The Genetic Secrets of Haenyeo: Diving into Adaptation

On Jeju Island in South Korea, the Haenyeo, or “sea women,” are remarkable elderly divers harvesting seafood at great depths without oxygen tanks. This tradition is fading, with most active divers in their 60s to 80s, and fewer young women learning the skill. Research led by Dr. Melissa Ilardo has found that Haenyeo possess unique genetic traits linked to blood pressure regulation, possibly aiding their diving endurance. Their adaptations demonstrate an interplay of genetics and years of training. As their numbers decline, understanding their biology may lead to advancements in treating hypertension, highlighting the significance of their cultural legacy.
