How Korea's Haenyeo developed extraordinary cold resistance that lets them dive into near-freezing seas without oxygen tanks, even in their 70s

Image: Kyoto Journal Why the Haenyeo can swim in ice-cold seawater while most people quickly lose body heat How scientists tested whether Haenyeo are biologically better adapted to cold than other people Why two heat-producing hormones make the Haenyeo exceptionally resistant to freezing water How decades of breath-hold diving changed the Haenyeo's bodies to conserve heat Why the Haenyeo remain one of the world's most extraordinary examples of human adaptation Why scientists believe the Haenyeo still have much to teach us about surviving extreme environments
