HOCATT vs Hyperbaric Oxygen Therapy (HBOT): Understanding the Differences
Introduction
If you've been researching advanced wellness technologies, you've probably come across both HOCATT and Hyperbaric Oxygen Therapy (HBOT). At first glance, they may appear similar because both involve oxygen in different ways. However, they are fundamentally different experiences that use very different technologies.
Rather than asking which one is "better", a more helpful question is:
Which approach best suits your goals and preferences?
In this guide, we'll explain how HOCATT and Hyperbaric Oxygen Therapy work, what a typical session feels like, how they differ, and why some people choose one or even both, as part of their broader wellness routine.
What Is Hyperbaric Oxygen Therapy?
Hyperbaric Oxygen Therapy (HBOT) involves breathing oxygen while inside a specially designed chamber that is pressurised above normal atmospheric pressure.
The increased pressure allows more oxygen to dissolve into the blood than would occur under normal conditions. In clinical settings, HBOT has recognised medical applications for certain conditions under appropriate medical supervision. In recent years, some wellness centres have also introduced hyperbaric sessions for general wellbeing and recovery.
During a typical session, you lie comfortably inside the chamber while pressure is gradually increased. Sessions often last between 60 and 90 minutes, and some people notice a sensation similar to the pressure changes experienced during an aeroplane flight.
What Is HOCATT?
HOCATT (Hyperthermic Ozone and Carbonic Acid Transdermal Technology) is a wellness chamber that combines several technologies into a single session.
Unlike Hyperbaric Oxygen Therapy, HOCATT does not use increased atmospheric pressure. Instead, it creates a warm, steam-filled environment while incorporating multiple wellness technologies, which may include:
Transdermal ozone
Carbonic acid
Far infrared heat
Steam
Oxygen breathing through a nasal cannula
Pulsed Electromagnetic Field (PEMF)
Photon light
Aromatherapy
Microcurrent (where available)
During a HOCATT session, your body remains inside the chamber while your head stays outside, allowing you to breathe fresh air comfortably. Sessions typically last around 30 minutes.
Side-by-Side Comparison
HOCATT
Session: ~30 minutes
Position: Sitting
Environment: Warm steam & infrared heat
Pressure: No
Head: Outside the chamber
Oxygen: Nasal cannula
Experience: Multiple wellness technologies in one session
Hyperbaric Oxygen Therapy (HBOT)
Session: 60–90 minutes
Position: Lying down
Environment: Pressurised chamber
Pressure: Yes
Head: Inside the chamber
Oxygen: Pressurised oxygen
Experience: Oxygen therapy in a pressurised environment
How Do They Differ?
Although both experiences involve oxygen, the way they use it is quite different.
HBOT centres on increasing atmospheric pressure while breathing oxygen, which changes how oxygen is delivered throughout the body.
HOCATT takes a different approach by combining several wellness technologies into a single, integrated session that includes warmth, steam, and additional modalities such as far infrared heat, PEMF and aromatherapy.
Rather than viewing them as direct competitors, it's more accurate to think of them as different wellness experiences.
What Does Each Session Feel Like?
A HOCATT Session
Many people describe a HOCATT session as warm, relaxing and comfortable.
You remain seated with your head outside the chamber while your body is surrounded by warm steam. The session may also include gentle aromas and oxygen breathing through a nasal cannula.
The combination of warmth and multiple wellness technologies creates an experience that many people find deeply relaxing.
A Hyperbaric Oxygen Therapy Session
HBOT is typically a quieter experience.
You lie inside a chamber while pressure gradually increases. During the session, you breathe oxygen while relaxing. Because of the change in pressure, you may need to equalise your ears in the same way you would during take-off or landing in an aircraft.
Can HOCATT and Hyperbaric Oxygen Therapy Complement Each Other?
Although HOCATT and HBOT are often compared, they are not designed to do the same thing.
Some people choose to include both as part of a broader wellness routine because each provides a different experience. If you're considering HBOT for a specific medical condition, it's important to discuss this with an appropriately qualified healthcare professional.
Which Experience May Suit You?
You may enjoy HOCATT if you:
Prefer warmth and relaxation.
Like the idea of several wellness technologies in one session.
Prefer a shorter appointment.
Enjoy a spa-like environment.
You may prefer HBOT if you:
Are specifically interested in hyperbaric oxygen therapy.
Are comfortable with a longer session inside a pressurised chamber.
Have discussed HBOT with your healthcare provider for one of its recognised medical applications.
Frequently Asked Questions
Is HOCATT the same as Hyperbaric Oxygen Therapy?
No. Although both involve oxygen, they use different technologies and provide different experiences.
Which session is longer?
A HOCATT session usually lasts around 30 minutes, while HBOT sessions are commonly 60–90 minutes.
Does HOCATT use pressure like HBOT?
No. HOCATT does not rely on increased atmospheric pressure.
Can I combine HOCATT and HBOT?
Some people choose to include both in their wellness routine, depending on their goals and professional advice.
Final Thoughts
HOCATT and Hyperbaric Oxygen Therapy each offer unique approaches to wellness and recovery. Rather than asking which one is "better", it's more useful to understand how they differ and choose the experience that aligns with your preferences and needs.
At Byron Better Health, we offer private HOCATT wellness sessions in a peaceful Byron Bay setting. If you're curious about the experience or would like to learn more, we're always happy to answer your questions.
