The Haenyeo, a community of female divers on Jeju Island, South Korea, have developed unique genetic traits that allow them to dive for extended periods. These adaptations include lower blood pressure and enhanced tolerance to cold water, likely influenced by their generations of traditional diving practices. A recent genomic study indicates they have evolved specific characteristics, such as bradycardia, improving their diving capabilities. This remarkable evolution opens pathways for potential medical advancements, as understanding the Haenyeo's genetic superpowers may lead to innovative treatments for blood pressure and related conditions.
When anyone dives, the combination of holding your breath and submerging yourself in water triggers the mammalian dive reflex.
The Haenyeo are one of only two groups of people known to have, quite literally, evolved to dive.
