Hyperbaric oxygen therapy (HBOT) strengthens both the innate immune system and the adaptive immune system. By doing so, the body is better prepared to eliminate pathogens before they can cause serious damage. HBOT improves the immune system through two main mechanisms. Firstly, HBOT increases the activity and efficacy of white blood cells (WBCs)(2, 3). WBCs are directly responsible for eliminating pathogens, so enhancing WBC activation results in a more effective immune response.
Secondly, HBOT floods tissues with oxygen, creating an environment in which harmful anaerobic bacteria (bacteria that live in low/no oxygen) cannot survive(4). Together, these mechanisms make HBOT an effective therapy for strengthening the immune system and decreasing risk of infection and pathogen-driven disease.
