What happens to the body under water #Science #diving #underwater #documentary

How deep can humans actually go underwater, and what happens to the body along the way? At 10 meters, pressure doubles, your ears, squeeze, your chest, tightens, but almost anyone can do this. At 50 meters, everything changes. This is no longer casual diving. Only trained divers go here. Nitrogen begins to cloud the brain. Oxygen itself can turn toxic. Breathing stops being automatic. Every breath is controlled. At 150 meters, humans are no longer adapted. They are tolerated. Special gas mixtures are mandatory. Cold drains energy fast. One mistake here doesn't give you a second chance. And yet, one man went even deeper. In 2014, an Egyptian technical diver named Ahmed Gabar descended to 332 meters underwater. No submarine, no protective capsule, just tanks, gear, and years of discipline. At that depth, pressure crushes at 34 times normal force. Oxygen can trigger seizures. Nitrogen distorts reality. One wrong movement ends everything. Most of the dive wasn't going down. It was surviving the way back up. The descent took minutes. The return took over 12 hours. The deepest a human has ever gone. Reminder. Some places on Earth will never belong to us. They only let us visit.
