Genetics of Korea’s extreme divers could unlock chronic disease treatments

The Haenyeo of Jeju Island, known for their remarkable ability to dive without modern equipment, have evolved unique genetic adaptations that protect their cardiovascular health. A study reveals a specific genetic variant linked to stable blood pressure during diving, even after pregnancy or childbirth—a condition traditionally deadly. This adaptation may have arisen through natural selection over centuries and could offer insights into managing chronic diseases like hypertension by understanding how genes influence extreme conditions. Such findings highlight the potential of studying genetic adaptations in diverse populations to improve medical treatments and disease prevention strategies.
