HOCATT™ Ozone Sauna
A non-invasive, whole-body wellness technology that combines transdermal ozone, far infrared, carbonic acid, and photon light in a single 30-minute session — the HOCATT™ Power of 10. The HOCATT™ ozone sauna at SynergyO3, serving Encinitas, San Diego, and North County. Often searched as HOCATT™ near me, this physician-supervised HOCATT™ treatment is available directly at our Encinitas clinic.
One session. Ten technologies.
Most wellness tools do one thing at a time. HOCATT™ layers ten modalities into a single 30-minute session, so the body receives a coordinated, whole-body input under physician oversight.
A steam chamber, with your head out.
You sit in a personal steam cabin while your head stays outside in fresh, filtered air. Warm steam gently opens the skin so transdermal ozone and the other modalities are delivered to the body — not inhaled. Mechanism, not magic.
Head out · fresh air
You breathe room air the whole time — ozone stays on the body, not the lungs.
Steam opens the skin
Gentle heat prepares the skin so modalities absorb transdermally.
Seated · 30 minutes
A single, comfortable session start to finish.
Ten modalities, layered.
The HOCATT™ Platinum combines multiple wellness technologies in one cabin. Here’s what’s working together during a session.
Transdermal ozone
Ozone delivered to the body through warmed skin.
Steam hyperthermia
Warm steam gently raises skin temperature.
Far infrared
Radiant warmth that penetrates comfortably.
Carbonic acid (CO₂)
Supports the feeling of circulation at the skin.
Photon light
Visible red/near-infrared light at the skin.
PEMF frequency
Pulsed electromagnetic field option.
Breathable oxygen
Concentrated oxygen to finish the session.
Aromatherapy
Optional essential-oil aromatics.
Charcoal air filter
Filtered air at the head opening.
Physician oversight
Dose and candidacy set by Dr. Volpp.
Warm skin, controlled dose.
Steam opens the skin; transdermal ozone and carbonic acid are delivered to the body while far infrared adds gentle radiant warmth. Every input is dose-controlled and physician-supervised — and because your head stays outside the cabin, ozone is kept off the lungs by design.
A sealed, single-user cabin. Session length, temperature, and ozone concentration are set per person. Being explored for circulation, recovery, and general well-being; individual experiences vary.
A controlled stressor.
Heat and ozone are mild, controlled stressors. In the right dose, the body adapts to them — the principle is called hormesis. Too little does nothing; too much is counterproductive. The window in between is exactly why dose and physician oversight matter.
Thirty minutes, start to finish.
Quick check-in
A brief review of your goals and candidacy with the team.
Head out, seated
You take a seat in the cabin; your head stays outside in fresh air.
Steam + the Power of 10
Roughly twenty minutes of layered modalities at your set dose.
Breathe concentrated oxygen
A short oxygen finish to close the session.
Rest and plan
Dr. Volpp reviews how you responded and adjusts future sessions.

Common Questions
Frequently Asked Questions
Is HOCATT™ covered by insurance?
HOCATT™ is a wellness technology, not an FDA-approved medical treatment, so it is not typically covered by insurance. Our team can provide a receipt with treatment codes if you'd like to submit it to an HSA/FSA or insurance plan for possible reimbursement — coverage varies by plan.
Is HOCATT™ safe?
Yes — the HOCATT™ is a head-out design, so you breathe filtered room air the entire session while ozone stays on the body, not the lungs. Every session is physician-supervised, with dose, temperature, and candidacy set individually by Dr. Volpp.
How often should I do HOCATT™ sessions?
Frequency depends on your goals — some patients use HOCATT™ for periodic recovery and general wellness, while others follow a more structured series as part of a broader protocol. Dr. Volpp reviews your health profile and recommends a cadence suited to you.
What should I expect during my first HOCATT™ session?
After a quick check-in, you'll sit in the cabin with your head outside in fresh air while roughly twenty minutes of layered modalities run at your set dose, followed by a short oxygen finish. The full session takes about 30 minutes, and Dr. Volpp reviews how you responded afterward.
