Uw360 takes you into the minds of freediving world record holder Herbert Nisch and diving endurance world record holder Sean McGahern in this revealing interview piece
“The Deepest Man on Earth” with a No Limit freedive to 253m/831ft, Nisch has set 33 world records, across all of the freediving disciplines.
Underwater360: How has breaking records changed you?
Herbert Nisch: Breaking records made me understand that everything is possible in life. Not just in sports, but also in healing and in everyday life. Once you understand how your body functions, you can use this knowledge constantly.
After my last No Limit world record (253m/831ft) in 2012, I incurred severe decompression sickness. Its onset takes a while. About 15 minutes after the dive, while recompressing underwater on pure oxygen, I felt it was coming. Three hours later I was comatose in a hyperbaric hospital. The diagnosis was severe DCS, resulting in multiple brain strokes. The prognosis was that I would be a “wheelchairbound basket-case” for the rest of my life.
I was not going to accept that. And no matter how severe the limitations of my body and mind were, I was determined to snap out of it. Eventually I threw all (Western) medicine away and dismissed myself out of long-term care, and started my own healing and fitness regime. I used all the knowledge I had about my own body and mind to get well again. It was a long road and very challenging at times. I got myself out of that wheelchair, and got my brain back into shape as well. In the summer of 2014 I was deep freediving again, just to see how I would feel at depth. Underwater I feel as if nothing ever happened. On land I still have some challenges with balance and coordination sometimes. The doctors call it a “miracle”, but there is nothing miraculous about it. It is all about knowing and understanding yourself. Everyone can learn this. The miracle is the human body and mind itself.
With three world records, master of endurance McGahern has spent some incredible lengths of time underwater, but is about to undertake the most intense challenge of his life.
Underwater360: What are some of the challenges you’ve faced in your career as a record breaker?
I dropped out of school at the age of 14 as a result of being dyslexic, but that hasn’t stopped me from breaking three world records.
I’d broken the record for the Longest Open Warm Water Sea Dive in 2009, spending 27 hours 35 minutes underwater. Then, in 2011, I started training for a new Guinness World Record for the Longest Cold Water Open Sea Dive. But, shortly after entering the water, a storm of force five to six winds blew across the island, and forced us to abort the attempt one hour and 10 minutes short of the record.
I finally succeeded in 2012. Eleven hours and 30 minutes into the dive, I began to feel the cold. But by 11 hours and 45 minutes in the dive, I already knew that I was the new world record holder, and, even though I was aiming at 15 hours, the team and I agreed that I had endured. I emerged out of the 14°C water 12 hours and 34 minutes later, breaking the record that stood at 11 hours and 46 minutes.
In October 2013, I again broke the world record for the Longest Warm Water Scuba Dive, this time by spending 49 hours and 56 minutes underwater, in aid of the charity Inspire, which provides therapeutic, education and leisure services to disabled adults and children. Despite suddenly being hit by strong winds, currents, surge and metre-high waves only five hours into the dive, we accepted this as an even bigger challenge.
This year I’m training for the biggest dive of my life, in aid of shark awareness with Project Aware. I will try to spend 10 days in a shark tank at a depth of four metres – a feat that should break all previous records by a mile.
