TLDR: In 2007, Austrian free-diver Herbert Nitsch set the world record by diving unaided to a depth of 214 m (702 ft) in the "No Limits" discipline. His remarkable feat pushed the boundaries of human endurance and physiology, earning him the title of "The Deepest Man on Earth."
Herbert Nitsch is a name synonymous with extreme free-diving. In 2007, he accomplished what was once thought impossible: diving unaided to a depth of 214 m (702 ft). Free-diving, especially in the "No Limits" category, is one of the most dangerous and extreme sports in the world. It requires athletes to dive as deep as possible using a weighted sled for descent and rely on a buoyancy device or airbag to return to the surface.
Nitsch’s record-breaking dive took place off the coast of Spetses, Greece, during a carefully orchestrated attempt. The depth of 702 feet presents immense physiological challenges, including the risk of nitrogen narcosis, decompression sickness, and the crushing pressures of the deep ocean, which can easily collapse a diver’s lungs. But Nitsch was no ordinary athlete; his mental and physical preparation was meticulous, involving years of training in breath-holding techniques, meditation, and strengthening his body’s ability to withstand the immense pressure of deep dives.
During his 2007 dive, Nitsch descended rapidly using a weighted sled. Reaching the 702-foot mark was only half the challenge—the ascent had to be fast enough to avoid hypoxia (lack of oxygen) but slow enough to prevent decompression sickness, also known as "the bends." Herbert completed the dive in about 9 minutes, a testament to his control and precision.
Nitsch’s incredible dive didn’t come without consequences. In a later record attempt in 2012, he suffered severe decompression sickness after ascending too quickly, which resulted in multiple strokes. However, his 2007 feat remains one of the most awe-inspiring achievements in human endurance, setting a record that still stands today.
Herbert Nitsch’s accomplishment not only pushed the limits of what humans can achieve underwater but also demonstrated the resilience of the human body under extreme conditions. His dives continue to inspire new generations of free-divers who are drawn to the thrill and danger of exploring the ocean’s depths unaided.
