HBOT exposes our bodies to elevated levels of oxygen-rich air. Since more oxygen is being spread throughout the circulatory system and tissues within the body, it stimulates the body’s healing response system. In addition, the oxygen helps reduce anxiety levels and stress levels due to heightened levels of oxygen within the brain and creates a calming effect. Stress and anxiety slowly start to become less intense emotions and are replaced by a relaxed state of mind.

​

For instance, HBOT has been used by military veterans experiencing post-traumatic stress disorder (PTSD). Those that receive regular HBOT noticed many of the symptoms associated with PTSD, like depression and anxiety became less frequent and severe, allowing them to better integrate back into private life and society.
