Can you imagine holding your breath for the entire length of a sitcom? On June 14, 2025, Croatian freediver Vitomir Maričić did just that and more. He set a new world record by holding his breath underwater for an incredible 29 minutes and 3.07 seconds. This wasn’t just inching past the old record; he smashed it by a full five minutes, doing something that sounds like it’s straight out of a comic book. This amazing feat shows us what the human body is truly capable of and how powerful the mind can be when it comes to ignoring our most basic instincts.

Defying Human Limits: The 29-Minute Breath-Hold
The record was broken in a controlled, 3-meter-deep swimming pool at a hotel in Opatija, Croatia. This wasn’t some casual dip; it was a serious event with official judges from the International Association for Development of Apnea (AIDA) and a full support team monitoring Maričić’s every second to ensure his safety. After taking his final breaths of pure oxygen, he assumed a completely motionless, face-down position on the water’s surface, supported by pool noodles to minimize any energy use. For nearly half an hour, he was perfectly still. The most remarkable part might have been his recovery. When he finally surfaced, he was calm and composed, not gasping for air like you’d expect. It was a clear sign of the incredible level of physical and mental conditioning he had achieved to make the impossible look almost routine.
The Body’s Hidden Superpowers
How could someone hold their breath for nearly half an hour? It all kicks off with a cool trick that basically turns the body into a human oxygen tank. For up to 30 minutes before the dive, the athlete breathes 100% pure oxygen. The air we breathe every day is only about 21% oxygen, so this “pre-loading” technique flushes all the useless nitrogen out of the lungs and crams every cell in the body with about five times the normal amount of O₂.
This huge oxygen boost does something else that’s super important: it hits the snooze button on your body’s “gotta breathe” alarm. That desperate, panicky feeling you get when you hold your breath doesn’t actually come from a lack of oxygen. It’s from a buildup of carbon dioxide (CO₂) in your blood. This CO₂ makes your blood a bit more acidic, and tiny sensors in your brain start yelling, “Breathe now.” By starting with a ton of extra oxygen, it takes way longer for CO₂ to build up to panic levels, which makes the first few minutes of the hold feel surprisingly chill.
Once underwater, your body’s ancient programming takes over and flips on a set of amazing survival reflexes called the Mammalian Diving Reflex. Yep, we have this in common with dolphins and seals. The second water touches your face, your body instantly goes into oxygen-saver mode. Your heart rate slows way down, sometimes to as low as 20 beats per minute—it’s like an emergency brake that slashes energy use.
At the same time, your body starts rerouting power. Blood vessels in your arms and legs squeeze shut, pushing all the oxygen-rich blood away from your limbs and toward the two most vital organs that need it most: your brain and your heart. Your spleen even gets in on the action, contracting to release its personal stash of extra red blood cells into your bloodstream. It’s like having a small, built-in scuba tank.
Training to Be a Human Submarine
You’re not born with this kind of control, that’s for sure. It’s the result of years of really specific training that slowly teaches your body’s alarms to quiet down. A huge part of the physical work is just learning to deal with the super uncomfortable feeling of high CO₂ levels, which eventually makes your diaphragm start spasming like crazy.
To do this, freedivers use special routines called “tables.” A CO₂ table might mean holding your breath for two minutes, resting for two, and then doing it again and again. Each time, the rest period gets shorter. This forces the body to get used to running while flooded with CO₂, training the mind to stay calm when your body starts to shake and beg for air during what they call the “struggle phase.”
But the mental training? That’s what truly separates the elite from the rest. Athletes use meditation and body-scanning tricks to get completely and totally relaxed before they even start the hold. Any little bit of stress or muscle tension is an oxygen thief. The goal is to be perfectly still, turning your body’s “engine” down to a slow, silent idle.
A Tale of Two Divers: What Drives a Champion?
The last two guys to hold this record, Vitomir Maričić and Budimir Šobat, show that you can be driven to do this for totally different reasons. Maričić is a full-on pro who’s a bit of a science geek about the sport, with a background in physics and kinesiology. For him, breaking the record was a personal goal and a way to shout out his passion for protecting the oceans.
Budimir Šobat’s story is another thing entirely. He got into freediving at 48, an age when most athletes are kicking back and relaxing. His motivation was his daughter, Saša, who lives with autism, cerebral palsy, and epilepsy. He turned his diving into a platform to raise awareness and money for families just like his. A father’s love fueled all that intense training.
But Šobat found out something weird. Even though his daughter was the “why” that got him through all the training, thinking about her during the actual breath-hold made things tougher. The strong emotions jacked up his heart rate and burned through his oxygen. To pull it off, he had to find a state of an “empty mind.” It just goes to show that while a big purpose gets you to the starting line, a calm, clear head is what you need to finish the race.
Where the Abyss Stares Back
These feats are incredible, but they happen right on the edge of human safety. The biggest danger is a “hypoxic blackout”—basically, passing out because your brain runs out of gas. It can happen without any warning, which is why the number one rule in freediving is to never, ever train alone. A safety diver is always right there, watching for the smallest sign of trouble.
A big warning sign is something they call a “samba,” where the body starts to shake uncontrollably as the brain falters. It’s a scary signal that the diver has pushed way too far. Researchers have also found that these crazy-long breath-holds cause a temporary spike in a protein that’s normally locked up in the brain. When it leaks out into the blood, it’s a sign the brain is under some serious stress. The divers are fine afterward, but it shows just how close they get to their absolute physical limits.
Mastery of the Self
Essentially, this is not merely a record in sport, but also a deep journey into the mind. To accomplish this, a diver must learn to mute the loudest alarm in their body, the frantic cry for air. It requires deep focus, almost like deep meditation, to sit with the constricting panic without letting it overwhelm them. By pausing something most of us do without thinking, the diver’s attention is directed inward, and they have to find a calm space in the middle of their own maelstrom.
The true victory here is not about overcoming the body’s need for air, but getting control of the mind’s panicked response to not having air. It is a potent lesson about we can learn to be face our greatest fears not through force but by being still. In that truly still space, you not only learn how much your body can withstand, but how strong a still mind can be.
