No other device combines transdermal ozone, PEMF, CO₂, far infrared, photon light, hyperthermia, steam, aromatherapy, frequency therapy, and EWOT in a single 30-minute session.
Dr. Volpp personally reviews your health history and goals to configure each HOCATT® session — modality intensity, ozone concentration, and temperature calibrated to your biology.
By flooding the body with ozone and hyperthermia simultaneously, HOCATT® triggers an acute oxidative stress response that activates the body's own antioxidant and regenerative cascade.
HOCATT® stands for Hyperthermic Ozone and Carbonic Acid Transdermal Therapy. It's a full-body chamber that delivers 10 therapeutic modalities simultaneously — addressing circulation, immune function, detoxification, pain, energy, skin health, and cellular aging in a single session.
Each modality targets a specific biological system. Together, they create a compounding therapeutic effect that no single device can replicate. This is why 30 minutes in HOCATT® delivers outcomes that take months through other means.
O₃ delivered directly through open pores into lymph, tissue, and microcirculation. Activates antioxidant enzymes (SOD, catalase, glutathione), stimulates immune function, eliminates pathogens, and kickstarts the Nrf2 pathway — the master regulator of cellular defense. The most powerful modality in the chamber.
Carbonic acid (CO₂ dissolved in steam) opens skin pores and triggers the Bohr effect — enhancing oxygen release from red blood cells into peripheral tissue. Improves microcirculation and nutrient delivery. The same mechanism used in high-altitude athletic training camps.
Delivers oscillating electromagnetic fields that restore cellular membrane voltage — the electrical charge that drives nutrient transport, waste removal, and cellular signaling. Reduces inflammation, improves nerve conduction, and accelerates tissue recovery. Included at no extra charge.
Long-wave infrared energy penetrates 4–5 cm below the skin surface — deeper than traditional sauna — to elevate core temperature at the tissue level. Drives heavy metal mobilization via sweat, improves mitochondrial function, and triggers heat shock proteins that repair damaged cellular proteins.
Multiple wavelengths of visible and near-infrared light stimulate cytochrome c oxidase in mitochondria — the enzyme responsible for ATP (cellular energy) production. Clinically validated for wound healing, skin rejuvenation, and neurological support. Delivered across the full body simultaneously.
Controlled elevation of core body temperature to 38.5–40°C creates a therapeutic fever response. Heat disrupts pathogen replication, activates immune surveillance, increases white blood cell activity, and signals cellular repair cascades. Particularly beneficial for chronic infections, Lyme, and immune dysregulation.
Steam opens dermal pores and creates the hydrothermal medium through which ozone and carbonic acid absorb. Simultaneously promotes active sweating for toxin elimination and supports respiratory function via steam inhalation. Adds a profound relaxation component that reduces cortisol and activates parasympathetic tone.
Essential oil diffusion within the chamber reaches respiratory mucosa during each breath — with clinical oils selected for your session goal. Anti-inflammatory (eucalyptus), immune-supportive (tea tree), calming (lavender), or energizing (peppermint) blends customized to your protocol.
Low-frequency electrical currents delivered through the chamber target specific tissue resonance frequencies associated with pathogens, toxins, or cellular dysfunction. Complements ozone's antimicrobial mechanisms at the frequency level. Optional add-on for targeted therapeutic goals.
Nasal oxygen delivery during the session elevates blood oxygen saturation while the body is under controlled hyperthermia stress. Creates a hyperoxic state that dramatically improves cellular respiration, cognitive performance, and endurance recovery. The final compound in the HOCATT® synergy equation.
Most patients feel deeply relaxed during their session and report an energy lift within 1–2 hours afterward. No recovery time required. First-timers receive a lower ozone concentration while the body acclimates.
The pod fills with steam and CO₂ as your core temperature begins to rise. Pores open. Carbonic acid triggers the Bohr effect, priming circulation for ozone delivery.
Ozone concentration reaches therapeutic levels. Transdermal absorption begins through the now-open pores. Far infrared penetrates deep tissue simultaneously.
All 10 modalities running simultaneously. PEMF pulses restore cellular voltage. Photon light stimulates ATP. Temperature peaks at the physician-set target (typically 38.5–39°C).
Oxygen delivery via nasal cannula continues. Hyperthermia drives heat shock protein activation. The body is in its maximum antioxidant response state.
Chamber temperature lowers. Steam vents. PEMF and photon continue. Body transitions from stress response to recovery — the window where regenerative signaling peaks.
Drink 16–24 oz water immediately after. A mild detox response (fatigue, warmth) in the first hour is normal and resolves quickly. Most patients report energy lift by hour 2.
HOCATT® addresses systemic biology — so its applications span a wide range of conditions and goals. Dr. Volpp's physician oversight ensures each patient's protocol is targeted, not generic.
Mitochondrial dysfunction is the root of most fatigue. HOCATT®'s photon light + ozone + EWOT combination directly targets ATP production and cellular respiration — often producing noticeable energy improvement within 2–4 sessions.
Ozone at therapeutic levels activates innate immune surveillance and stimulates NK cell and white blood cell activity. Ideal for seasonal illness prevention, post-viral recovery (including long COVID), and chronic immune suppression.
Hyperthermia + far infrared + steam drives active sweating for the excretion of heavy metals, lipid-soluble toxins, and environmental chemicals that standard kidney filtration cannot clear. Supported by systemic ozone liver-protective antioxidant effects.
PEMF reduces prostaglandin-mediated inflammation. Ozone downregulates inflammatory cytokines. Far infrared penetrates joints and deep tissue for lasting pain reduction. Particularly effective for fibromyalgia, arthritis, back pain, and post-injury recovery.
Transdermal ozone triggers full-body cellular turnover and collagen stimulation from the inside out. CO₂ improves skin microcirculation and nutrient delivery. Photon light drives mitochondrial rejuvenation at the dermal level. A systemic skin reset between aesthetic sessions.
Carbonic acid and ozone together create a powerful circulatory improvement — expanding microvessels, improving red blood cell deformability, and reducing oxidative damage to arterial walls. Hyperthermia amplifies cardiac output and peripheral flow for 4–6 hours post-session.
Hyperthermia elevates metabolic rate during and for hours after the session. Far infrared and ozone improve insulin sensitivity and mitochondrial efficiency. HOCATT® amplifies this with simultaneous modalities.
EWOT and ozone improve cerebral oxygenation and blood flow. PEMF has documented neuro-protective effects. Photon near-infrared penetrates the skull to stimulate neurotrophic factors. Particularly beneficial for brain fog, cognitive decline, post-concussion, and mood disorders.
Post-training HOCATT® sessions accelerate lactic acid clearance, reduce DOMS (delayed onset muscle soreness), restore cellular voltage via PEMF, and drive antioxidant enzyme activation. Used by elite athletes for recovery compression and pre-competition optimization.
HOCATT® is not appropriate for active G6PD deficiency, active hyperthyroidism, hemophilia, myasthenia gravis, severe hypertension, or pregnancy. Patients with pacemakers, metal implants, or recent surgery require physician clearance. All contraindications are reviewed by Dr. Volpp before your first session.
HOCATT® delivers transdermal ozone — through the skin, into peripheral tissue and lymphatic circulation. EBOO (Extracorporeal Blood Oxygenation and Ozonation) delivers ozone directly into the bloodstream via IV — reaching organs, bone marrow, and systemic circulation at concentrations impossible transdermally.
Together, they address every compartment of the body simultaneously. SynergyO3 is one of the only clinics in San Diego County offering both under physician supervision — and the only clinic in Encinitas providing the complete regenerative ozone stack.
Learn About EBOO Therapy →Board-certified physician with training in integrative and functional medicine. Dr. Volpp personally reviews every HOCATT® patient's health history, medications, and goals before their first session — and adjusts protocols as treatment progresses.
"HOCATT® is one of the most clinically versatile tools I've encountered in integrative medicine. When I prescribe it properly — calibrated to that patient's biology — I see effects on energy, immune function, and skin health that would otherwise require months of individual treatments."
"After 4 sessions I felt like I had more energy than I'd had in years. The brain fog lifted. My skin was clearer. I didn't expect it to work this fast — but Dr. Volpp set the right protocol from day one."

Yes. All new HOCATT® patients begin with a physician-led intake review with Dr. Volpp. Your health history, current medications, and goals are reviewed to confirm HOCATT® is appropriate and to set the right ozone concentration, temperature, and modality configuration for your first session.
Most patients describe it as a deeply relaxing experience — similar to a warm, aromatic sauna, but more energizing. You'll feel warmth from the infrared and steam, the PEMF as mild tingling in some areas, and the photon light is visible. Your head remains outside the chamber at all times so you breathe fresh oxygen comfortably.
Many patients report noticeable energy improvement after their first session. For deeper systemic outcomes — immune support, skin health, chronic fatigue — a series of 6–10 sessions over 3–5 weeks is typically recommended, followed by weekly or bi-weekly maintenance. Dr. Volpp will recommend a protocol at your intake.
HOCATT® is extremely well-tolerated when properly physician-prescribed. Some patients experience mild detox symptoms in the first 1–2 sessions (brief fatigue or warmth after the session) as ozone activates antioxidant pathways. These are transient and resolve within hours. Ozone concentration is started conservatively for new patients.
Patients with pacemakers or certain active electronic implants require physician clearance before HOCATT® due to the PEMF component. Passive metal implants (screws, plates) are generally not contraindicated at the frequencies used, but are reviewed case by case by Dr. Volpp.
A traditional sauna delivers heat only. HOCATT® delivers heat plus transdermal ozone (antimicrobial, antioxidant, immune activating), CO₂ carbonic acid (Bohr effect microcirculation), PEMF (cellular voltage restoration), photon light (mitochondrial ATP), and EWOT (hyperoxic respiration). They are different categories of intervention.
In some protocols, yes — and the combination is powerful. EBOO provides systemic intravenous ozone while HOCATT® addresses transdermal delivery and the 10 additional modalities. However, combination sessions are physician-determined based on your health status and tolerance. Not all patients are candidates for same-day dual ozone therapy.
Arrive well-hydrated (drink 16 oz of water 30 minutes prior). Avoid heavy meals for 2 hours. Wear comfortable, loose clothing. Remove all jewelry and metal accessories before entering. Bring or plan for post-session rehydration — at least 16 oz of water immediately after. Notify our team of any changes in medications or health since your last visit.
