Mild Hyperbaric Oxygen
Twenty-five or fifty minutes in the AirPod at mild pressure, breathing enriched oxygen. Lie down and let it work.
What it is
You lie down inside the AirPod, the door closes, and the chamber gently raises the pressure to around 1.35 bar. That is roughly what your ears feel on a plane. At that pressure you breathe enriched oxygen, which increases how much oxygen dissolves into your blood plasma.
One thing needs to be clear. This is mild hyperbaric equipment used for recovery and wellbeing. It is not clinical hyperbaric oxygen therapy, which runs at far higher pressures, under medical supervision, for specific diagnosed conditions. If you need that, you need a hospital, not a recovery club.
Why people use it
Long recovery blocks
Fifty minutes is the longest single thing on our menu. Members book it after big training weeks, long flights and heavy stretches at work.
Oxygen delivery
The mechanism is straightforward physics. Raise the pressure, and more oxygen dissolves into plasma.
Dead time that counts
You can read, work, watch something or fall asleep. It is the one session here where doing nothing is the entire point.
Two lengths
Twenty-five minutes when you are tight on time, fifty when you want the full block.
How a session works
Screening
Hyperbaric has the longest safety list of anything we do. On your first visit we go through it properly, and that takes a few minutes.
Settle in
Shoes off, everyday clothes are fine. You lie down. The door closes but is never locked from the outside.
Pressurisation
Around five minutes. Your ears will feel it, so swallow, yawn, or pinch and blow gently. Tell us if it hurts and we slow down or stop.
The session
At pressure you can read, work, listen to something, or sleep. Most people sleep.
Depressurisation
A few minutes back to normal pressure. Ears again, usually easier on the way out.
Stand up slowly
Some people feel briefly light-headed. Take a minute before you go.
What to bring
Everyday clothes and shoes off. No lighters, vapes, loose powders or oils, and nothing battery-powered beyond what the team approves. Do not book it with a heavy cold, a blocked nose or an ear infection, because you will not be able to equalise.
Book your hyperbaric session.
Add-ons
Omnilux Contour face mask
- A flexible medical-grade LED face mask. Ask the team whether to wear it in the pod or save it for before or after your session.
Sensate
- A small device that rests on your chest and uses infrasonic resonance with audio to slow your nervous system down. Ask the team about using it during or around your session.
What we know.
What we don’t.
Reasonably established
- Increased pressure increases the amount of oxygen dissolved in blood plasma. That part is settled physics.
- Mild hyperbaric sessions are widely used in sport and recovery settings.
- Ear barotrauma is the most common side effect and it is avoidable with correct equalisation and a slow descent.
Still open, or simply not true
- Evidence for mild pressure on performance and recovery outcomes is limited and still developing.
- Clinical hyperbaric evidence runs at much higher pressures and does not transfer to wellness use. We do not borrow it.
- This is not a treatment for any diagnosed condition.
Safety & screening
This is the session where screening genuinely matters. Some of these rule it out entirely, others need your doctor to sign off first. Bring your questions.
- A collapsed lung, now or untreated
- Pulmonary hypertension
- A perforated eardrum
- Fever
- A viral infection
- Pregnancy
- Been drinking alcohol or using drugs
- Airway disease such as asthma or COPD
- Blocked ear canals or sinuses
- Otitis media, or surgery on the eardrum
- Barotrauma or barotitis media
- Optic neuritis
- Congenital spherocytosis
- Seizures or epilepsy
- Heavy carbon monoxide exposure
- Decompression sickness
- Claustrophobia
- An implanted device such as a pacemaker, pump or neurostimulator, so the manufacturer pressure rating can be checked
- Cisplatin
- Disulfiram, sold as Antabuse
- Doxorubicin, sold as Adriamycin
- Bleomycin
- Mafenide, sold as Sulfamylon
- Nicotine patches or gum
- Opioid painkillers
- Steroids
This list is a starting point, not medical advice. Freezlab does not diagnose or treat medical conditions. When you create an account you also confirm a general health declaration, which covers this list plus a few blanket conditions that apply to every session: any infectious disease, any chronic or acute illness in the last six months, and medication that affects your alertness or fitness to drive. If you are being treated for anything, ask your doctor before you book.
