What Is the HOCATT Sauna?
The HOCATT (Hyperthermic Ozone & Carbonic Acid Transdermal Technology) is a multi-modality wellness system used in a spa-like setting. A typical session combines several comfort-oriented modalities—such as steam, carbonic acid exposure, far-infrared warmth, pulsed electromagnetic fields (PEMF), and oxygen inhalation— while you sit in a chamber with your head outside.
Important information: Ozone-based services are not FDA-approved to diagnose, treat, cure, or prevent any disease. We offer HOCATT sessions as adjunctive wellness services. Evidence varies by person and modality, and individual responses differ.
What Happens in a Session?
Sessions are about 30 minutes (60-minute appointment). After you’re comfortably seated, the chamber provides controlled warmth and steam; carbonic acid exposure helps create a humid environment. Depending on your plan, PEMF and oxygen inhalation may be included. Your clinician will review goals, comfort preferences, and precautions beforehand.
Why Do People Choose It?
- For a relaxing, spa-like experience with warmth and steam.
- As part of a general wellness routine focused on comfort and recovery.
- To explore adjunctive modalities (e.g., infrared warmth, PEMF) under guidance.
What to Expect
Many people describe temporary feelings of warmth and relaxation afterward. Mild, short-lived effects (e.g., skin warmth, lightheadedness) can occur. Not everyone is a candidate; we review medical history, medications, and contraindications and obtain informed consent before any session.
