Deep Freediving Study Reveals Human Physiological Responses to Extreme Stress

Researchers from the University of Auckland conducted the deepest physiological study of freedivers, collecting arterial blood samples at depths up to 80 meters. This pioneering work, recognized by the American Physiological Society, provides rare insights into how the human body responds to extreme breath-hold diving. The findings help explain phenomena like blackouts and advance understanding of human physiology under stress.
