respect the client's autonomy. Adults may choose unproven interventions; your job is accurate information, screening and continued care, not refusal of the relationship. [synthesis]

4. Intervention inventory

These are the things a psychotherapist actually does. The physiological procedures themselves are described only to the level a therapist needs in order to discuss them; no exposure levels, oxygen concentrations, session lengths or device settings are given anywhere in this guide, and a psychotherapist should not supply them.

4.1 Establishing which strand of "altitude therapy" is in play

Purpose: The word covers a hospital asthma admission, a physician-run hypoxytherapy course, a longevity-clinic package, an athlete's camp, a planned trek and a device bought online. Risk, regulation and evidence differ in each case, and so does your role. Do this before anything else. [synthesis]
Steps: Ask what is being done or proposed, where, by whom, with what equipment, under whose supervision, and what the client hopes will change. Establish whether a doctor has assessed them for it and whether that doctor knows their full history. Find out who recommended it and what was claimed. Note whether any money is at stake, and whether a course has been pre-paid — pre-payment shapes how willing a client is to report trouble.
Example language (illustrative): "Before I say anything useful I need to picture it. Who runs the sessions, what do they put you in or on, and who checked whether it was safe for you?"
Watch for: Vagueness about supervision; a provider described as a coach, consultant or practitioner with no clinical qualification named; equipment bought secondhand or improvised; the client not knowing what the device does.

4.2 Physical-safety screening before you encourage anything

Purpose: To identify the people for whom hypoxic exposure or altitude is contraindicated or needs medical caution, and to stop yourself from endorsing something harmful. [source: medi.ru/info/10574; CDC Yellow Book, Hackett & Shlim]
Steps: Ask, in plain terms, about: heart disease of any kind, including angina, heart failure, previous heart attack or stroke, heart rhythm problems, congenital or valve conditions and pulmonary hypertension; high blood pressure and whether it is treated and controlled; lung disease including asthma, COPD and any need for oxygen; diagnosed or suspected sleep apnoea and snoring with daytime sleepiness; diabetes; anaemia; epilepsy; pregnancy or trying to conceive; current infection or fever; recent surgery; cancer treatment; and all medicines, including sedatives, opioids and alcohol use. Record the answers. Where any of these are present, do not encourage; route to the prescriber (4.3). The official Russian contraindication list for normobaric hypoxytherapy names acute infection and febrile illness, acute events such as myocardial infarction, stroke, hypertensive crisis, pneumothorax and status asthmaticus, pulmonary embolism, conditions needing intensive care, decompensated chronic disease, congenital heart and great-vessel anomalies, decompensated acquired heart disease, and individual intolerance of oxygen deficiency. [source: medi.ru/info/10574] Research protocols additionally exclude unstable angina, severe heart failure, arrhythmia, untreated hypertension, uncontrolled diabetes, significant lung disease and low resting oxygen saturation. [source: Behrendt et al. 2022]
Example language (illustrative): "This is a physical treatment with a physical screening list, and some of the items on it are things people forget to mention — can we go through them?"
Watch for: Clients who minimise cardiac history; undiagnosed sleep apnoea presenting to you as treatment-resistant depression or fatigue; pregnancy not yet disclosed; a provider who has asked none of this.

4.3 Routing the medical question and writing to the prescriber

Purpose: Medical clearance is not your decision, and a short letter changes what the doctor knows. [synthesis]
Steps: With consent, write to the GP, cardiologist, respiratory physician or psychiatrist. State what the client intends, what you have observed psychologically, the specific concern (for example suspected sleep apnoea, a cardiac history, pregnancy, or psychiatric medicines plus planned altitude travel) and what you are asking for. Ask that the answer come back in writing to the client. Do not offer an opinion on whether the exposure is medically safe, and never advise on medicines.
Example language (illustrative): "I'd like to write to your GP saying what you're planning and asking whether there's anything about your heart or your breathing that makes it a bad idea. I won't put anything in about our sessions beyond what you agree."
Watch for: Clients who say the clinic "already checked"; check what was checked. A refusal to involve the GP is itself information.

4.4 Setting out evidence status honestly

Purpose: Clients are being sold strong claims. Accurate framing prevents both false hope and reflexive dismissal, and protects the therapeutic relationship when results disappoint. [source: Zhang et al. 2023; Rybnikova et al. 2022]
Steps: Separate four things: what is established, what is promising but small, what is animal-only, and what is marketing. Current reviews describe intermittent hypoxia conditioning as a candidate strategy with findings across cardiac, metabolic, respiratory and neurological conditions, but state that much of the evidence is animal or small pilot work, that no accepted protocol exists, and that large randomised trials are needed. [source: Zhang et al. 2023] For cognition: a pilot study in mild cognitive impairment reported improvement, and one controlled trial in geriatric inpatients found a benefit on one cognitive test and none on another, with the authors calling the cognitive benefit uncertain. [source: Zhang et al. 2023; Behrendt et al. 2022] For mobility and perceived health in older people: a randomised trial found adding hypoxia–hyperoxia to a multimodal training programme produced no further gain. [source: Bayer et al. 2019] For depression: claims rest mainly on animal work; Russian official indications list neurotic, asthenic and depressive states, and Russian sources treat these as established indications, but that listing is not trial evidence. [source: Zhang et al. 2023; medi.ru/info/6963] [contested] For asthma via altitude climate treatment: many observational studies report improvement, but most lack control groups and randomised trials are called for. [source: Fieten 2022] For longevity, "cellular regeneration" and anti-ageing: marketing claims without cited trial support. [contested] [source: Ai Mediq press release 2025]
Example language (illustrative): "The honest position is: interesting, physiologically plausible, studied mostly in small groups, and oversold by the people who sell it. That doesn't mean don't — it means don't stop anything that's working for you in order to do it."
Watch for: A client who has stopped evidence-based treatment, or deferred psychiatric or medical care, to pursue this; that is the point at which you say so directly.

4.5 Describing what a session involves, so consent is real

Purpose: Clients often consent without knowing what will happen to their body or what will be monitored. [synthesis]
Steps: Describe, at the level of experience and not of settings: the person sits or reclines; a mask or hood delivers air with less oxygen than usual, alternating with ordinary or oxygen-enriched air; a finger probe and often an ECG or blood-pressure monitor run throughout; modern clinic devices adjust the exposure automatically in response to pulse and oxygen saturation. [source: Ai Mediq company materials; Zhang et al. 2023] Say that an initial test of individual tolerance is part of the standard Russian method and that intolerance disqualifies a person. [source: medi.ru/info/10574] Say that mild dizziness has been reported in trials. [source: Behrendt et al. 2022] Encourage the client to ask the provider what is monitored, who is in the room, how a session is stopped and what happens if they feel unwell.
Example language (illustrative): "Ask them three things: what are you monitoring, how do I stop it, and who in the building is medically qualified if I don't feel right?"
Watch for: A provider who cannot answer those questions; sessions with no monitoring; the client being left alone.

4.6 Preparing a client who is likely to panic in a mask

Purpose: Mask-based exposure produces breathlessness, lightheadedness and a sense of restriction — the exact interoceptive cues that trigger panic, claustrophobia and trauma responses. Preparation reduces aborted treatment and re-traumatisation. [synthesis]
Steps: Formulate the fear: is it suffocation, restriction, loss of control, medical settings, or being watched? Use your ordinary panic-management work beforehand: psychoeducation about the harmlessness of the sensations themselves in a monitored medical setting, a cognitive plan for catastrophic thoughts, and a rehearsed stop signal agreed with the provider. Agree a signal the client can use without speaking. Rehearse wearing a mask at home only if the provider supplies one for that purpose and the clinician agrees. Do not instruct the client in any breathing pattern for use during hypoxic exposure, and do not combine this with breath-holding or hyperventilation exercises of any kind. Make sure the client knows that feeling unwell is a reason to stop, not a failure.
Example language (illustrative): "Your body will give you signals that mean danger in ordinary life. In that room they are being measured by someone whose job is to stop the moment they matter. Your job is to say so, not to endure it."
Watch for: Clients with trauma histories involving suffocation, strangulation, drowning, intubation or restraint — discuss whether to proceed at all; dissociation during or after sessions; clients who override distress to please the provider.

4.7 Preparing a client for altitude travel

Purpose: Many clients meet hypoxia not in a clinic but on a trip. Altitude illness is largely preventable and deaths from it are generally preventable with gradual ascent and prompt descent. [source: CDC Yellow Book, Hackett & Shlim]
Steps: Tell them to get travel medical advice before going and to plan the ascent with a clinician. Teach recognition, not treatment: acute mountain sickness typically begins within hours of arriving higher, with headache plus some of appetite loss, dizziness, fatigue or nausea, and resembles a hangover; high-altitude cerebral edema is signalled by confusion, unsteady walking, drowsiness and altered mental state; high-altitude pulmonary edema by chest congestion, cough, unusual breathlessness on exertion and falling exercise capacity, progressing to breathlessness at rest. Teach the two rules the CDC states: never go higher to sleep while symptomatic, however mild; and descend if symptoms worsen despite rest — descent is the most effective treatment. Note that fitness does not protect, that prior altitude illness is the best predictor of recurrence, that children are as susceptible as adults, and that alcohol and opioids should not be used as sleep aids at altitude. [source: CDC Yellow Book, Hackett & Shlim] Where the client has a psychiatric history, see 4.8.
Example language (illustrative): "Two sentences to take with you: if you have symptoms you don't sleep any higher, and if they get worse you go down. Everything else is detail for the doctor."
Watch for: Goal-driven clients who will not turn back; group pressure on organised treks; clients who interpret early symptoms as weakness; a travelling companion who is unwell and being talked round.

4.8 Psychiatric stability, medicines and altitude

Purpose: Clients ask whether their mental health or medication makes altitude unsafe. You can frame the question and route it; you must not answer it pharmacologically. [synthesis]
Steps: Note that the CDC chapter lists stable psychiatric disorders as likely carrying no additional altitude risk, and warns against alcohol and opiates as sleep aids at altitude. [source: CDC Yellow Book, Hackett & Shlim] Direct all questions about specific psychiatric medicines, altitude and any altitude-illness prophylaxis to the prescriber. Plan for the practical destabilisers of travel rather than the pharmacology: sleep disruption, time zones, running out of medication, alcohol, isolation, and loss of routine. Build a relapse-warning plan with the client and, with consent, a named travelling companion.
Example language (illustrative): "I can't advise on your medication at altitude — that's your prescriber. What I can do is make sure the trip doesn't quietly dismantle your sleep and your routine."
Watch for: Clients stopping psychiatric medicines before a trip or a hypoxia course without telling the prescriber; stimulant or alcohol use to cope with altitude fatigue.

4.9 Sleep apnoea: recognising it and not confusing it with therapy

Purpose: Obstructive sleep apnoea is the clearest example of intermittent hypoxia doing harm, and it is routinely missed in psychotherapy clients presenting with fatigue, irritability, poor concentration and low mood. [source: Mateika research programme summary; CDC Yellow Book, Hackett & Shlim]
Steps: Ask about snoring, witnessed pauses in breathing, waking unrefreshed, morning headache and daytime sleepiness, and refer for assessment where suspected. Explain the distinction: in sleep apnoea the oxygen dips are repeated, severe and nightly, and this pattern has been linked for three decades to autonomic, cardiovascular, cognitive and metabolic harm — the research interest in milder patterns as a possible therapy is exactly an argument about dose and pattern, and the human data are preliminary. [source: Mateika research programme summary] Note that CDC guidance treats severe sleep apnoea as needing caution at altitude, with supplemental oxygen possibly needed alongside CPAP. [source: CDC Yellow Book, Hackett & Shlim] Support CPAP adherence with behavioural work rather than encouraging substitutes.
Example language (illustrative): "What happens to your breathing at night may be doing more to your mood than anything we discuss in this room. It's worth getting measured."
Watch for: Clients told by a wellness provider that hypoxia sessions will treat or replace CPAP — that is not supported; abandoning CPAP during a hypoxia course.

4.10 Pregnancy and preconception

Purpose: Pregnancy changes the risk calculation and the advice available is cautious and thin. [source: CDC Yellow Book, Hackett & Shlim]
Steps: Ask directly rather than waiting to be told. For altitude travel, CDC guidance states that no study has shown harm to the fetus from brief trips, but advises confirming that the pregnancy is low risk, generally advises against sleeping at very high altitude, and flags the danger of obstetric complications in remote terrain. [source: CDC Yellow Book, Hackett & Shlim] For device-based hypoxia sessions in pregnancy, treat the position as not established and route to the obstetrician; note that the Russian indications list includes toxicoses of pregnancy, which is a claim from that tradition rather than a safety statement. [source: medi.ru/info/6963] [contested] [uncertain: no current obstetric guidance on hypoxicator use]
Example language (illustrative): "This is one to put to your midwife or obstetrician before you book anything, and I'd rather you ask than that we guess."
Watch for: Fertility-clinic and longevity-clinic packages marketed around conception; a client who has already paid and does not want to ask.

4.11 Naming the danger in DIY hypoxia and breath-hold "training"

Purpose: The riskiest version of this field is the unsupervised one: altitude-simulation masks and secondhand or improvised low-oxygen setups used at home, and the practice of hyperventilating before going underwater or holding the breath for long periods in water. People die from the latter. [source: Red Cross/USA Swimming/Y-USA 2022] [synthesis for home devices]
Steps: Ask whether anything is being done without supervision. State the joint position of the American Red Cross, USA Swimming and the YMCA of the USA: hyperventilating before underwater swimming and prolonged breath-holding in water can cause hypoxic blackout — loss of consciousness from oxygen deprivation — and the organisations deliberately reject the term "shallow water blackout" because depth is irrelevant to the physiology. Their recommendations are that instructors limit breath-holding and submersion, that lifeguards watch for hyperventilating or breath-holding swimmers and respond immediately to anyone motionless in the water, and that swimmers be taught which breath-holding practices are unsafe. [source: Red Cross/USA Swimming/Y-USA 2022] Give no breath-holding technique, no timings and no "safe" version. For home hypoxia devices, point out that the clinical versions exist precisely because the exposure is monitored and automatically adjusted, and that an unmonitored imitation removes the safeguard rather than the risk; direct the client to a physician before any home use. [synthesis] Where a client is a coach, teacher, lifeguard or parent, give them the joint statement to take to their organisation.
Example language (illustrative): "I want to be blunt about one thing. Breath-holding games in water kill people who are fit and competent swimmers, and the warning comes from the lifesaving bodies themselves, not from me being cautious."
Watch for: Competitive or freediving subcultures; teenagers and young men; clients using breath-holding to manage anxiety or to self-punish; anyone practising alone in water; clients who describe blacking out or being "pulled out" and minimise it. Treat a near-miss as a serious adverse event and route it medically.

4.12 Preparing a client for a residential altitude climate treatment

Purpose: Alpine altitude climate treatment for severe uncontrolled asthma is a genuine specialist pathway, with a formal psychological component, and a client's stay can be helped or wasted by psychological preparation. [source: Fieten 2022]
Steps: Clarify referral criteria as published: severe or uncontrolled asthma despite maximal guideline treatment, often oral-steroid dependent, with frequent exacerbations or hospitalisations and reduced exercise tolerance, and currently used largely as a last resort. [source: Fieten 2022] Work before departure on: realistic expectations (reported improvements in control, quality of life, exacerbations, steroid reduction, lung function and fitness come mostly from uncontrolled observational studies, and response and persistence after returning home vary); steroid-related mood effects; fear of breathlessness and exercise avoidance; family separation; and what the client wants to take home. Prepare for re-entry explicitly: plan how self-management, activity and trigger control will survive the return home. Offer, with consent, to liaise with the clinic's psychological service rather than duplicate it.
Example language (illustrative): "The thing people lose is not the gain, it's the setting. Let's decide now which parts of this you are going to keep when you're back in your own kitchen."
Watch for: Hope invested in the stay as a cure; deterioration on return read as personal failure; steroid reduction coinciding with mood change — report it.

4.13 Working with mood in people who live at altitude

Purpose: Clients who have moved to, or live in, high-altitude regions sometimes report mood change that nobody has acknowledged. [source: Kious, Kondo & Renshaw 2018]
Steps: Take a residential and relocation history. Where relevant, state the published position accurately: a review of twelve studies, mostly from the United States, found higher rates of depression and, more strongly, suicide at higher residential altitude, with the highest rates in the intermountain western states; proposed mechanisms are altered serotonin metabolism and brain bioenergetics under chronic low oxygen; the authors call these hypotheses, note that the studies could not adjust for everything (substance use, poverty, cultural differences, firearm access) and that findings outside the United States are inconsistent. Treatments floated in that literature are speculative and unproven. [source: Kious, Kondo & Renshaw 2018] Do not use this as an explanation that displaces formulation or as a reason to change treatment. Raise risk assessment to the standard you would use for any elevated-risk population, including means-safety conversation.
Example language (illustrative): "There is a reported association between living high up and low mood, and nobody can yet say it's the altitude causing it. It doesn't change what we do; it does mean I'm not dismissing what you noticed after you moved."
Watch for: Clients using altitude as a totalising explanation; relocation decisions made on the strength of a news article; elevated suicide risk requiring standard assessment and means-safety planning.

4.14 Working with athletes and altitude or hypoxic training

Purpose: Hypoxic training came out of sport, and the psychological issues in sport are identity, performance anxiety, overtraining and disordered eating rather than hormesis. [source: Serebrovskaya 2002] [synthesis]
Steps: Establish who supervises the training and whether a sports physician is involved. Screen for low energy availability, disordered eating, compulsive exercise and sleep loss; hypoxic work increases the physiological load. Work on the psychological material: fear of losing form, camp separation, comparison with teammates, fused athletic identity, and the meaning of an unmeasurable intervention whose effects on performance are reported as mixed. [source: Zhang et al. 2023] Keep out of the training prescription entirely and refer physiological questions to the sports medicine team.
Example language (illustrative): "I'm not going to have an opinion on your altitude block. I am going to ask what you're eating and sleeping while you do it."
Watch for: Fatigue, mood drop and illness during camps; athletes concealing symptoms to stay in selection; an entourage with no medical member.

4.15 Correcting contested and marketing claims without fighting the client

Purpose: Clients arrive having been told this will reverse ageing, regenerate cells, cure cognitive decline, fix depression or replace medical treatment. [source: Ai Mediq press release 2025] [contested]
Steps: Separate the claim from the person's need. Ask what they are hoping for underneath the claim; name what is supported and what is not (4.4); ask what would count as evidence for them and when they would re-evaluate; agree in advance what they will not stop doing while they try it. Give the device-regulation point plainly: a CE mark covers the device's safety and the manufacturer's stated purpose, not the benefits advertised around it, and a home device marketed with no stated regulatory status, no contraindications and no advice to see a clinician is a consumer product. [source: Ai Mediq company materials; Ai Mediq press release 2025]
Example language (illustrative): "You're not being gullible — the claims are made confidently and they cite studies. What the studies mostly show is that this is worth researching. Can we agree what you'll keep doing regardless?"
Watch for: Escalating spend; a provider who discourages contact with doctors; the client concealing treatment from their physician; shame when it does not work, which stops them telling you.

4.16 Integrating the experience into the psychotherapy

Purpose: Where a client is undergoing hypoxia work or has come back from altitude, the material belongs in the therapy: what the body did, what they concluded about themselves, what changed and why. [synthesis]
Steps: Track the attribution: a client who feels better may credit the device and discount their own behaviour change, exercise, sleep, structure and social contact — research trials of this kind deliberately compare it against the same training without the hypoxic element, and one found no additional benefit. [source: Bayer et al. 2019] Help the client notice what they actually did differently. Use the experience of tolerating difficult bodily sensations under supervision as evidence against catastrophic beliefs, where that is accurate. Use planned altitude trips or clinic attendance as behavioural activation and social contact, which is often the active ingredient.
Example language (illustrative): "Something lifted. Before we hand the credit to the machine, let's list everything else that changed in those weeks."
Watch for: External locus of control hardening; dependence on repeat courses; disappointment when a course ends; bodily-sensation monitoring turning into health anxiety.

4.17 Monitoring and passing on adverse effects

Purpose: You may see the symptoms before the provider does, and the provider may not ask. [synthesis]
Steps: At each session during a course, ask routinely about headache, dizziness, faintness, chest symptoms, palpitations, unusual breathlessness, confusion, sleep change and mood change. Mild dizziness is reported in trials; anything cardiac or neurological, or any loss of consciousness, is an urgent medical matter, not a therapy matter. [source: Behrendt et al. 2022] Tell the client at the outset that you will ask and why. With consent, report to the prescriber and to the provider; where a provider is unregulated and a client has been harmed, discuss the complaint routes available and your own duties.
Example language (illustrative): "I'll ask you the same short list every week while this is going on, and if anything on it shows up we tell your doctor the same day."
Watch for: Symptoms reported as embarrassment rather than as events; a provider who reframes adverse effects as "detox", "adaptation" or "healing crisis" — that framing is a red flag in itself.

5. Handling problems

The sources in this field are physiological and regulatory; almost none address the therapeutic relationship. Everything in this section is marked accordingly.

The client wants you to tell them it works. Decline the role without withdrawing. Give the four-way split in 4.4, say what you do not know, and offer the thing you can genuinely do: help them decide, keep them safe, and keep their other treatment intact. Record what you said. [synthesis]

The provider will not answer questions. Treat non-answers as data. Help the client write three questions (what is monitored, how do I stop it, who here is clinically qualified) and send them in writing. If they go unanswered, say plainly that you cannot support attendance and why, and keep the client. [synthesis]

Medical clearance was refused and the client intends to go anyway. This is their decision. Document the advice given, revisit the specific risk in their case, ask what would make them change their mind, and agree what they will tell someone if they feel unwell. Do not threaten the therapy. Where capacity or risk to life is genuinely in question, follow your usual risk and safeguarding procedure. [synthesis]

The client panics in the mask and refuses to return. Reframe it as information, not failure: the sensations are the ones their system reads as danger. Decide jointly whether the goal is to complete the course at all. If it is, the work is ordinary panic work with the provider's cooperation and an agreed stop signal; if not, the energy goes elsewhere. Never pressure a client to continue a physiological exposure for the sake of completing it. [synthesis]

The course ends and the gains fade. Expect this and name it in advance (4.16). Audit what else changed during the course — routine, movement, attention from staff, being looked after — and rebuild those deliberately. Guard against a cycle of repeat purchase. [synthesis]

The client stops medication or treatment in favour of hypoxia work. Address it directly and early: say what you believe the risk is, ask them to put the decision to the prescriber before acting, and offer to write. If they have already stopped, prioritise re-engagement with the prescriber over being right. [synthesis]

An adverse event happens. Anything cardiac or neurological, any fainting or loss of consciousness, any confusion or unsteadiness at altitude, is medical and urgent, and altitude symptoms that worsen mean descent. [source: CDC Yellow Book, Hackett & Shlim] Afterwards, process it as a frightening bodily event, watch for health anxiety and for avoidance, and support reporting to the provider, the prescriber and, where there is a regulator, to it. [synthesis]

A near-drowning or blackout in water comes to light. Treat it as serious regardless of how the client tells it. Medical review, a direct statement of the risk, removal of the practice, and, where children or a club are involved, safeguarding and a conversation with the organisation using the lifesaving bodies' joint statement.

Rupture after you expressed scepticism. Repair by separating the person from the claim: name that you were talking about the evidence, not their judgement, acknowledge the hope underneath, and ask what they needed from you instead. Agree how you will handle the next disagreement about a treatment they have chosen. [synthesis]

You suspect undiagnosed sleep apnoea and the client resists referral. Work the ambivalence rather than repeating the recommendation: what would a sleep study cost them, what do they fear it would mean, what would change if the fatigue had a physical cause. Offer the referral again later. [synthesis]

A client is a practitioner or coach selling this. Expect a conflict of interest to run through the material. Be clear which hat you are addressing, and where their practice puts others at risk — unsupervised sessions, breath-hold work with young people — raise it as a professional and ethical matter with reference to your own code. [synthesis]

Cultural and spiritual framings. Mountains and "mountain air" carry restorative meaning in many traditions, and the Russian method itself was marketed as Gorny vozdukh, mountain air. [source: medi.ru/info/2712] Attribute such meanings to the tradition or to the client; do not endorse them as physiology and do not strip them. [synthesis]

Not addressed by the sources. None of the cited sources gives guidance on informed consent in commercial hypoxia settings, on psychotherapy alongside a hypoxia course, on managing expectation and attribution, on panic in mask-based exposure, or on therapist documentation. All guidance on those points above is [synthesis]. Obstetric guidance on device-based hypoxia in pregnancy, and regulatory status of these devices outside the EU, remain [uncertain: not verified].
