8 Hyperbaric Oxygen Therapy Myths Indian Wellness Seekers Believe is hbot safe — And What the Science Actually Says
Scepticism about new therapies is healthy. Myths dressed as scepticism are not. Here is the difference.
You have probably heard at least one of these. Maybe from a doctor who dismissed it. Maybe from a wellness influencer who overclaimed it. Maybe from a friend who half-remembered something they read online.
Is HBOT safe? Is it a gimmick? Is it only for serious medical cases? Is it just for the wealthy? India’s wellness market is growing fast, and hyperbaric oxygen therapy is growing with it — but the conversation around it is still tangled in myths that stop people from making genuinely informed decisions.
This article addresses 8 of the most common myths about hyperbaric oxygen therapy that circulate in India — with what the peer-reviewed science actually says about each one. No overclaiming. No dismissal. Just the evidence.
Why HBOT Myths Spread Faster in India
India is a high-scepticism, low-awareness market for HBOT. Most Indians have never heard of it. Those who have encountered it have often done so through one of two extremes: a wellness provider making extravagant claims, or a medical professional dismissing it as unproven.
Neither extreme serves the person trying to make an informed decision. Extravagant claims create unrealistic expectations that lead to disappointment. Blanket dismissals ignore a substantial and growing body of peer-reviewed evidence across 14 FDA-recognised indications.
The myths below sit in the space between these extremes. Correcting them is not about selling HBOT. It is about ensuring that anyone in India who is considering this therapy makes that decision based on what the evidence actually shows — not on what they heard, misread, or assumed.
Myth 1 — “HBOT Is Only for Divers and Hospitals”
The Reality:
HBOT began as a treatment for decompression sickness — the condition divers develop when they surface too quickly. That origin story has stuck in public perception far longer than it deserves to.
The reality is that the FDA and the Undersea and Hyperbaric Medical Society now recognise 14 approved indications for HBOT — including diabetic foot ulcers, radiation tissue injury, carbon monoxide poisoning, crush injuries, severe anaemia, osteomyelitis, and gas embolism. Beyond these clinical applications, HBOT is used globally for athletic recovery, longevity support, cognitive health, and general wellness — all of which are documented in peer-reviewed research.
In India, the evidence of mainstream adoption is visible. Rishabh Pant used HBOT for IPL 2026 preparation. Tiger Shroff shared his HBOT sessions during the filming of Baaghi 3. Anil Kapoor and Samantha Ruth Prabhu have been documented using it. This is not fringe therapy — it is an established tool in elite health and wellness globally.

Myth 2 — “Breathing Extra Oxygen Is Dangerous”
The Reality:
This myth conflates two very different things: oxygen toxicity at extreme pressures and HBOT at clinical wellness pressures. They are not the same.
Oxygen toxicity is a real phenomenon — but it occurs at pressures significantly above those used in wellness HBOT protocols. Clinical wellness sessions typically operate between 1.5 and 2.0 ATA. Oxygen toxicity concerns become relevant at pressures above 2.5 ATA with continuous 100% oxygen exposure, and even then only with prolonged exposure times. The safety protocols used in properly managed HBOT facilities are specifically designed to prevent this.
Research by Wingelaar et al., published in Frontiers in Physiology in 2019, investigated markers of pulmonary oxygen toxicity in HBOT using exhaled breath analysis — and confirmed that standard HBOT protocols produce negligible pulmonary oxygen toxicity markers in healthy individuals. The therapy has a well-documented safety profile across decades of clinical use.

Myth 3 — “One Session Is Enough to See Results”
The Reality:
This myth works in both directions. Some people expect dramatic results from a single session and are disappointed when they don’t arrive. Others dismiss HBOT entirely because a single session produced nothing noticeable.
Both responses misunderstand the biology. HBOT is a cumulative therapy. Each session builds on the last. Stem cells mobilised in session one are amplified by session five. Angiogenesis initiated in week one is maturing by week four. Mitochondrial adaptation requires repeated oxygen pressure signals over time.
The most rigorous real-world documentation of this cumulative effect comes from Bryan Johnson’s 60-session protocol, which produced measurable changes in inflammation markers, VEGF levels, and telomere-associated markers — changes that would not have been possible after a single session. Thom SR’s foundational research on HBOT mechanisms confirmed that the most significant biological effects — stem cell mobilisation, vascular remodelling, and anti-inflammatory cascades — develop across sustained exposure, not single sessions.

Myth 4 — “HBOT Cures Everything”
The Reality:
This is the overclaiming myth — and it is as damaging to HBOT’s credibility as the dismissive myths. Some wellness providers, particularly those selling home chambers, make claims that HBOT evidence does not currently support.
The honest position is this: HBOT has strong, peer-reviewed evidence for its 14 FDA-approved indications. It has promising but preliminary evidence for a broader range of applications including neurological recovery, mental health support, and longevity. And for some conditions, the evidence remains insufficient to draw meaningful conclusions.
HBOT is most appropriately understood as a supportive therapy — one that works alongside other treatments, not instead of them. Justin Bieber uses it alongside psychiatric care for anxiety and depression. Djokovic used it alongside physiotherapy for his knee recovery. Athletes use it alongside nutrition and training. The therapy amplifies other interventions; it does not replace them.

Myth 5 — “Soft Chambers Are the Same as Hard Chambers”
The Reality:
This is one of the most technically important myths to correct — especially given the growth of home HBOT equipment marketing in India.
Hard-shell chambers — the type used in clinical and properly equipped wellness settings — typically operate at 1.5 to 3.0 ATA with 100% medical-grade oxygen delivered through a mask or hood. This is the pressure and oxygen concentration used in all peer-reviewed HBOT research.
Soft-shell portable chambers — the inflatable units marketed for home use — typically reach only 1.3 ATA and use ambient air enriched with an oxygen concentrator, producing roughly 24 to 40% oxygen rather than 100%. At these pressures and oxygen concentrations, the plasma-dissolved oxygen increase — the mechanism behind HBOT’s documented benefits — is significantly reduced compared to clinical hard-shell protocols.
Fife et al.’s 2016 review in Plastic and Reconstructive Surgery, which reviewed the evidence base for HBOT across all major indications, was based entirely on research conducted in hard-shell chambers at clinical pressures. The evidence for soft-shell mild HBOT as a clinical intervention is substantially weaker. This does not mean soft chambers produce no benefit — but they should not be marketed as equivalent to clinical HBOT.

Myth 6 — “HBOT Is Only for the Rich”
The Reality:
This myth was more true five years ago than it is today. And in India’s context, it was largely accurate until very recently — because the only HBOT available was in hospital settings, at clinical costs, for specific medical indications.
The wellness HBOT landscape in India is changing. The growth of organised wellness HBOT networks — designed specifically to make structured, protocol-based HBOT accessible outside of hospital settings — is bringing per-session costs down significantly. A session at a properly equipped wellness HBOT facility in India is increasingly comparable in cost to premium physiotherapy or advanced spa treatments.
The per-session cost concern is also partly a protocol misunderstanding. People assume they need the same 40 to 60 session protocols that elite athletes use. For general wellness support — recovery, energy, sleep, inflammation — shorter introductory protocols of 10 to 20 sessions are often sufficient to produce meaningful early benefits, at a total cost that is within reach for India’s growing upper-middle-class wellness consumer.

Myth 7 — “HBOT Has No Science Behind It”
The Reality:
This is the most comprehensively wrong myth on this list — and it is worth addressing directly because it is often the last line of defence for people who have already decided to dismiss HBOT without investigating it.
HBOT has been studied in peer-reviewed research for over 60 years. The Undersea and Hyperbaric Medical Society maintains a clinical evidence base across 14 approved indications. Research institutions including Tel Aviv University, the University of Texas, Johns Hopkins, and multiple Indian medical institutions have published peer-reviewed HBOT research. The PubMed database contains thousands of HBOT-related publications.
The wound healing evidence is particularly strong. Research by Bhutani and Vishwanath, published in the Indian Journal of Plastic Surgery in 2012, reviewed the evidence for HBOT in wound healing — confirming its role in oxygenating ischaemic tissue, stimulating collagen synthesis, and reducing infection risk in chronic wounds. This is Indian peer-reviewed research, published in an Indian journal, confirming HBOT’s evidence base.

Myth 8 — “HBOT Is Risky for the Heart”
The Reality:
This myth likely originates from the association between pressure changes and cardiovascular stress — a reasonable concern on the surface, but one that does not reflect the actual cardiovascular profile of clinical HBOT at standard wellness pressures.
HBOT at standard pressures (1.5 to 2.0 ATA) produces a mild, temporary increase in blood pressure and a slight decrease in heart rate due to vasoconstriction — both of which are well within normal physiological ranges and resolve immediately after the session ends. For healthy adults, these changes are clinically insignificant.
Research by Goyal and Cooper, published in StatPearls in 2019, reviewed the cardiovascular effects of hyperbaric oxygen — confirming that HBOT at standard clinical pressures is safe for the vast majority of patients, including those with stable cardiovascular conditions managed under medical supervision. Specific contraindications exist for certain conditions — untreated pneumothorax, some chemotherapy agents, and severe claustrophobia among them — but these are well documented and screened for in properly managed facilities.

The Real Questions to Ask Before Starting HBOT in India
Correcting myths is the first step. The second step is knowing what questions to actually ask.
Before beginning any HBOT protocol in India, the questions that matter are these. What pressure does the chamber operate at? Is it a hard-shell clinical chamber or a soft-shell portable unit? What oxygen concentration is delivered — 100% medical-grade or ambient enriched? Is the facility supervised by trained professionals? What protocol is recommended for your specific goal — and is that recommendation based on evidence or on selling you more sessions?
The answers to these questions separate a serious, evidence-based HBOT provider from one making claims their equipment cannot support. In India’s rapidly growing wellness market, the difference matters.

Frequently Asked Questions
Is HBOT safe for the general public in India?
For healthy adults without specific contraindications, HBOT at clinical wellness pressures (1.5 to 2.0 ATA) has a well-documented safety profile. Side effects are generally mild and temporary — primarily ear pressure during pressurisation, similar to what you experience on an aeroplane, and occasional mild fatigue after early sessions. Specific contraindications exist — including untreated pneumothorax, certain medications, and severe claustrophobia — and should be screened for before beginning any protocol. For anyone with an existing medical condition, consulting a doctor before starting HBOT is the appropriate first step. For the foundational science on what HBOT involves, read our guide on what is hyperbaric oxygen therapy.
How many sessions does HBOT actually need to work?
It depends on your goal. For general wellness support — improved recovery, energy, sleep, and inflammation reduction — most users notice meaningful early benefits within 5 to 10 sessions, with deeper physiological changes appearing after 20 or more. For athletic injury recovery, protocols of 10 to 20 sessions are common. For longevity and deep biological change — the type Bryan Johnson pursued — 40 to 60 sessions are typically required. Our guide on the HBOT results timeline breaks down what changes at each stage.
What is the difference between soft and hard HBOT chambers?
Hard-shell chambers operate at 1.5 to 3.0 ATA with 100% medical-grade oxygen — the pressure and oxygen concentration used in all peer-reviewed HBOT research. Soft-shell portable chambers typically reach only 1.3 ATA and use ambient air enriched with an oxygen concentrator, producing roughly 24 to 40% oxygen. The plasma-dissolved oxygen increase that drives HBOT’s documented benefits is significantly smaller in soft-shell protocols.
