What is HOCATT?
HOCATT stands for Hyperthermic Ozone & Carbonic Acid Transdermal Technology. Unlike a traditional sauna, HOCATT is an enclosed wellness sauna where you sit comfortably with your head remaining outside while a programmed sequence of technologies is delivered around the body - these work together within one coordinated 30 minute session, with settings tailored to the individual.

HOCATT Technologies
1) The Foundation
Activated oxygen (O₃) delivered through steam creates full-body exposure. Supports natural wellness processes and systemic vitality.2) The Catalyst
CO₂ is introduced into the chamber, where it reacts with ozone and steam to form carbonic acid. This opens pores, enhances ozone absorption, and supports healthy circulation and oxygen delivery to tissues.3) Core Activation
Elevates core body temperature to promote natural detoxification pathways and deep relaxation.4) Deep Penetration
Infrared wavelengths penetrate 1.5 inches below the skin for deep warmth, supporting comfort and vitality.5) Energy Optimisation
Pulsed electromagnetic fields support cellular energy production and overall system balance.6) Precision Support
Targeted frequencies deliver gentle electrical stimulation to support cellular processes.7) Pure Fueling
Inhaling concentrated oxygen during the session supports enhanced energy and mental clarity.8) Aromatic Enhancement
Selected aromatic compounds delivered through steam for additional wellness benefits.9) Light Energy
Full-spectrum light and specific color wavelengths support photobiomodulation and cellular function.10) Natural Byproduct
As ozone breaks down during the session, it naturally produces UV energy - a byproduct that supports the body’s natural processes.

FAQ’s
Everything you need to know before your first HOCATT session at The Wellness Nurse.
HOCATT stands for Hyperthermic Ozone and Carbonic Acid Transdermal Technology. It is a wellness sauna that combines multiple technologies – including steam, infrared warmth, transdermal ozone, carbonic acid, oxygen, microcurrent, light, and aromatherapy – within one 30 minute programmed session.
PEMF stands for Pulsed Electro-Magnetic Field. It uses gentle electro-magnetic pulses, delivered through two pads positioned above and below the body, creating a whole-body field while you relax comfortably. Small loop attachments can also be positioned around a specific area for a more targeted session.
It’s a non-invasive wellness technology designed to support relaxation, recovery and overall wellbeing.
You sit comfortably inside the sauna with your head remaining outside at all times. The body is gradually warmed using steam and infrared heat while the different HOCATT technologies are introduced throughout the session.
The experience is warm and sauna-like, and the intensity can be adjusted to suit your comfort.
The HOCATT programme itself takes 30 minutes. We allow a 45 minute appointment in total so there is time to change, prepare, settle into the sauna, complete the session and dress afterwards.
Your first visit also includes a health consultation before the session begins.
The PEMF session is a maximum of 12 minutes, tailored to each individual dependent on their concerns/wellness goals. Please allow 20 minutes in total.
