The HOCATT is a health improvement device with ozone therapy as its main modality, complemented by 7 other therapy modalities including steam sauna/hydrotherapy, oxygen therapy, far infrared, carbonic acid therapy, herbal/aromatherapy, photonic light and spectrum therapy, and electrotherapy. With each 25 to 30-minute session, clients receive scientifically proven detox and oxygenation, beauty and anti-aging benefits, athletic enhancement and an overall improvement of wellness and vitality. For the first 3-8 minutes of the session, carbonic acid (CA) and steam moisten the skin and enter through pores into lymph system. CA increases the uptake and delivery of oxygen at the cellular level. Blood vessels and capillaries dilate, increasing blood circulation up to 25%. Afterwards, the ozone cycle begins. When ozone reacts with the water from the steam, it creates H202 which aids in destroying bacterial and yeast/fungal infections.
