The World Record of ‘longest time to hold breath under water’ was achieved by Tom Sietas from Germany.

Tom Sietas set this record by holding his breath under water for 22.22 minutes. Sietas has a lung capacity 20 percent larger than an average person his size. Sietas was dropped into a clear tank containing water cooled to 41 degrees Fahrenheit to help him relax and calm his body. He normally preps for an event by not eating for at least five hours prior in an effort to slow his metabolism and then filling his lungs with pure oxygen.
