TL;DR Summary:
HOCATT™ combines ozone, carbon dioxide, oxygen and infrared light in one chamber to support detox, circulation, immune health and pain relief.
One session feels good, but the real shift shows up over a course, which is why we recommend pairing it with PEMF and booking bi-weekly.
Our HOCATT™ 10-Session Wellness Bundle is built around exactly this rhythm.
What actually happens in a HOCATT™ session?
You sit inside the HOCATT™ chamber with your head resting comfortably outside. Approximately 45 to 55 minutes, when combined with PEMF, which is how we recommend it, your body goes through a rotating combination of ozone, carbon dioxide, steam, infrared light and oxygen.
Here’s the order of events.
The chamber gently warms while carbon dioxide (carbonic acid) is introduced, which opens up circulation to your skin.
Once that circulation is primed, ozone gas is infused and absorbed transdermally into your bloodstream.
Infrared light penetrates the skin at the same time, helping to dilate small blood and lymphatic vessels, and you’re given pure oxygen to breathe throughout via two small nasal tubes.
None of it takes effort on your part. You lie back, breathe, and let the technology do the work.

What problems is HOCATT™ actually used for?
HOCATT™ isn’t a single-purpose treatment, and that’s part of why it’s so widely used.
At BTI, clients come to us with a real mix of concerns, and HOCATT™ is commonly used to support:
- Low energy, burnout or a nervous system stuck in overdrive
- General aches, inflammation and slow recovery
- Sluggish circulation
- A run-down immune system
- Hormonal symptoms like disrupted sleep, mood changes or stubborn weight
- Women’s health concerns including endometriosis, fibroids and pelvic pain
- Visible ageing, fine lines, stretch marks and cellulite
- Recovery from intense training or physical strain
If you’ve been carrying one or more of these for a while and nothing seems to be shifting it, this is exactly the kind of whole-body reset HOCATT™ was designed for.
Why one session won’t tell you much, and why the course matters
Most clients feel noticeably lighter and calmer after their very first HOCATT™ session. But if you want the deeper shifts, better sleep, reduced inflammation, visible skin changes, that comes from a course, not a single visit.
Our standard guidance is to book HOCATT™ on a consistent, bi-weekly basis, with a minimum of 48 hours between sessions so your body has time to process and respond.
Most clients complete a 10-session course over roughly five to six weeks.
This lines up with the wider research on ozone therapy. A 2026 narrative review in Frontiers in Medicine on medical ozone found that clinical benefit tends to build with repeated, structured administration rather than a single exposure, particularly in chronic inflammatory conditions.
A separate systematic review and meta-analysis of randomised trials found ozone therapy measurably shifted oxidative stress markers in people with chronic inflammatory disease, again across a course of treatment rather than one session.
That’s the whole logic behind our HOCATT™ 10-Session Wellness Bundle: one session is a nice reset, ten sessions is where you start to feel like a different person.
Why we always pair HOCATT™ with PEMF
This isn’t an upsell, it’s how we’ve always run HOCATT™ at BTI. Combining HOCATT™ with PEMF enhances your body’s natural detoxification process while supporting cellular repair and circulation at the same time.
Think of it this way. HOCATT™ opens the door, warming the body, boosting circulation, and flooding your system with oxygen and ozone. PEMF then works from the inside, using electromagnetic pulses to stimulate your cells directly, supporting pain relief, tissue repair and recovery. One prepares the ground, the other does the rebuilding.
If you want the full picture on how PEMF works and why it’s worth doing alongside HOCATT™, we’ve covered that in What Is PEMF Therapy? How Pulsed Electromagnetic Fields Support Recovery and Pain Relief.
Is HOCATT™ safe?
Ozone therapy has a long safety record and has been studied extensively, including in reviews published through PubMed. It’s considered one of the gentler wellness technologies available, though it isn’t right for everyone.
Certain conditions, including pregnancy, active bleeding disorders, uncontrolled high blood pressure and electrical implants like pacemakers, mean HOCATT™ isn’t suitable, which is exactly why every new client starts with a consultation before their first session.
What clients say after a course of HOCATT™
“I experienced the HOCATT and it was incredible. Trent, Dani and the team put so much care into this place and the health benefits of detoxing with this first class technology truly is a bio-hack of the century.” – Shay Ryan
“I’ve had several sessions of the HOCATT. I can walk around all day now and my joints feel free and pain free. I’m in my seventies.” – Glenda
FAQ
How many HOCATT™ sessions will I need?
It depends on what you’re working on, but we recommend a bi-weekly course with a minimum of 48 hours between sessions. Our HOCATT™ 10-Session Wellness Bundle is built around this exact pattern.
Can I do HOCATT™ if I have a pacemaker or metal implants?
No. Electrical implants and certain metal implants are contraindicated. This is exactly why we run a consultation before your first session, to check your history against the full list of contraindications.
Does it hurt?
No. Most clients describe it as closer to a warm spa session than a clinical treatment.
