Under Pressure Hyperbarics loves the Octopus creature under the sea because of its ability to require more oxygen than other fish and mollusks. They require 4 times the normal amount of oxygen needed and have 3 hearts, 2 of which are dedicated to pump blood through the gills just for oxygen. Another cool fact is that Octopus use copper to transport oxygen unlike humans who use iron.

Hyperbaric Oxygen Therapy (HBOT) helps the body in many ways, especially FDA-approved specific medical conditions that work well as a treatment for the body. Hyperbaric is shown to reduce swelling and increase the amount of oxygen that goes directly into the blood stream, which in turn, helps tissue growth. HBOT promotes natural healing with great benefits such as wound healing and stem cell growth. Hyperbaric oxygen therapy has shown to improve clients quality of life in many sectors. Conditions such as head injuries, chronic fatigue, stroke, cerebral palsy, cancer, diabetes and more have responded favorably to HBOT in many studies and contentious real life use.
