The average person can hold their breath underwater for 30-60 seconds. What about registrants?
The world record for holding breath underwater belongs to Croatian Budimir Shobat. It took 24 minutes 33 seconds. But before diving into the water, he breathed pure oxygen.
A scientific study published in Cell in 2018 found that Bajo people (nomadic sailors) have special physiological properties that help them hold their breath better underwater. It turned out that these people had a DNA mutation that led to an enlarged spleen. This way, they have more oxygen in their blood.
The world record holder for breath-holding among mammals is Cuvier’s otter. Such a person was under water for 222 minutes. Also, sperm whales can stay under water for 90 minutes, and seals – 30 minutes. This is explained by the fact that these animals have a lot of myoglobin in their muscles, and they also have torpedo-like streamlines (so they spend less effort when swimming).
