In 2010, Danish freediver Stig Severinsen jumped into a pool filled with sharks and held his breath for 20 minutes and 10 seconds, breaking the previous Guinness World Record for the longest time breath held voluntarily.
Two years later, the fearless Stig did it again, somehow breaking his own remarkable record by holding his breath for a staggering 22 minutes. If there's such a thing as a real-life Aquaman, it's this guy.
Severinsen – who has a Ph D in medicine and a master's degree in biology, is known for participating in the most extreme challenges, including swimming in freezing water.
Before setting his first breath holding world record, he swam 236 feet – about 72 meters (14.5 more meters than Wim Hof, the previous record holder), in the below-zero waters of the North Sea. After taking a few breaths of air, he dived feet first through a hole carved in the ice. As soon as he was in the water, he started swimming to the next hole wearing only in his signature blue Speedos.
The triangle-shaped hole was 72 meters away and there wasn't another escape route mid-way, which made the challenge extremely dangerous. After reaching his destination in just 96 seconds, the 40-year-old daredevil lingered in the freezing hole a little longer, as if to prove the cold didn't affect him very much.
