HACKING THE REMOTE CONTROL OF YOUR NERVOUS SYSTEM
Kasper van der Meulen
Kasper van der Meulen is an author and lifestyle adventurer. He went from being overweight, burnt out and unhappy, to developing superhuman focus, fitness and personal freedom. He put himself through numerous experiments and challenges. He optimized his lifestyle, conquered the cold, ran ultramarathons on his bare feet, tested countless diets, read a ton of scientific literature and explored as many esoteric practices he could find. With over ten thousand hours of experience in teaching science, self-mastery and innovation, he decided to demystify and methodize these principles in a fun and bitesized manner. As a final test of his focus, he wrote his book within 30 days, so that he would have to practice everything he preaches.
His book “MindLift - Mental Fitness for the Modern Mind” became an Amazon best seller. Kasper now travels the world on a mission to teach others to be the healthiest, happiest and strongest version of themselves through transformative experiences and down-to-earth scientific understanding. He is the teacher-teacher of the Wim Hof Academy, he runs experiential retreats in extreme nature and he trains elite performers and professional athletes. All while keeping a playful and creative approach to self-optimisation.

The ability to focus will be the superpower of the twenty-first century.
Summary
- Simple activities like movement, doodling, and drinking water instantly optimize focus because physical engagement activates the thinking brain more effectively than static learning. - The nervous system alternates between fight-or-flight and rest-and-digest states, but modern triggers often keep the body trapped in chronic stress, disrupting natural recovery. - Biohacking involves increasing awareness of the subconscious "black box" to create space between a stimulus and a response, allowing for intentional control over physical reactions. - Physical posture directly influences hormonal levels; holding a "power pose" for just two minutes can significantly reduce stress hormones like cortisol while boosting testosterone. - Breathing serves as a manual remote control for the nervous system, with techniques like box breathing providing an immediate way to shift the body from stress to a state of calm.

Hacking The Remote Control Of Your Nervous System
At Biohacker Summit 2017 Helsinki, Kasper Van Der Meulen Argued That Focus Was Not A Talent But A Trainable Physiological Skill
The room in Helsinki did not begin with a flourish. It began with noise.
At Biohacker Summit 2017 Helsinki, on Friday 13 October 2017, Kasper van der Meulen stepped on stage and did something quietly radical for a gathering devoted to optimisation. Before offering a theory, before presenting a hack, before naming the nervous system as the central battlefield of modern life, he asked the audience to stop. Put everything down. Close their eyes. Breathe through the nose. Notice what remained inside them after the previous talks, the ambient sound, the low-grade cognitive static.
It was a small intervention, almost modest. But it contained the thesis of his presentation, "Hacking The Remote Control Of Your Nervous System: Strategies For Focus & State Management". In a century intoxicated by speed, van der Meulen suggested that the first frontier was not productivity software, wearable data or stimulant culture. It was awareness. It was the ability to detect, with honesty and precision, what state the body was already in.
“Between stimulus and response, there is a space,” he said. “In that space lies our choice, and in that choice lies our freedom. That is where we begin.”
A Modern Mind Trapped In An Ancient Body
Van der Meulen, an author, teacher and lifestyle adventurer, spoke with the authority of someone who had rebuilt himself in public. His biography was woven into the talk not as self-mythology but as evidence. He described a life that had lurched through distraction, addiction, panic and physical decline before becoming a long experiment in self-mastery. Once overweight, burned out and unhappy, he had gone on to test diets, breathing methods, cold exposure, meditation, ultrarunning and behavioural change with near-clinical intensity. His bestselling book, *MindLift - Mental Fitness For The Modern Mind*, was itself written in 30 days as a final ordeal in focus.
Yet his central point was strikingly unsensational. Human beings, he argued, were failing in modern environments not because they were weak, but because they were mismatched.
The body, after all, had not evolved for push notifications, ambient urban stress, open-plan offices and the endless low hum of digital alarm. It had evolved for the cave and the hunt. For danger that was immediate, physical and finite. The sympathetic nervous system, often reduced to the shorthand of fight or flight, was brilliant at preparing a human to face a predator, search for food or defend territory. The parasympathetic state, rest and digest, was meant to restore, repair, reproduce and metabolise.
The trouble was not that these systems existed. The trouble was that modern life had become expertly engineered to keep one of them switched on.
The Body Keeps The Score Before The Mind Can Explain It
Van der Meulen returned repeatedly to one insight: physiology often moved before conscious thought had caught up. He recalled a moment from his teens, when he attempted to walk back to school after a troubled spell away. As he headed toward the gate, his heart pounded, his breath shortened, his palms sweated. He turned back toward the house and the symptoms eased. He walked toward school again and the panic returned.
Nothing in the external world had changed. The threat was internal, then embodied.
That memory became a pivot. It taught him, he said, that a tiny shift in mental focus could provoke an immediate shift in the body. A thought could become pulse, breath, adrenaline, panic. The nervous system was not some abstract concept in a textbook. It was a live switchboard, constantly translating perception into chemistry.
“Your body and your brain are built to survive first and then to thrive,” he told the audience.
The line landed because it named a harsh truth about contemporary life. Survival mechanisms are sticky. They escalate quickly and settle slowly. A person can be safe in reality and still physiologically preparing for disaster.
Why Focus Begins With Movement, Not Stillness
One of the more refreshing elements of the talk was van der Meulen’s impatience with the way schools and workplaces often demand concentration while sabotaging the conditions that make it possible.
He offered a list of deceptively simple tools to improve focus immediately: movement, doodling, chewing gum, drinking water, standing up. It sounded almost unserious until he explained the mechanism. The brain, he said, was a single-track device. Multitasking was more myth than skill. But light motor engagement could support cognition because movement activated neural systems that aided thinking.
“Your motor cortex, your moving brain, actually activates your neocortex, your thinking brain,” he said.
In one stroke, he challenged the old image of the ideal learner as still, silent and motionless. The fidgeting student, the doodler, the person who needed to move, might not be disengaged at all. They might be trying, instinctively, to wake up the machinery required to think.
Stress Was Not The Enemy. Being Stuck Was.
The most useful distinction in the presentation was not between calm and stress, but between flexibility and entrapment.
Stress itself, van der Meulen argued, was not inherently pathological. The lion chasing the gazelle and the gazelle fleeing the lion shared much of the same physiology: elevated heart rate, rapid breath, mobilised sugar, sharpened senses. The biological pattern was similar. The subjective experience was not. One pursued. One escaped. One had positive stress. The other endured terror.
The deeper problem in modernity was chronic activation without resolution. Humans did not just enter fight or flight. They lingered there. They carried it into meals, meetings, commutes, inboxes and bedrooms. They ate in a rush, scrolled through outrage before sleep, checked news feeds like prehistoric sentries scanning for predators. The threat never fully materialised, but the body kept preparing anyway.
What should have been a temporary spike became a baseline.
This, in van der Meulen’s telling, was how burnout crept in: not always as collapse after a dramatic peak, but as the gradual loss of the body’s ability to switch states cleanly. At first, people knew only stress and sleep. Eventually, they knew only exhaustion.
“Health is a skill of balance and resilience, the ability to switch your nervous system between different states,” he said.
The Black Box Between Trigger And Reaction
If the nervous system was a remote control, the first button was awareness.
Van der Meulen described daily life as unfolding through what he called a black box: the largely subconscious space between what happened to us and how we responded. Most people, he suggested, lived at the mercy of this space because they rarely examined it. An email arrived and irritation flared. A social slight appeared and the body tightened. Sugar, anger, anxiety, procrastination, compulsive scrolling: all could emerge before a person had consciously understood the sequence.
The numbers he cited were stark. Most processing, he said, happened below conscious awareness. Only a tiny fraction was available to deliberate thought. That made self-observation not a luxury but a practical necessity.
His advice was simple enough to sound almost old-fashioned. Keep a nervous system diary for 30 days. Track the moments of greatest activation and greatest calm. Identify the triggers. Notice whether the body truly settled or merely called a lesser state of stress relaxation. Observe meals, social media, work intensity, evening habits, sleep.
To biohack, in his formulation, was not merely to add gadgets or supplements. It was to study one’s own state with enough honesty to intervene before the dominoes fell.
Power, Posture And The Politics Of Physiology
There was also a democratising streak to van der Meulen’s method. He was interested in techniques that did not require expensive technology and that acted directly on the body’s circuitry.
Posture was one example. He argued that the way a person held themselves could alter hormonal and emotional patterns, making the body either a collaborator in stress or a route out of it. A so-called power pose, held briefly, could shift the organism away from collapse and toward confidence. Whether one treated that claim as settled science or pragmatic cueing, the broader point was difficult to dismiss: the body was not just expressing state, it was helping generate it.
This was the recurring elegance of the talk. So much of what people experienced as mood, focus or willpower was, he insisted, deeply entangled with breath, muscle tone, digestion, sensory load and physical orientation.
Breath As The Ultimate Remote Control
Then came the clearest claim of the session, delivered with the conviction of a man who had spent years in extreme cold and deliberate discomfort testing it.
“Your breath is the ultimate remote control of your brain.”
The audience would get a full workshop on breathing the next morning, he promised, but even in this theory-heavy talk the argument was compelling. Breath reflected mental state, yes, but it also shaped it. Panic sped the breath, but a sped breath could also induce panic. Relief produced a sigh, but a deliberate sigh could create relief. Yawning signalled tiredness, but it could also deepen it.
This two-way traffic mattered because it meant that people were not wholly trapped inside unconscious responses. Through practices such as box breathing, they could manually signal safety to the body, lower physiological arousal and reclaim a measure of choice. In a culture that often framed focus as a matter of discipline alone, van der Meulen reframed it as state management.
The implication was both urgent and humane. Before asking more of the mind, one might need to reassure the body.
A Case For Resilience In The Age Of Overload
What made the presentation resonate was its refusal to separate performance from humanity. Van der Meulen spoke the language of biohacking, certainly. He referenced intermittent fasting, cold exposure, movement protocols and behavioural experiments. But beneath the optimisation lay something gentler and more serious: the belief that many people were not failing because they lacked ambition, but because their systems had been pushed too far from the rhythms they were built to sustain.
He was not offering escape from stress, which would be impossible, nor a fantasy of permanent calm, which would be useless. He was offering fluency. The capacity to move between activation and recovery without becoming trapped in either.
In the end, the argument he made at Biohacker Summit 2017 Helsinki was not really about hacking at all, at least not in the gaudy sense the word sometimes implies. It was about learning the body’s language well enough to stop living at the mercy of every alarm it sounded.
Focus, he suggested, might indeed be the superpower of the twenty-first century. But it would not be won through force. It would be built through balance, awareness and the steady reclaiming of that small space between what hits us and what we become.
