How The Bajau People Survive: They Spend Most Of Their Lives Underwater

Imagine spending all your day swimming in the sea, how would you survive?

Although they do not have citizenship, the Bajau people, whose number is estimated to be one million, are spread across the southern Philippines, Indonesia, and Malaysia.

They live in houseboats, moving across the South East Asian waterways from place to place and rarely setting foot on dry land.

A Bajau person may spend up to five hours a day underwater, where they have perfect control, often times, they are only with a speargun and hand-crafted wooden goggles.


1. They puncture their ears:To accommodate their freediving lifestyle and the extreme pressure of the water below, some Bajau people pierce their eardrums. They will experience dizziness and ear and nose bleeding if this is not done. despite the fact that this may cause ear damage as they get older.


2.Their diaphragms are longer:Their diaphragms stretch and their lung and abdominal walls become more flexible in order to live underwater.

3.Their spleens are long:The spleens of the Bajau people are twice as big as those of their neighbors, the Saluans.Spleens aren’t necessary for life, but they help the immune system and filter blood by removing damaged red blood cells and recycling iron. But the most important thing is that the spleen stores a lot of blood.

When mammals are in the water, their spleens contract, distributing the oxygen-rich reserve in their blood throughout the body. More oxygen is available to swimmers whose spleens are larger.


4.Organs receive more blood than the legs do:The mutant gene causes a diving response to peripheral vasoconstriction. The Bajau may be able to effectively tighten non-critical areas of their circulatory system thanks to their unique genetic makeup.

This basically means that while less blood is used in areas like the legs, more blood is transferred to vital organs like the heart, lungs, and brain, allowing for longer dives.

It is amazing to observe how a person’s body changes in response to their surroundings.
