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.
