Imagine diving into 10°C water…
Without oxygen tanks…
For five hours a day.
For the women known as the Haenyeo of South Korea, that’s just another day at work.

For generations, these legendary divers from Jeju Island have harvested abalone, sea urchins, and shellfish using nothing but a single breath.
Many continue diving well into their 70s…
And some even kept diving while pregnant.

Scientists now believe their incredible abilities aren’t just the result of training.
A recent study found that people from Jeju carry genetic traits linked to better cold tolerance and healthier blood pressure, which may help them survive repeated dives in freezing water.

Their bodies have adapted in other ways too.
During dives, their heart rate drops dramatically, conserving oxygen and allowing them to stay underwater much longer than the average person.
Researchers describe it as one of the clearest examples of how humans can adapt to extreme environments over generations.

But this extraordinary tradition is disappearing.
Most Haenyeo today are around 70 years old, and very few young people are choosing to follow in their footsteps.
A centuries-old way of life…
Could soon exist only in history books.
