A short, curated list of authoritative places to verify what's on this site and read further — the professional bodies, the regulator, the journals that actually published these trials, and the databases where the whole literature lives.
Drowning is one of the injuries that starves a brain of oxygen — the same downstream damage HBOT is designed to act on. These sources give the public-health context.
A word of care. These links point to independent bodies and journals — they don't endorse this site, and some describe HBOT's brain uses as still under study. That's the honest picture, and exactly why we point you to them: read the primary sources and decide for yourself.
