Bajau tribe never sets foot on land; instead, they inhabit the azure waters that encircle the southern Philippines, Indonesia, and Malaysia

A genetic abnormality known as the “sea nomad gene” allows an amazing tribe of fish people known as Bajau to hold their breath underwater for 10 minutes in order to spear meals.

Larger spleens were created by the Bajau people of Southeast Asia so that they could store more oxygen in their blood for free diving.

The water tribe never sets foot on land; instead, they inhabit the azure waters that encircle the southern Philippines, Indonesia, and Malaysia.

They are called “sea gypsies” because of their well-known itinerant way of life.

These fishermen’s incredible diving skills make them appear like real-life Aquaman.

Because of their enlarged spleens, Bajau people can submerge up to 200 feet and stay submerged for up to 10 minutes.

Spoken like a fist, the spleen stores excess oxygen in the bloodstream like a biological “scuba tank” and is situated adjacent to the stomach.

Dr Ilardo of the University of Copenhaden spoke to BBC about, “The spleen is a reservoir for oxygenated red blood cells, so when it contracts, it gives you an oxygen boost.”

The spleen sizes of the community’s divers and non-divers are comparable, according to research by Dr Ilardo and her associates.

This might imply that the expansion is a result of evolution rather than just a result of diving.

It’s possible that the Bajau evolved a larger spleen in order to endure the prolonged, frequent dives they engaged in for thousands of years.

“They dive repeatedly for eight hours a day, spending about 60 per cent of their time underwater,” said Dr Ilardo.

These dives are only done with a weight belt and a wooden mask or goggles.

The sea nomads utilise their extraordinary abilities to catch supper, mostly fish, lobsters, and sea cucumbers.

The latter is utilised as an aphrodisiac as well as a medication.

The tribe is self-sufficient and survives by using traditional marine hunting methods.

They trade excess fish with islanders to obtain necessities that they are unable to locate in the ocean.

The Bajau choose to live in homemade boats and stilted wooden cottages than conventional homes.

Additionally, rather than attending school to study arithmetic or history, the youngsters of the tribe learn how to capture fish using a net.

 

Meet the Bajau Tribals: Masters of Breath-Holding Underwater

The Bajau people, often referred to as “Sea Nomads,” are indigenous to Southeast Asia, particularly the waters around the Philippines, Malaysia, and Indonesia. Renowned for their remarkable ability to hold their breath for extended periods while diving, some Bajau divers can stay underwater for up to 10 minutes. This extraordinary capability has intrigued scientists and fascinated people around the world. But how do they do it?

1. Genetic Adaptations

• Natural Selection: Over generations, the Bajau have developed genetic adaptations that enhance their ability to free dive. A study published in the journal Cell found that Bajau individuals have larger spleens than their non-diving counterparts.
• Spleen Size: The spleen acts as a reservoir of oxygenated red blood cells. When the body is deprived of oxygen, such as during a deep dive, the spleen contracts and releases these cells into the bloodstream, prolonging the time a person can stay underwater.

2. Physiological Traits

• Bradycardia: The Bajau exhibit a pronounced diving response known as bradycardia, where the heart rate slows significantly to conserve oxygen.
• Peripheral Vasoconstriction: This response also includes peripheral vasoconstriction, which reduces blood flow to extremities and preserves oxygen for vital organs like the heart and brain.

3. Training and Lifestyle

• Early Training: Bajau children start diving and swimming at a young age, training their bodies and minds for breath-hold diving. This early exposure helps them develop exceptional underwater skills.
• Daily Practice: The Bajau’s lifestyle revolves around the sea. They spend hours each day diving for fish, sea cucumbers, and other marine resources, continuously honing their breath-holding abilities.
• Diet: Their diet, rich in seafood, provides essential nutrients that support their high level of physical activity and endurance.

4. Techniques and Methods

• Hyperventilation: Before diving, Bajau divers often practice hyperventilation, which involves taking rapid, deep breaths to increase oxygen levels and decrease carbon dioxide in the blood.
• Relaxation: Maintaining a state of calm and relaxation is crucial. The Bajau are adept at staying relaxed underwater, conserving oxygen and reducing metabolic rates.

5. Cultural Practices

• Spiritual Beliefs: Many Bajau believe in the protective powers of the sea and incorporate spiritual practices that foster a deep connection with the ocean.
• Traditional Knowledge: Passed down through generations, traditional knowledge about diving techniques and safety measures ensures that new divers learn the best practices from experienced elders.

Conclusion

The Bajau people’s ability to hold their breath for extended periods while diving is a combination of genetic adaptations, physiological traits, rigorous training, and cultural practices. Their unique lifestyle, centered around the sea, has allowed them to develop and maintain these extraordinary skills. As science continues to study the Bajau, we gain deeper insights into the human body’s potential and the fascinating ways in which humans can adapt to their environments
