Is there evidence for hyperbaric oxygen?

Hyperbaric oxygen therapy (HBOT) is considered an emerging treatment for traumatic brain injury (TBI). While Andrew Huberman acknowledges its use following a TBI, indicating its potential benefits, Peter Attia expresses skepticism about the broader claims surrounding HBOT. Specifically, Attia criticizes the quality of studies supporting some of the therapy’s claims, highlighting the lack of rigorous methodologies and control groups in much of the research. Despite not being harmful, the effectiveness and the claims of HBOT remain under debate and require more rigorous study to confirm its benefits 1.
