Many therapies. One quiet session.
HOCATT stands for Hyperthermic Ozone and Carbonic Acid Transdermal Technology. The name is a mouthful. The experience is simple: you sit in a warm pod and relax.
HOCATT (Hyperthermic Ozone and Carbonic Acid Transdermal Technology) is a warm pod that combines several technologies, including gentle heat and ozone, in one session, which is why people often call it an ozone sauna. Exhale Wellness offers HOCATT at 3338 Tyrone Blvd N, St. Petersburg, for guests across Tampa Bay. Your head stays outside the chamber.

Know before you go
HOCATT stands for Hyperthermic Ozone and Carbonic Acid Transdermal Technology. It is a seated steam cabinet that layers several features into one session. The maker lists steam, carbon dioxide, ozone, far infrared, PEMF, microcurrent, light and essential oils carried in the steam. At Exhale, your head stays outside the chamber while your body sits in the warmth. Many people simply call it an ozone sauna.
According to the maker, the chamber is warmed before you sit down. Carbon dioxide is added for the first few minutes, then ozone mixes with the steam for the rest of the session. When the time is up, a built in destructor runs for about 40 seconds to clear the ozone before the door opens. A session at Exhale is 30 minutes and is listed at $125.
Research on HOCATT itself is limited, and we do not know of good clinical trials on the device. The maker states it is not a medical device and has not been evaluated by the FDA. The FDA describes ozone as a toxic gas with no known useful medical use. Studies on regular sauna heat are mostly small. So think of HOCATT as a warm, quiet wellness experience, not a medical treatment.
Simple instructions are sent ahead of your appointment, and there is a short check in before your first session. The maker says sessions are usually set to your comfort, and many people start at gentler settings. If you feel pain or discomfort, tell us and the session can stop. Afterward, rest, rehydrate and take your time. You are welcome to stay for tea.
