What Does the Treatment Involve?
Before your first session, we will talk you through the treatment and make sure you understand what to expect. You will be comfortably positioned inside the chamber before it is gradually pressurised. As the pressure increases, you may experience a sensation of fullness or pressure in your ears, similar to the feeling you get when an aeroplane takes off or lands. Your practitioner will explain simple techniques to help you equalise the pressure. Once the chamber reaches the treatment pressure, you can relax for the remainder of your session. At the end, the chamber is gradually depressurised before you leave.The treatment is intended to feel calm and comfortable rather than intense.
What Does It Feel Like?
For many people, the experience is surprisingly relaxing. The most noticeable sensation is usually the change in pressure in the ears during the beginning and end of the session. Once you have acclimatised, you can simply relax inside the chamber. Depending on the session, you may choose to listen to music, read or simply switch off for a while. For some people, the appeal is as much about having dedicated time to pause and reset as it is about the treatment itself.
Why Do People Choose Hyperbaric Therapy?
Hyperbaric therapy has become increasingly popular as part of broader wellness and recovery routines.
People choose it for a variety of personal reasons, including:
- Supporting their overall wellbeing
- Incorporating relaxation into a busy lifestyle
- Adding another element to their recovery routine
- Enjoying dedicated time to rest and switch off
- Exploring complementary approaches to wellbeing
- Feeling refreshed and relaxed following a session
Everyone responds differently, and we do not promise a particular outcome. Our approach is to explain what the treatment may offer while keeping expectations realistic.
Is Hyperbaric Therapy the Same as Medical HBOT?
No. This distinction is important. Medical hyperbaric oxygen therapy is used in specialist medical settings for specific conditions and follows established treatment protocols. Mild hyperbaric therapy uses lower pressures and should not be assumed to provide the same treatment or oxygen exposure as hospital-based HBOT. The Undersea & Hyperbaric Medical Society distinguishes mild hyperbaric treatment from conventional hyperbaric oxygen therapy and notes that evidence for medical treatment at these lower pressures is limited. For this reason, we position the treatment at The Clinic as a wellness and recovery experience, rather than claiming that it treats or cures medical conditions.
What Are the Potential Benefits?
There is ongoing research into hyperbaric therapy and its potential effects. However, evidence varies considerably depending on the condition being investigated, the pressure used, treatment protocol and the individual. We therefore avoid making exaggerated claims.
The benefits people may be interested in include:
Relaxation
The chamber provides an opportunity to slow down and enjoy some uninterrupted downtime.
Recovery and wellbeing
Some clients choose to incorporate sessions into their wider approach to recovery and wellbeing.
A sense of refreshment
Some people report feeling relaxed or refreshed following a session, although individual experiences vary.
Time for yourself
In a busy world, simply having dedicated time to pause, relax and step away from everyday demands can be valuable. These are potential experiences rather than guaranteed medical outcomes.
Can It Help With Energy?
This is a question we are frequently asked. Some people choose hyperbaric therapy because they are looking for ways to support their general wellbeing and recovery and may report feeling refreshed following treatment. However, we would not promise that a session will increase your energy levels. Persistent tiredness or unexplained fatigue should always be investigated medically rather than relying on a wellness treatment.
Can It Help With Recovery?
Hyperbaric therapy is sometimes incorporated into personal recovery routines. People may choose it alongside other lifestyle measures such as good nutrition, hydration, adequate sleep and appropriate exercise. However, the evidence for specific recovery claims at mild pressures is still developing. We therefore recommend viewing the treatment as one part of a broader wellbeing approach, rather than a stand-alone solution.
How Long Does a Session Take?
Your practitioner will explain the expected duration of your session before treatment.
Your appointment will include time for:
- A pre-treatment suitability check
- An explanation of the chamber
- Getting comfortably positioned
- Gradual pressurisation
- The main treatment period
- Gradual decompression
- A post-treatment check
Your first appointment may take slightly longer because we want you to feel completely comfortable with the process.
How Many Sessions Do I Need?
There is no universally recommended number of sessions for mild hyperbaric therapy as a wellness treatment. Some people choose an individual session, while others prefer to incorporate regular treatments into their wellbeing routine. We will discuss your reasons for considering treatment and help you decide what is appropriate for you. We do not believe everyone needs a course of treatment simply because one is available.
Is It Painful?
The treatment itself should not be painful. You may notice pressure in your ears while the chamber is being pressurised or depressurised. This is normal, but it should not become painful. You will be shown how to equalise your ears, and you should tell your practitioner immediately if you experience discomfort or are unable to equalise the pressure.
Are There Any Risks or Side Effects?
As with any treatment, there are potential risks.
Possible effects include:
- Ear pressure or discomfort
- Difficulty equalising the ears
- Temporary ear discomfort
- Sinus pressure
- Temporary changes in hearing
- Light-headedness
- Feeling tired
- Claustrophobia or anxiety
- Rare pressure-related injury
Most people tolerate pressure changes well, but suitability varies from person to person. The chamber also has specific safety requirements, particularly regarding items that can be taken inside and appropriate fire-safety procedures. Your practitioner will explain these requirements before treatment.
Who May Not Be Suitable?
A suitability assessment will be completed before treatment.
Please tell us if you have:
- Ear problems
- Sinus problems
- Lung or respiratory conditions
- Recent surgery
- Significant medical conditions
- Pregnancy or possible pregnancy
- Difficulty equalising your ears
- Claustrophobia
- Any previous problems with hyperbaric treatment
- Any medications or medical treatment that may be relevant
If there is any uncertainty about whether the treatment is appropriate for you, we may recommend that you speak to your GP or another healthcare professional before proceeding.
What Should I Wear?
You will be given clear instructions before your session about suitable clothing and what can and cannot be taken into the chamber. Because hyperbaric environments have specific safety requirements, these instructions must always be followed. Your practitioner will make sure you understand everything before you enter the chamber.
Can I Eat Before Treatment?
You can generally eat normally before your appointment. We recommend avoiding a very large meal immediately beforehand so that you feel comfortable during the session. Staying appropriately hydrated is also sensible. If you have any specific dietary or medical considerations, please discuss these with your practitioner.
What Happens Afterwards?
Most people can continue with their normal day following a session. You may feel relaxed, calm or refreshed afterwards, although everyone responds differently. We recommend allowing yourself a little time to enjoy the experience rather than treating your appointment as something you need to rush in and out of.
Can Hyperbaric Therapy Replace Medical Treatment?
No. Hyperbaric therapy offered at The Clinic should not replace medical diagnosis, prescribed medication, medical treatment or advice from your GP or consultant. If you have a health concern, unexplained symptoms or a diagnosed medical condition, you should seek appropriate medical advice. If you are considering hyperbaric treatment specifically for a recognised medical indication, you should be assessed by an appropriate medical hyperbaric service.
What About Claims You See Online?
There are many claims online about hyperbaric therapy. You may see it promoted for everything from ageing and inflammation to neurological conditions, chronic illness, fatigue and recovery. Some areas are being researched, but that does not mean that every claim has been scientifically established. At The Clinic, we believe it is important to separate interesting research from proven treatment outcomes. We will never tell you that a wellness treatment can cure a medical condition simply because there is a study or theory surrounding it. We would rather give you honest, balanced information so that you can decide whether the treatment is right for you.
