A dilapidated farmhouse in the Polish countryside creaks and groans on its foundation as six men hyperventilate inside one of its frigid rooms. The windows are caked with frost and snow piles up outside the front door. Wim Hof surveys his students with stern blue eyes as he counts their breaths. They are lying in sleeping bags and covered in blankets. Every breath they expel appears as a tiny puff of mist as the heat of their bodies crystallizes in the near-arctic air. When the students are bleached white from exhaustion, Hof commands them to let all the air out of their lungs and hold their breath until their bodies shake and shudder. I exhale all my breath into the frigid air.
“Fainting is okay,” he says. “It just means you went deep.”
Hof is one of the world’s most recognized extremophiles. In 2007 he made headlines around the world when he attempted to summit Mount Everest wearing nothing but spandex shorts and hiking boots. He has run barefoot marathons in the arctic circle and submerged his entire body beneath the ice for almost two hours. Every feat defies the boundaries of what medical science says is possible. Hof believes he is much more than a stuntman performing tricks; he thinks he has stumbled on hidden evolutionary potential locked inside every human body.
With my lungs empty and my head dizzy from hyperventilation, I note the stopwatch on my iPad as it slowly ticks by the seconds. At 30 seconds I want to let go and feel the cool air rush inside, but I hold on.
Participants have come from across Europe and America for this seven-day training program aimed at extending control over the body’s autonomic processes. The human body performs most of its daily functions on autopilot. Whether it’s regulating internal temperature, setting the steady pace of a heartbeat or rushing lymph and blood to a limb when it’s injured, the body, like a computer, uses preset responses for most external stimuli. Hof’s training aims to create a wedge between the body’s internal programming and external pressures in order to force the body to cede control to the conscious mind. He is a hacker, tweaking the body’s programming to expand its capabilities.
At 60 seconds, with empty lungs, my diaphragm begins to quiver and I have to rock back and forth to keep from gasping. Even so, my mind is strangely calm. My eyes are closed, and I see swirling red shapes behind my lids. Hof explains that the light is a window into my pituitary gland.
Hof promises he can teach people to hold their breath for five minutes and stay warm without clothes in freezing snow. With a few days of training I should be able to consciously control my immune system to ramp up against sicknesses or, if necessary, suppress it against autoimmune malfunctions such as arthritis and lupus. It’s a tall order, to be sure. The world is full of would-be gurus proffering miracle cures, and Hof’s promises sound superhuman.
The undertaking resonates with a male clientele willing to wage war on their bodies and pay $2,000 for the privilege of a weeklong program. Across the room Hans Spaan’s hands are shaking. Diagnosed with Parkinson’s 10 years ago, he had to quit his job as an IT executive, but he claims Hof’s method has enabled him to cut the amount of drugs his doctors insist he needs. Next to him, Andrew Lescelius, a Nebraskan whose asthma can be crippling, hasn’t used his inhaler for a week.
For almost an hour we’ve been cycling between hyperventilating and holding our breath. Every repetition has made it incrementally easier to hold on just a bit longer. Hof tells us the quick breathing adds oxygen to our blood supply so that, at least until we use it up, we don’t have to rely on the air in our lungs to survive. The autonomic urge to gasp for air is based on the mind’s ordinary programming: No air in the lungs means it’s time to breathe. My nervous system hasn’t yet realized there’s still air in my blood.
Ninety-two seconds and my vision starts to cloud over. The room has taken on a red sheen I don’t remember being there before. I may be seeing lights. I let go and allow air to rush in. It’s far from a record, but after only an hour of trying, it’s my longest attempt. I smile with a small sense of accomplishment.
Hof then commands us to undergo another breathing cycle, but this time, instead of holding my breath, he instructs me to do as many push-ups as I can. Raised on a diet of cheese curds and little exercise, I’m out of shape. At home I can manage an embarrassingly feeble 20 before collapsing. Now, with no air in my lungs, I push myself off the floor with almost no effort. They roll out one after another, and before I know it I’ve done 40
I decide I’m going to have to reevaluate everything I’ve ever thought about gurus. Hof is a difficult figure to dissect. On one level he speaks in a familiar creole of New Age mumbo jumbo. There’s a spiel about universal compassion and connection to divine energies. Then, of course, there are the results. His relatively simple exercises make undeniable changes in my body seemingly overnight. Following his prescriptions for a week, I hack my body to perform physical feats of endurance I didn’t think possible and earn confidence I didn’t know I had. As a bonus, I lose seven pounds of fat—which come out in oily clumps during my morning eliminations.
Our goal by the end of the week: to complete an arduous eight-hour climb up a powder-covered mountain, wearing nothing but shorts. It will be my own personal Everest, though in this case the mountain is called Sneˇzˇka. But even with these first routines in the safety of a training room, I’m not sure I’m up for it.
I am at the mercy of Hof, who wears a pointy green hat that makes him look like a life-size garden gnome. A bushy beard frames his piercing blue eyes and ruddy nose, and his body bristles with tightly corded muscles. A six-inch surgical scar across his stomach marks a time he took his training too far and ended up in the hospital. Hof is a savant and a madman. He’s a prophet and a foil. And as is occasionally the case with people who try to cultivate superpowers, Hof’s abilities have come at a heavy price.
Born in the Dutch city of Sittard in 1959, on the eve of Europe’s hippie revolution, Hof spent his early years in the middle of a working-class family of nine children. While the rest of the Hof family learned Catholic liturgy, Wim became fascinated with Eastern teachings, memorizing parts of Patanjali’s Yoga Sutras and scouring the Bhagavad Gita and Zen Buddhism for wisdom. He was keen on exploring the connections between the body and the mind, but none of what he read was quite what he was looking for.
Then, in the winter of 1979, when he was 20 years old, he was walking alone on a frosty morning in Amsterdam’s picturesque Beatrixpark when he noticed a thin skin of ice on one of the canals. He wondered what it would feel like if he jumped in. With juvenile impulsiveness he has never quite shed, he took off his clothes and plunged in naked. The shock was immediate, he says, but “the feeling wasn’t of cold; it was something like tremendous good. I was in the water only a minute, but time just slowed down. It felt like ages.” A wash of endorphins cruised through his system, and the high lasted through the afternoon. He went on to repeat the exercise every day since. “The cold is my teacher,” he says.
The breathing technique emerged naturally. He started by mimicking the rapid breaths people take instinctively when they plunge into icy water, which he says are similar to the breaths a woman takes during childbirth. In both cases the body switches to an instinctual program. When Hof dunked under the ice, he went from rapid breathing to holding his breath. That’s when he began to feel changes in his body.
The way Hof explains it, humans must have evolved with an innate ability to resist the elements. Our remote ancestors traversed icy mountains and parched deserts long before they invented the most basic footwear or animal-skin coats. While technology has made us more comfortable, the underlying biology is still there, and the key to unlocking our lost potential lies in re-creating the sorts of harsh experiences our ancestors would have faced.
Hof trained on his own in obscurity for 15 years, rarely talking about his growing abilities. His first student was his son Enahm. When Enahm was still an infant, Hof took him down to the canals and dunked him in the water like Achilles. While it’s anyone’s guess what nearby pedestrians might have thought of this sight, most of his close friends shrugged off his morning routines as just another eccentricity in an already eccentric city.
Hof did odd jobs, including working as a mail carrier, and took gigs as a canyoneering instructor in Spain during the summers. Money was always a problem, and his wife—a beautiful Basque woman named Olaya—began to show signs of a serious mental disorder. She was depressed. She heard voices. In July 1995 she jumped off the eighth floor of her parents’ apartment building in Pamplona on the first day of the Running of the Bulls.
Sitting at a handmade wooden table in what serves as lunchroom and breakfast nook in his Polish headquarters, Hof recounts Olaya’s death as tears roll freely down his cheeks. “Why would God take my wife from me?” he asks. Confronted with loss and a broken heart, he put all his faith into the one thing that set him apart from everyone else: his ability to control his body. Olaya had never shown interest in Hof’s methods, but he felt he could have done more to help her. “The inclination I have to train people now is because of my wife’s death,” says Hof. “I can bring people back to tranquility. Schizophrenia and multiple-personality disorder draw away people’s energy. My method can give them back control.” It was his call to action. But he still needed a way to announce himself to the world.
His opportunity came a few years later. As winter settled on Amsterdam, a local newspaper ran a series of articles about odd things people did in the snow. Hof called the editor and explained that for the past couple of decades he’d been skinny-dipping in icy water. The paper sent a reporter, and Hof jumped into a nearby lake he frequented. The next week a television crew showed up.
In one famous segment, Hof cut holes in the ice and jumped in while a Dutch news crew filmed. He was drying himself off when, a few meters away, a man stepped on a thin patch and fell through. Hof charged out onto the lake, jumped in a second time and dragged the man to safety. The news crew caught the exchange, and soon Hof wasn’t just a local oddity, he was a local hero. Someone dubbed him the Iceman, and the name stuck.
After that act of heroism, Hof became a household name across the Netherlands. A Dutch television program hosted by the eminent newscaster Willibrord Frequin asked Hof to perform on camera. The gimmick was to have Hof establish a Guinness world record. They planned for him to swim 50 meters beneath arctic ice without breathing. It would be sensationalist fun, but the program would air throughout Scandinavia and give Hof a shot at doing stunts for other channels around the world.
A few weeks later Hof stood on the surface of a frozen lake near the small village of Pello, Finland, a handful of miles from the arctic circle, wearing only a bathing suit. Although the temperature would drop to minus 12 degrees Fahrenheit, his skin glistened with sweat. Below him a diamond-shape hole shot down a meter through the ice. There were two other holes 25 and 50 meters from the first. A camera crew watched as Hof descended and dipped his toe in the periwinkle waters.
On the first day of shooting he was supposed to swim only to the first hole so the crew could get the right shots and feel comfortable with the safety setup. But Hof had other plans. He wanted to surprise and impress the crew by clearing the whole distance in one go. He had done his calculations in advance. One stroke took him one meter, so he would need to do 50 to reach his destination. Taking a giant gulp of air into his lungs, Hof disappeared and began his sprint.
He later recalled that he opened his eyes midway between the first and second hole and could make out a beam of sunlight slicing through the water. But at stroke 29, with the safety of the first hole and rescue team behind him, something went wrong. He hadn’t anticipated what the cold water would do to his eyes. His corneas began to freeze over, and crystallization blurred his vision. Five strokes later he was blind, with only his stroke count to direct him to oxygen. Soon he was off course. At 50 strokes he grabbed around in vain for the rim of the second hole. He turned around thinking maybe he had passed it. He wanted to gasp for air but knew the results would be fatal. At 65 strokes his hope was beginning to fade. Seventy strokes in, just as he began to lose consciousness, he felt a hand wrap around his ankle. A safety diver dragged him to the surface. He knew he had almost died and that his hubris had led him there. Despite that close call, the next day he would set a world record, with the cameras rolling.
The show went on to be a hit and secured him a series of similar on-air stunts for international channels from Discovery to National Geographic. But success came at a price. Although he was capable of incredible feats, Hof’s desire to impress and please the people around him would time and again lead him into near-fatal situations. Should he die, the world might never understand how he had achieved his dramatic results. Hof needed a better plan.
