What is Hyperbaric Oxygen Therapy (HBOT)? Benefits, Sessions & What to Expect

Hyperbaric Oxygen Therapy (HBOT) is becoming increasingly popular across the UK as more people explore proactive ways to support recovery, wellbeing and performance.

Once mainly associated with medical environments, elite athletes and specialist recovery clinics, HBOT is now widely used by individuals looking to prioritise rest, recovery and overall wellness.

But what exactly is Hyperbaric Oxygen Therapy? How does it work, what does an HBOT session feel like, and what are the potential benefits?

In this guide, we explain everything you need to know about Hyperbaric Oxygen Therapy (HBOT), including how it works, what to expect during a session and whether it could support your wellbeing journey.

What is Hyperbaric Oxygen Therapy (HBOT)?

Hyperbaric Oxygen Therapy (HBOT) is a treatment that involves breathing oxygen in a specially designed pressurised chamber.

The increased air pressure allows your body to absorb more oxygen than it would under normal conditions. This oxygen is then carried more efficiently throughout the body.

Normally, oxygen travels through the bloodstream via red blood cells. During an HBOT session, oxygen can dissolve more effectively into blood plasma, allowing increased oxygen delivery to tissues, muscles and areas of the body that may benefit from additional support.

In simple terms, Hyperbaric Oxygen Therapy is designed to help optimise oxygen levels in the body to support natural recovery and wellbeing processes.

While HBOT has traditionally been used in clinical and medical settings, it is increasingly becoming part of wellness and recovery routines.

How Does Hyperbaric Oxygen Therapy Work?

During an HBOT session, you sit or lie comfortably inside a hyperbaric chamber while the pressure is gradually increased.

As pressure rises, your body can absorb oxygen more effectively, supporting circulation and oxygen delivery throughout the body.

Many people compare the sensation to being on an aeroplane during take-off or landing, where your ears may gently pop due to pressure changes.

Sessions are designed to feel calm and relaxing, with many people using the time to rest, listen to music, watch content or simply switch off from daily life.

What Are the Potential Benefits of Hyperbaric Oxygen Therapy?

People choose Hyperbaric Oxygen Therapy for many different reasons depending on their individual goals and lifestyle.

Recovery and Wellness Support

Many individuals incorporate HBOT into their wellness routines to support recovery after exercise, demanding schedules or busy lifestyles.

Performance and Physical Recovery

Athletes and active individuals sometimes use Hyperbaric Oxygen Therapy as part of their wider recovery and performance plans.

Energy and General Wellbeing

Some people report feeling refreshed, recharged or more energised following regular sessions, particularly when used consistently as part of a wellbeing routine.

Dedicated Time to Relax and Recover

For many people, an HBOT session becomes an opportunity to pause, relax and prioritise recovery in a calm environment.

Everyone’s experience is different, and outcomes can vary depending on individual circumstances, lifestyle and goals.

What Happens During an HBOT Session?

If you are considering Hyperbaric Oxygen Therapy for the first time, it is completely normal to wonder what actually happens during a session.

Before Your Session

Before beginning treatment, a trained professional will explain the process, answer any questions and guide you through what to expect.

Comfortable clothing is usually recommended, and you will be shown how the hyperbaric chamber works before your session begins.

During the Session

Once inside the chamber, the pressure gradually increases. You may notice a gentle popping sensation in your ears, similar to changes in altitude when flying.

Most people settle into the experience quickly once the pressure adjusts.

An HBOT session is typically calm and relaxing, and many people choose to:

• Listen to music or podcasts
• Watch content on a device (depending on clinic guidance)
• Read
• Rest or meditate

Session lengths may vary depending on your individual treatment plan.

After Your Session

Many people return straight to their normal daily activities after treatment.

Some individuals describe feeling relaxed or refreshed after a session, while others notice benefits over time with consistency.

Is Hyperbaric Oxygen Therapy Safe?

When carried out by trained professionals using appropriate equipment, Hyperbaric Oxygen Therapy is generally considered safe.

As with any wellness or recovery treatment, it is important to discuss any health concerns or medical history before beginning treatment.

Some people may experience temporary ear pressure during sessions, but trained staff can explain simple techniques to manage this comfortably.

If you are unsure whether HBOT is right for you, speaking with a qualified provider is the best place to start.

How Much Does Hyperbaric Oxygen Therapy Cost?

The cost of Hyperbaric Oxygen Therapy can vary depending on several factors, including:

• Session length
• Location
• Type of chamber used
• Whether sessions are booked individually or as part of a package

Because treatment plans are often personalised, many clinics recommend speaking with their team to discuss the most suitable option for your individual goals.

Rather than focusing solely on price, it is often helpful to consider the overall experience, level of professional support and treatment approach when choosing a provider.

People explore HBOT for a wide range of personal reasons.

This may include:

• Busy professionals looking to prioritise recovery
