who holds the record for longest time holding breath
Stig Severinsen Combining yoga and his knowledge of physiology in freediving, Severinsen became a record holder of four AIDA freediving world records. He achieved two Guinness World Records in 2010: in March that year he swam 236 feet (72 meters) under ice wearing only swimming trunks and goggles, exceeding Wim Hof's record of March 2000 by 47.6 feet (14.5 meters); and in April, after inhaling pure oxygen, he held his breath for 20 minutes and 10 seconds in a tank full of sharks at the Kattegat Centre in Grenaa.[3] In May 2012 he was awarded the record of "Longest time breath held voluntarily (male)" by Guinness World Records for holding his breath for 22 minutes;[4] this record was achieved in a tank at the London School of Diving with the water cooled to 30 °F (-1 °C).[5] In April 2013 in Qorlortoq Lake in east Greenland, he set two new world records for "longest swim underwater - breath held": 500 feet (152.4 meters) while wearing a wetsuit and monofin, taking 2 minutes, 11 seconds,[6][7][8] and the following day, 250 feet (76.2 meters) wearing only swimming trunks.[9][10] He announced that these would be his last record attempts and he would now concentrate on teaching.[2]
