Jeju’s Female Divers Possess a Genetic Advantage

Jeju Island’s famed female free divers, known as Haenyeo, possess remarkable physiological adaptations that appear to be rooted in their genetics, according to new research. These women, who traditionally free-dive to collect seafood, exhibit significantly enhanced cold tolerance and unique blood pressure responses that allow them to withstand prolonged exposure to frigid waters. Researchers describe these adaptations as akin to a “superpower,” enabling dives lasting several minutes without specialized equipment. The findings suggest a genetic component contributing to the Haenyeo’s exceptional diving abilities, potentially offering insights into human adaptation to extreme environments. It’s a compelling example of how cultural practice and natural selection can intertwine, resulting in a truly extraordinary skillset passed down through generations. The Haenyeo represent not just a unique cultural heritage, but a fascinating case study for understanding the limits of human physiological resilience and adaptation – a testament to the power of both nature and nurture.
