How deep do divers go?

In the 1950s, experts said that the human body could dive to a depth of only 100 meters. They claimed that deeper diving would cause fatal bodily injuries and permanent damage to the internal organs, questioning the diving safety in general. However, the divers proved them wrong. They  showed that a man can survive depths significantly greater than 100 meters.

What happens to our body while we are diving?

At the first 30 meters of depth, the lungs, which are full of air, force us to get out of the water, and at 33 m, they expel the rest of the air and shrink by half. Air pressure is getting bigger and bigger and divers can feel it in their head.

At a depth of about 40 meters, there is an area without gravity, which divers call ‘the door to the depth’. On this depth, the ocean no longer rejects us, but accepts us as a part of its own.

At 100 meters, the pressure is tripled. Heart rate still slows down, leaving the remaining oxygen for our body.

At depths of 100 meters with top scuba gear, some divers have a heart rate of only 14 beats per minute, which is very low if we know that the average heart rate in a healthy, adult human is between 60 and 90 per minute. This is why researchers used to think that 100 meters is the diving depth limit for humans.

Surprisingly, when we reach a depth of 300 meters, certain, rarely experienced processes by humans begin, including a more free blood, water and air flow.

What is the world diving depth record?

Currently, the scuba diving record is 332 meters of depth. It was set four years ago, in 2014, by an extraordinary diver Ahmed Gabr who loves to live adventurously and move the limits in diving. He describes the diving feeling as heaven on Earth.

What happens while we are coming out to the surface?

As the body approaches the surface, the water pressure has the opposite effects. The heart rate rises, the blood that has been trapped in the center of the body slowly begins to move towards the limbs, filling each particle of the body. The lungs are getting wider and filled with air.

Divers have proven that the human body cannot reach decompression while diving as we are automatically prepared for the oxygen-free state. We have enough of it in our organs to survive great depths. We were born to dive!
