The Man Who Held His Breath for 24 Minutes: Inside the Extraordinary World of Budimir Šobat.

In the quiet, chlorinated air of a swimming pool in Sisak, Croatia, the boundary between human capability and biological impossibility was not just tested; it was shattered. Budimir “Buda” Šobat, a man whose physical presence suggests the rugged build of a lifelong athlete rather than the ethereal grace often associated with elite divers, lay motionless on the water’s surface. For 24 minutes and 37.36 seconds, his lungs remained static, his heart rate plummeted to a rhythmic crawl, and his consciousness drifted into a realm few humans will ever visit. This feat, which earned him a Guinness World Record, is more than a display of lung capacity; it is a profound testament to the intersection of physiological adaptation, psychological resilience, and the transformative power of a father’s love.

To understand how a human being can survive for nearly a quarter of an hour without taking a single breath, one must first look at the science of the mammalian dive reflex. This evolutionary inheritance, shared with whales, seals, and dolphins, is a complex set of physiological responses that override the body’s homeostatic reflexes to preserve life in the absence of oxygen. When a person’s face is submerged in water, sensors in the nasal cavity and the face trigger the trigeminal nerve, sending a signal to the brain to initiate an immediate survival protocol. The heart rate slows—a phenomenon known as bradycardia—by as much as 25 to 50 percent in trained individuals. Concurrently, peripheral vasoconstriction begins, narrowing the blood vessels in the limbs to shunt oxygen-rich blood toward the brain and heart, the body’s most critical organs.

However, Šobat’s record-breaking performance utilized an additional advantage: the pre-breathing of pure oxygen. In the world of competitive freediving, there is a distinct line between "static apnea" (performed on a single breath of ambient air) and "O2-assisted static apnea." While the record for the former stands at roughly 11 minutes and 54 seconds, held by Branko Petrović, the use of 100 percent oxygen allows the body to saturate its tissues and bloodstream far beyond normal levels. By flushing the nitrogen out of his system and replacing it with a massive reservoir of oxygen, Šobat effectively turned his body into a biological scuba tank. Yet, even with this advantage, the 24-minute mark remains a terrifying threshold. At this duration, the primary challenge is no longer just the lack of oxygen, but the toxic buildup of carbon dioxide (CO2).

Carbon dioxide is the true master of the breath-hold. It is not the absence of oxygen that creates the agonizing "urge to breathe," but rather the rising acidity of the blood as CO2 levels climb. This acidity triggers the chemoreceptors in the carotid arteries and the brainstem, which scream at the diaphragm to contract. For an average person, these contractions begin after sixty seconds. For Šobat, they are a familiar, albeit painful, companion. He has spent years conditioning his brain to ignore these signals, essentially decoupling the involuntary physical reflex from the conscious mind. This requires a level of mental discipline that writer Sean Williams, who profiled Šobat for Outside, likens to a "superpower" akin to those found in the X-Men comics. Šobat enters a state of profound stillness, a meditative trance where the external world ceases to exist and his internal world narrows to a single, focused point of endurance.

The path to this record was not an obvious one for Šobat. Unlike many elite freedivers who begin their journey in their youth, Šobat was a late bloomer in the sport. A former bodybuilder, his musculature initially seemed like a disadvantage; muscle tissue is metabolically expensive, requiring significant amounts of oxygen to maintain. Most freedivers aim for a lean, almost wiry frame to minimize oxygen consumption. However, Šobat’s background in bodybuilding provided him with a different kind of edge: an intimate knowledge of physical suffering and a disciplined approach to training. He began freediving in his 40s, eventually finding his niche in static apnea under the mentorship of Ivan Drviš, a renowned coach in the Croatian diving community.

Yet, the physiological mechanics and the rigorous training schedules only tell half the story. The true engine behind Budimir Šobat’s record-breaking attempts is his daughter, Saša. Now in her 20s, Saša lives with cerebral palsy, autism, and a history of seizures. Her condition requires constant, 24-hour care—a responsibility that Šobat and his wife have embraced with tireless devotion. In many ways, Šobat views his daughter’s daily struggle as the ultimate inspiration for his own. He often remarks that the pain he feels during the final minutes of a 24-minute breath-hold is nothing compared to the challenges Saša faces every day of her life.

This emotional connection transformed his athletic pursuit into a humanitarian mission. Šobat’s record attempts are frequently organized as fundraising events for the "Room of Miracles" (Soba Čuda), a therapeutic center in Sisak dedicated to helping children with disabilities. By pushing his body to the literal brink of death, Šobat draws international attention to the needs of these children, using his "superpower" to provide resources for those who cannot fight for themselves. The psychological weight of this mission provides him with a reservoir of strength that transcends mere physical training. When the CO2 levels in his blood reach critical levels and his diaphragm begins to spasm uncontrollably, he thinks of Saša. This mental anchoring allows him to endure the "dark zone" of the breath-hold, where the body’s survival instincts are at their most frantic.

The risks associated with such extreme apnea are significant. Beyond the immediate danger of a "shallow water blackout"—a loss of consciousness caused by a rapid drop in oxygen tension—there are long-term concerns regarding neurological health. Critics and some medical professionals have questioned the safety of holding one’s breath for such extended periods, citing potential micro-insults to the brain and the risk of cardiac arrhythmias. However, Šobat undergoes regular medical screenings, and his performances are monitored by doctors and safety divers. His ability to recover almost instantly after a 24-minute submersion—surfacing with a smile and a clear "I am okay" signal—continues to baffle and fascinate the medical community.

Expert perspectives on Šobat’s feat often highlight the "spleen effect." In response to the extreme stress of apnea, the human spleen can contract, releasing a surge of oxygen-rich red blood cells into the circulation. This acts as a natural blood booster, a physiological "second wind" that can increase an athlete’s oxygen-carrying capacity by up to 10 percent. In Šobat, this reflex appears to be exceptionally well-developed. Furthermore, his training involves "hypercapnic" sessions—drills designed to increase his tolerance to high CO2—and "hypoxic" sessions designed to train his brain to function at low O2 levels.

The broader context of Šobat’s achievement places him in a lineage of "aquatic pioneers" who have consistently redefined the limits of human biology. From the legendary Jacques Mayol, the first man to dive to 100 meters, to contemporary icons like Natalia Molchanova, the history of freediving is a history of humans proving scientists wrong. Decades ago, physiologists predicted that the human chest would collapse under the pressure of 50 meters of depth; today, divers reach over 130 meters on a single breath. Similarly, the 24-minute barrier was once thought to be the exclusive domain of marine mammals. Šobat has proven that the human mind, when properly focused and motivated by a cause greater than oneself, can command the body to perform the impossible.

In the Outside Podcast Long Read, the narrative delves deep into the silence of the water. It explores the "complicated world" Šobat inhabits—a world where the silence of a breath-hold mirrors the silent struggles of his daughter’s condition. The story is not just about a record in a book; it is about the philosophy of stillness. In an age of constant distraction and noise, Šobat’s 24 minutes of silence represent a radical form of presence. To hold one’s breath for that long is to enter a state of total biological economy, where every unnecessary thought and every superfluous movement is stripped away.

As Šobat approaches his 60s, he remains a figure of intense curiosity. His story challenges our understanding of aging, showing that the peak of human endurance may not always be reserved for the young. It also serves as a poignant reminder of the power of the human spirit to find meaning in suffering. Every second Šobat spends underwater is a second spent in solidarity with his daughter. He is the man who held his breath for 24 minutes, but more importantly, he is a father who found a way to turn his own physical struggle into a beacon of hope for others.

The legacy of Budimir Šobat will likely be measured not just in the minutes and seconds recorded by a stopwatch, but in the lives touched by the "Room of Miracles" and the expanded understanding of what the human body can endure. As he continues to train and inspire, he remains a living bridge between the world of elite athletics and the quiet, everyday heroism of caregiving. In the end, his 24-minute record is a reminder that while our biological limits are real, they are often much further than we imagine—and sometimes, it takes a "superpower" born of love to reach them.
