What Is Ozone Therapy? A Complete Guide to the HOCATT Sauna
NJOY Clinical Team
February 1, 2026
The HOCATT sauna delivers 10 therapies in one 30-minute session. Here is everything you need to know about ozone therapy and why it is becoming a wellness essential.
Ozone Therapy Is Not New — But It Is Having a Moment
Ozone therapy has been used in clinical medicine for over a century, primarily in Europe. What is new is the accessibility. The HOCATT (Hyperthermic Ozone and Carbonic Acid Transdermal Technology) sauna brings medical-grade ozone therapy into a single, comfortable, 30-minute wellness experience — no needles required.
At NJOY, our HOCATT is one of our most popular treatments, and for good reason. It combines 10 distinct therapies into one session: ozone, carbonic acid, far infrared, electrotherapy, photon light, aromatherapy, pure oxygen breathing, and more.
How Does the HOCATT Work?
You sit inside the chamber with your head outside (so you are breathing room air, not ozone). The chamber fills with steam infused with ozone and carbonic acid. Your pores open, allowing ozone to be absorbed transdermally — through your skin — while far infrared energy heats you from the inside out.
The result is a deep, systemic detox that works at the cellular level. Ozone increases oxygen delivery to your tissues, supports your immune system, and helps neutralize pathogens, heavy metals, and chemical toxins.
Who Benefits Most from the HOCATT?
Chronic Fatigue and Low Energy
If you are constantly exhausted despite adequate sleep, ozone therapy can help improve mitochondrial function — the energy factories in your cells. Many clients report a noticeable energy boost after just one session.
Frequent Illness or Weakened Immunity
Ozone has powerful antimicrobial properties. Regular sessions can strengthen your immune response and reduce the frequency and severity of colds and infections.
Joint Pain and Inflammation
The combination of far infrared, electrotherapy, and ozone creates a powerful anti-inflammatory effect. Clients with arthritis, fibromyalgia, and chronic pain often find significant relief.
Athletes and Active Individuals
Post-workout HOCATT sessions accelerate recovery by reducing lactic acid buildup, improving circulation, and delivering oxygen to fatigued muscles.
What Does a Session Feel Like?
Most clients describe it as deeply relaxing — like a warm, spa-like steam session. You will feel warmth building gradually, and may notice a pleasant tingling as the carbonic acid dilates your blood vessels. The 30 minutes pass quickly, and many clients feel energized and clear-headed afterward.
