Static Apnea World Record — How Long Can a Human Hold Their Breath

The Current Static Apnea World Record

The static apnea world record stands at 24 minutes and 37 seconds. That number stopped me cold the first time I read it. I’d been dabbling in freediving for about two years at that point, proud of pushing past two minutes in the pool during training sessions with my local AIDA club, and then I saw 24 minutes and 37 seconds sitting there like a quiet challenge to everything I thought I understood about human capability.

Croatian freediver Budimir Šobat set that record on March 27, 2021, in Sisak, Croatia. The discipline is called static apnea — motionless breath holding, face submerged, no swimming, no movement. Just a human being and the water and whatever is happening inside their body. It’s the purest possible test. No fins, no depth, no current to fight. Just time.

The conditions matter in this sport. Static apnea records are performed in a pool, typically in shallow water, with safety divers and officials present. Šobat was breathing pure oxygen in the minutes before his attempt — a legal practice in record attempts under certain sanctioning bodies, which distinguishes these marks from the records set breathing only ambient air. His 24:37 was set under Guinness World Records documentation, with oxygen pre-breathing permitted. The AIDA World Championship record for static apnea without oxygen pre-loading is a different and separately contested mark, typically in the 23-minute range for top competitors. Both numbers are, frankly, surreal.

What makes static apnea records so compelling to follow — more than depth records or dynamic apnea — is that the number is pure. There’s no equipment variable. The water doesn’t change. It’s 24 minutes of a man lying still in a pool, and the story behind that stillness is one of the more extraordinary things happening in human athletic achievement right now.

How Budimir Šobat Set the Record

Budimir Šobat was born in 1950, which means he was 70 years old when he began making serious runs at the static apnea world record. Let that sit for a second. The man setting breath-hold records in his seventies, in a sport that demands exceptional cardiovascular efficiency and lung capacity, is itself worth an entire article.

Driven by a specific goal rather than a lifelong career in competitive freediving, Šobat came to the sport relatively late and pursued it with methodical obsession. He’s described his training as something close to a full-time occupation — multiple pool sessions per week, CO2 tolerance tables run on a schedule, and a disciplined pre-competition protocol refined over years of attempts. He didn’t stumble into this record. He engineered it.

The record attempt itself followed a structured pre-breathing protocol lasting roughly 30 minutes, during which Šobat breathed medical-grade oxygen through a mask. This saturates the blood with oxygen while reducing the body’s CO2 burden, extending the possible breath-hold window significantly. Observers described the attempt as almost meditative in appearance — an older man floating face-down, completely still, attended by safety divers positioned at intervals. At the 20-minute mark, most people watching said the atmosphere in the room had shifted to something they struggled to describe. Hushed. Charged.

He surfaced at 24 minutes and 37 seconds. His first words, reportedly, were calm.

What I find genuinely moving about Šobat’s story — and I’ve watched the record attempt footage more than once — is that it reframes the sport. Freediving gets associated with young, elite athletes. Greek island instructors with resting heart rates in the low 40s. Šobat is a retired man from Sisak who decided he wanted to do something remarkable and then did the work. He’s broken his own records multiple times. The 2021 mark was not his first.

Other Record Holders Worth Knowing

Before Šobat’s dominance, the name most associated with static apnea records was Stéphane Mifsud of France, who held the AIDA static apnea record at 11 minutes 35 seconds for years. Stig Åvall Severinsen of Denmark broke that. The records have been pushed and re-pushed across multiple governing bodies and rule sets, which creates some confusion for newcomers. If someone tells you the record is different from what you’ve read here, they’re probably citing a different sanctioning body or a different pre-breathing protocol category. Both can be correct.

The Science of Extreme Breath Holding

Probably should have opened with this section, honestly, because understanding what the body actually does during a 24-minute breath hold makes the record feel even more extraordinary rather than just abstractly impressive.

The first thing that happens when you submerge your face in cold water is the mammalian dive reflex. Heart rate drops — sometimes dramatically — within seconds. Blood vessels in the extremities constrict, shunting oxygenated blood toward the heart, lungs, and brain. This reflex is shared by all mammals and is more pronounced in water below about 21°C (70°F). Elite freedivers can drop their heart rate to 20 or 30 beats per minute during a breath hold. Some recorded cases show rates below 10 bpm. Your resting heart rate right now is probably sitting between 60 and 80.

The spleen also contracts during extended breath holds, releasing stored red blood cells into circulation. This is not something you consciously do. Your body does it automatically, and trained freedivers show more pronounced splenic contraction than untrained individuals — meaning the adaptation is real and trainable. Some researchers have called this the closest thing humans have to a biological oxygen tank.

The urge to breathe that most people feel within 30 to 60 seconds isn’t caused by a lack of oxygen. It’s triggered by rising CO2 levels. Your body detects carbon dioxide as the waste product of cellular respiration and sends increasingly urgent signals to breathe it out. Experienced freedivers train their tolerance to CO2 — they practice sitting with that discomfort, recognizing it, and not reacting to it. This is done through CO2 tables: structured breath-hold intervals where rest periods are progressively shortened while breath-hold times stay constant, forcing the body to adapt to higher CO2 loads.

Oxygen, meanwhile, does eventually run low. Late in a breath hold, oxygen partial pressure in the blood can drop to levels that would cause blackout with no warning — no feeling of faintness, no gradual dimming. Just unconsciousness. This is called shallow water blackout when it occurs near the surface, and it kills freedivers every year. The physiology is unforgiving.

What the Body Looks Like at 20 Minutes

At 20-plus minutes into a static apnea, elite competitors have described the experience as deeply strange. The diaphragm begins involuntary contractions — the body’s mechanical attempt to force a breath — which trained freedivers learn to endure rather than react to. Peripheral vision can narrow. Cognition slows. The body has entered a state of extreme metabolic suppression. Blood has been redistributed. The spleen has done its work. The athlete is, at a cellular level, running on reserves that most human beings never access.

The fact that Šobat did this for almost 25 minutes, in his 70s, is the kind of thing that makes sports scientists lean forward in their chairs.

Can Regular People Improve Their Breath Hold?

Yes. Meaningfully. Most untrained adults can hold their breath for somewhere between 30 seconds and 90 seconds before the discomfort becomes unbearable. After even basic CO2 tolerance training — two weeks of consistent practice — that number typically doubles or more. I went from 1 minute 20 seconds to just over 2 minutes in my first month of structured training before my first PADI Freediver course. That course, which cost me around $350 with pool sessions included, changed how I thought about breath work entirely.

The standard entry path into freediving for breath hold improvement is a recognized course from AIDA, PADI, or SSI. These organizations teach the physiology, the safety protocols, and the supervised pool skills needed to train responsibly. The PADI Freediver course typically covers static apnea, dynamic apnea (swimming underwater on one breath), and free immersion up to 20 meters. Courses run one to two days and require a pool and open water component.

The safety warning here is not a formality. Never practice static apnea alone. Hyperventilation before breath holds — a common mistake beginners make trying to extend their time — reduces CO2 without increasing oxygen, which accelerates the risk of unconscious blackout. People drown doing this in backyard pools every summer. The rule in freediving is absolute: one up, one down. Always a buddy. Always.

A Simple Starting Framework

• Practice breath holds on land first, lying on a couch or flat surface — never in water alone
• Use a basic CO2 table app (Apnea Trainer is free on iOS and Android) to structure sessions
• Start with a 2-minute rest, 1-minute hold, repeated six times — adjust from there
• Track your resting numbers weekly, not daily — progress is slow and nonlinear
• Take a certified course before attempting any underwater breath holding

The gap between an untrained person and someone who has taken a single weekend freediving course is enormous. The gap between that person and Budimir Šobat is something else entirely — years of deliberate work, exceptional physiology, and a particular kind of stubborn patience that most of us don’t have. But the record exists to pull at you. To make you wonder what’s actually in there, waiting.

Twenty-four minutes and thirty-seven seconds. Face down. Still.
