![]() ![]() The International Association for the Development of Apnea, which records all freediving world records, does not allow the use of pure oxygen before a static apnea attempt. Prior to the attempt, she hyperventilated with oxygen for 24 minutes. The women's record is 18 minutes, 32.59 seconds, set by Brazillian Karoline Meyer in 2009. ![]() ![]() In 2012, German freediver Tom Sietas held his breath underwater for 22 minutes and 22 seconds, besting Dane Stig Severinsen's previous Guinness record by 22 seconds. Current Breath Holding World RecordsĮditor’s update: On March 27, 2021, Budimir Sobat of Croatia set a new world record of 24 minutes 37 seconds. Boosting oxygen stores, on the other hand, buys time before oxygen levels fall too low, which leads to brain and tissue damage. This practice, Discovery News reports, helps the body expel carbon dioxide, buying time before carbon dioxide levels become toxic. The Guinness Book of World Records allows divers to hyperventilate for up to 30 minutes with pure oxygen before they submerge for their record attempt. The event in question-holding one's breath underwater for as long as possible without moving-is officially called "static apnea," and there are two ways static apnea records are kept: for dives performed after breathing in pure oxygen, and for dives performed without pure oxygen. But professional divers can reduce theirs by more than 50 percent. The pulse rate in an untrained diver, the Daily Mail says, will decrease 10 to 30 percent when underwater. This article originally appeared on OutsideĪs the Daily Mail explains, humans set breath-holding records in water because they "can hold their breath twice as long underwater as they can on land.” The reason: the "diving reflex," in which the body slows its heart rate and metabolism in order to conserve oxygen and energy when submerged in cold water. ![]()
