Breatheology – The Art Of Conscious Breathing” (10 Languages)


Severinsen has a degree in biology and a Ph.D. in medicine. He began experimenting with holding his breath as a child at the bottom of his parents’ pool. He started swimming at the age of 6 and was awarded National Champion four years in a row at 9, 10, 11 and 12. From 1993 – 2003 he played underwater rugby and was a member of the Danish national team. During university studies in Barcelona, Spain in 1998 – 1999, he played underwater hockey on the Spanish national team. A fascination with long breath holds underwater drew him to the world of free diving. In 2010 he founded Breatheology – an online platform teaching optimal health and performance via breathing, breath holding, and mental training techniques.

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 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 Center in Grenaa, Denmark, becoming the first human on the Planet to ever break the magical 20-minute glass-barrier. 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. In April 2013, in Oorlotoq Lake in East Greenland, he set two new world records for “Longest swim under ice – breath held”: 500 feet (152.4 meters) while wearing a wetsuit and monofin, taking 2 minutes, 11 seconds, and the following day, 250 feet (76.2 meters) wearing only swimming trunks. He announced this would be his last record attempts and he would now concentrate on teaching.
