韩国济州岛海女自由潜水的健康启示
On Jeju Island, hundreds of women in their 60s, 70s, and even 80s slip into the cold sea every morning without scuba gear. They are haenyeo, or female free-divers, who have harvested shellfish from the ocean floor for generations. Their remarkable longevity and vitality have attracted scientists eager to understand how extreme physical activity and strong community bonds shape human health.
Free-diving requires holding one’s breath for up to two minutes while swimming against currents. This repeated breath-holding acts as a natural form of interval training, improving cardiovascular efficiency and lung capacity. Studies suggest that haenyeo have lower resting heart rates and better blood oxygenation than typical women their age, offering a living example of how intense but controlled exercise can slow some effects of aging.
