Hyperbaric oxygen therapy (HBOT) is a method in which a person breathes pure oxygen inside a pressurized chamber with a higher atmospheric pressure than normal. The increased pressure allows significantly more oxygen to be absorbed by the body and dissolved directly into the blood plasma, not only transported by red blood cells.

This enhanced oxygen availability improves tissue oxygenation, even in areas with reduced circulation. It may support faster healing, reduce inflammation, strengthen the immune system, and help the body recover from injury or physical stress. The treatment creates controlled, short-term biological stress signals that activate important cellular processes, such as stem cell activation, improved cellular function, and the selective removal of aging (senescent) cells.

HBOT has also gained attention for its broader health benefits. It is increasingly used for recovery in elite athletes, support for age-related conditions, and as part of modern longevity and health optimization programs.
