Psychophysiological reactions in humans during an open sea dive to 500 m with a hydrogen-helium-oxygen mixture

The Deep Dive: How Humans React to Extreme Underwater Pressure

A 1994 study explored the psychological and physiological reactions of divers during an open sea dive to 500 meters using a hydrogen-helium-oxygen mixture. The research found that the gas mixture helped reduce the severity of High-Pressure Nervous Syndrome symptoms. The study's findings have implications for people who work or play in high-pressure environments.
