Korean Women Divers Adapt with Unique Traits to Brave Frigid Waters

Quick Summary

• Haenyeo Divers: A group of elderly women, averaging 70 years old, from Jeju Island, South Korea, dives deep underwater without oxygen masks to collect shellfish. They can hold their breath and dive for up to five hours in near-freezing temperatures due to lifelong training. Historically, the Haenyeo tradition focused only on women and has roots going back thousands of years.
• Training & Sustainability: Women typically start diving with their mothers at a young age and begin formal training by age fifteen. The Haenyeo are known for lasting practices-rotating resources based on seasons to allow marine regeneration.
• Shrinking Community: The current generation may be the last as younger people do not predominantly take up this tradition. In 1950, there were 30,000 divers; by 2003 this number had dropped to just 5,650 registered divers over the age of 50.
• Genetic Study Findings: Research compared genomes between Haenyeo divers (average age: 65) and non-divers from Jeju Island and mainland Korea. Key findings include:

– Residents of Jeju had genetic distinctions tied to cold tolerance and reduced blood pressure that aids resilience in extreme underwater conditions.- These adaptations help mitigate risks like hypothermia or pregnancy complications such as preeclampsia during diving.
– Haenyeo showed unique physiological responses (e.g., heart rate dropping sharply during dives), likely influenced by lifelong habits combined with genetic factors.

• Implications Beyond Diving: Genetic traits in residents may contribute to lower stroke mortality rates on Jeju Island overall. Understanding these adaptations could inform cardiovascular health solutions amidst challenges posed by climate change.

Indian Opinion Analysis

The remarkable story of South Korea’s “Haenyeo” offers insightful parallels for India’s cultural practices deeply rooted in sustainability and skill transfer through generations-a characteristic found across various coastal fishing traditions within India’s own communities like those in Kerala or Odisha.

The scientific finding linking genetic adaptations among the haenyeo underscores how generational cultural practices interact with physiology over time-highlighting human resilience at both biological and behavioral levels amidst harsh environments. This interplay invites reflection on India’s indigenous populations thriving under extreme environmental conditions such as those living along high altitudes (like Ladakh). Studying similar phenomena within India might serve practical applications beyond anthropology-from improved healthcare solutions targeting heart disease risk factors among certain demographics to redefining adaptive strategies against growing environmental stressors induced by climate change.

While India’s customary livelihoods face modernization pressures similar to that reducing participation among South Korea’s younger Haenyo generations-preserving knowledge repositories remains critical not just culturally but scientifically amid rapid globalization dynamics threatening ecological balance globally.

India shoudl expand research examining adaptive behaviors within traditional communities-a pathway blending robust conservation science alongside societal health benefits since proven knowledge systems often tackle modern problems innovatively yet resourcefully without external dependence.
