Our signature session
Meet the HOCATT
HOCATT stands for Hyperthermic Ozone & Carbonic Acid Transdermal Technology — a personal steam chamber that layers ten technologies into one unhurried seated session. You rest; it runs.

Ten technologies, one seat
What's actually inside a session
Each 30-minute program sequences these technologies so they build on one another — no add-ons to juggle, no extra time to book.
Transdermal ozone
Ozone generated from pure oxygen mixes with the steam and contacts your skin — your head stays outside the chamber the whole time.
Carbonic acid (CO2)
The session opens with carbonic acid, long used in famous European bath houses, which gives skin its warm, pink, post-session glow.
Whole-body warmth
Far-infrared and steam heat gently raise your body temperature — the “H” (hyperthermic) in HOCATT.
High-intensity PEMF
Pulsed electro-magnetic fields run during the session, the same technology as our stand-alone HUGO PEMF service.
Frequency-specific microcurrents
Gentle, programmable microcurrents delivered through the footplates — you pick the program with your team member.
Supplemental oxygen
Received quietly while you rest — no breathing technique to learn, nothing to do but relax.
Essential oil infusions
Your choice of oil joins the steam for the aromatherapy layer of the session.
Photon light & colors
Colored light fills the chamber — each session's program selects the palette.
Ultraviolet irradiation
A built-in UV stage completes the chamber's cycle between and during sessions.
What to expect
Your first visit, step by step
This is the chamber waiting for you in its private room at our Sonora studio — doors open, seat ready. You settle in, the doors close around you with your head comfortably outside, and the session runs while you rest.
Before
Arrive hydrated and skip heavy meals right before your visit. First-timers complete a short health questionnaire, and a SOZO team member walks you through everything.
During
You sit in the private chamber with your head comfortably outside. Steam, carbonic acid, and ozone run in a pre-programmed 30-minute sequence while you rest — most guests say it simply feels like a warm, enveloping steam bath.
After
Rinse off, dress at your pace, and drink plenty of water for the rest of the day. Many guests plan quiet time afterward — the post-session calm is half the fun.
Did you know?
- • The ozone is made on the spot from pure oxygen during your session — nothing is stored or bottled.
- • Carbonic acid bathing has a long history in European thermal-bath tradition; the HOCATT begins every session with it.
- • A session is 30 minutes start to finish — many members visit on a lunch break.
- • Well-known wellness voices including Gary Brecka have spotlighted the HOCATT for combining so many technologies in a single session.
- • The device is CE-certified. It has not been evaluated or approved by the FDA, and our sessions are for general wellness and relaxation — not to diagnose, treat, cure, or prevent any disease.
“One of my favorite bio-stacking devices, I use it every week and can't get enough. It's amazing! … I feel amazing!”
