flag Breath-hold diving can cause sudden, fatal blackouts even in healthy swimmers, experts warn.

flag A new report by Edinburgh University scientists, including professors Andrew Baker and Hugh Montgomery, warns that breath-hold diving can cause sudden, fatal shallow water or hypoxic blackouts even in young, healthy swimmers. flag Inspired by personal tragedies—Baker’s son nearly died after hyperventilating before diving, and Montgomery’s son died while snorkeling despite being experienced—the report explains that hyperventilation lowers carbon dioxide, delaying the urge to breathe and increasing blackout risk. flag The authors urge supervised breath-hold sessions, swimming with a partner, and equipping lifeguards with rescue tools and defibrillators, emphasizing that no one is immune regardless of fitness or skill.
