Wim Hof on the three pillars of his method — and why a daily cold shower may be the most accessible protocol for rewiring stress, mood, and cardiovascular health.
The Moment Cold Water Changed Everything
Before he found the cold, he searched everywhere else. He moved through esoteric disciplines and religious traditions, languages and philosophies — the full breadth of systems human culture has built to explain existence, illuminate the self, and locate the source of what makes us feel most alive. Each offered something; none offered everything. What he sought was not knowledge about depth but direct contact with it — felt, immediate, undeniable in the body. He was still a young man when he understood that the books had taken him as far as they could.
He stepped into freezing water and found what he had been seeking. No words arrived with it — only a quality of connection, immediate and total, to the living reality of his own physiology. The cold did not explain anything; it revealed everything. In the shock of that first immersion, something opened: an awareness of the body's depth, its intelligence, its capacity to respond and adapt far beyond what any tradition had told him to expect. That encounter changed the entire direction of his inquiry.
there were no words but I felt this is it
That was forty-six years ago, and he has not missed a single day since. Through winters in the Netherlands, through expeditions to the North Pole and climbs of Everest in shorts, through ultra-marathons run across desert terrain without drinking — the practice held through all of it. He is sixty-two now. What began as a young man's private search for contact with his own physiology has become a method practiced by people across the world. The ritual has not changed; the understanding of what it does has grown precise.
The method rests on three pillars: specific breathing techniques, gradual cold exposure, and mindset. These are not independent disciplines producing separate outcomes; they form a coherent system in which each element deepens the others. Breathing techniques prepare the body first — quieting ordinary stress, shifting the autonomic nervous system toward calm readiness and clarity, building the physiological foundation that cold will then test. Cold creates the acute demand the body must answer, expanding its capacity for stress and recovery with each session. Mindset determines whether the challenge of cold becomes a source of growing resilience or a wall that limits what the body can learn.
The science has confirmed what the practice discovered. In a landmark controlled study, participants trained in the method were injected with a live bacterial endotoxin — a challenge that produces a reliable immune response in any untrained person. Trained practitioners demonstrated voluntary control over their immune reaction, suppressing it to a degree previously considered outside the reach of conscious influence. That finding — the voluntary regulation of the immune system through breath work and cold — reshaped how researchers understand the boundary between what the body does automatically and what the trained mind can direct.
What makes that finding significant is not its extremity but its implication for ordinary life. If the immune system is genuinely responsive to deliberate practice, the body's self-regulatory capacity is deeper than medicine has long assumed — and more available than most people realize. The method does not require extraordinary conditions to reach that depth; it requires consistency, deliberate breath, and a willingness to step into the cold each morning. The daily practice — cold water, without exception — is how science becomes something you live.
Our next guest is a Dutch extreme athlete known for his ability to withstand freezing temperatures. He's also dedicated his life to helping others reach their full potential. From the Netherlands please welcome Wim Hof. [APPLAUSE] Hi, Wim. Hi, Ellen. Thank you for having me in your show. I am-- You're incredible. You are incredible. I have been looking forward to meeting you for a long, long time. I talk about all the time. Justin Bieber was on the show. We were talking about how incredible you are. Explain how you've discovered this cold therapy and explain it to people who don't know what you do. I'm a person like anybody else yet I wanted to know the depths of myself. So I plunged into esoteric disciplines, into religions, traditions, languages, all kinds of things but nothing could really satisfy me up till the point
that I met this freezing cold water. I went in and I felt like there were no words but I felt this is it. This made me connect so deeply with my physiology, with the depth that we're seeking for which is not in the books but it is inside yourself and the cold knows how to unlock that. So that made me go, like 46 years ago into the cold water. And I never skipped one day of not going into icy water in winter time since then. I'm 62 now. It's amazing. So most people go into-- what's the temperature of that water for instance? That is like, is it 31 degrees Fahrenheit, is like freezing. Yes, freezing.
It is sometimes colder than-- when it's frozen over is when I go in. I make a hole and I'm in the water. And I do my deep experienced breathing techniques staying in the water, it's like deep meditation. It's incredible. You look at that-- we're looking at the video right now, most people would go into hypothermia, not everyone. And you teach these breathing techniques to get ready. But you say there are three pillars to your method and explain what those are. That is specific breathing techniques and then we have gradual cold exposure and we have mindset. And because I went through science it showed to be capable, for example, to defy a bacteria injected. That means a deeper physiology and physiological control over the immune system is there and it
is so simple and accessible and anybody can do it. Yes, And we'll get to the cold shower because I think that's how most people can start, but explain how this affects your nervous system. Yes, by going in a acute, deep, stressful exercise you activate the adrenal axis to spike. And that resets the body to its natural depth by which the physiology suddenly awakens into depth and gets in the control of our will. And that's amazing. Yeah, I'm looking at that thinking I can't do that. I don't think I could sit on that ice. And I mean I'd like to because I want to meet you someday and I do want to try it. But this is something that everyone can practice. Some people should not do it, is that right? Like I mean-- Of course. Yes.
So of course, people with a poor condition or conditions of say chronic diseases and so on we have developed by protocols a method-- we have developed a method that is accessible for anybody even with conditions. And if we go and look at what I've been doing, I have been a researcher of this all. I went to the North Pole, I went up Mount Everest all in my short, into the desert, running without drinking a marathons, and going under the ice and losing my weight. I was the searcher now I found that a cold shower a day keeps the doctor away. As simple as it is that my message to the world is to bring something very accessible and powerful to the human understanding. And it is all scientifically endorsed.
So it is not difficult it is, a matter of doing. Yeah. So if you take for instance-- this is fascinating when I read-- if you take a cold shower it raises your dopamine level 250%. Absolutely. In for example, a depression there is a lack of noradrenaline and dopamine. And going in to a cold shower raises the level of noradrenalin with 530%, dopamine with 250%. It's a natural pill that has no side effects. I think a lot of people here are going to start taking cold showers. I mean I enjoy a hot shower. Does that do anything for you Wim or no? Do you ever take a hot shower? I love hot showers. OK, I do-- I love it-- I do, too but-- yeah, go ahead. Oh, sorry.
Yes, the cold this therapeutical. And once you get used to the cold showers it becomes really addictive. It's a power boost to the body. Afterwards did your veins are so exercised that the blood flow is much better by which you get a lot more energy. And the heart rate is going down because of the millions of little muscles in the vascular system are all optimized and they help the heart, the blood flow go through the system. So the heart rate goes down. People who do regular cold or showers, cold showers the heart rate goes down with 20 to 30 beats a minute 24 hours a day. Wow. That means no stress, high levels of energy. Well, first of all look at you, you're 62 years old as you said. And what time is it where you are right now?
It is half past 12. So in the morning it's yeah, half past 12. OK. And then what time will you wake up in the morning to get in the freezing cold water? It's around between 6 and 7. Well, we all want to be like you Wim, you're amazing. You've created an app where people can learn about your method and take online classes. So if you want to watch more of my interview with Wim you can log on to my website because we had to go a little long because I'm fascinated by him. You can download the Wim Hof method mobile app, it's on iOS and Google Play. And you should learn more about this guy because he is fascinating and can make us all feel better. Wim, thank you so much. Thank you, Ellen. Thank you very much for your great work. Thank you. Thank you, Wim. All right, we'll be right back.

What Cold Does to Your Brain
Step into cold water and the body responds immediately. The adrenal axis spikes — a sharp, acute stress signal that demands the body's full attention, activating systems that ordinary daily life rarely engages at full capacity. Heart rate rises, breathing sharpens, circulation intensifies. Then the reset arrives: the body returns to its natural baseline, but more awake than before — more ordered, more fully present, as if the cold has cleared away the ambient noise of an ordinary morning and left only what is essential.
Not everyone can approach cold exposure the same way, and the method accounts for this. For people managing chronic conditions or poor baseline fitness, carefully designed protocols make the practice accessible without requiring extreme immersion. The cold is introduced gradually — beginning with brief cold showers, extending duration as the body adapts, always working within what the nervous system can receive and process. The goal is not to overcome the body but to work with it, building resilience through deliberate, incremental demands rather than through a single overwhelming challenge.
The neurochemical effects of a cold shower are well-documented and significant. A single session raises norepinephrine by 530% and dopamine by 250% — two of the brain's primary regulators of mood, focus, and energy. Norepinephrine governs alertness and the capacity for sustained attention; dopamine governs motivation, the sense of reward, and the quality of mood across the hours that follow. These are not marginal shifts. They represent a recalibration of the brain's chemical baseline, achieved without pharmaceutical intervention, in the time it takes to shower.
In clinical depression, both dopamine and norepinephrine are typically depleted — their absence shapes the flatness, the withdrawal from engagement, the loss of motivation that the condition produces. The neurochemical signature of a cold shower runs in the opposite direction: toward presence, toward engagement, toward the physiological conditions in which mood can stabilize and focus can return. Cold exposure does not replace clinical care. What it offers is a protocol with measurable neurochemical action — a natural lever on mood and alertness that carries no side effects and requires no prescription.
It's a natural pill that has no side effects
The broader case for cold is built on mechanism, not mythology. The body changes because the stimulus demands a physiological response, and the response — the neurochemical cascade, the autonomic recalibration — produces outcomes you can feel. Focus sharpens in the minutes after cold exposure. Mood lifts and holds across hours that would otherwise carry their ordinary weight. The day ahead looks different than it did sixty seconds before the cold reached you, because the brain operating the day is chemically different from the one that stepped into the shower.
This is what makes the cold shower a genuine protocol and not merely a wellness ritual. A ritual describes a behavior; a protocol describes a mechanism and the outcomes it reliably produces. When dopamine and norepinephrine rise by the percentages the research documents, the brain that emerges from the shower is measurably different from the one that entered. Clarity, motivation, and mood are not feelings that arrived by chance; they are the predictable outputs of a physiological process that cold exposure reliably initiates. That distinction — between ritual and protocol — is the foundation of the method.
A Daily Practice, A Transformed Body
Every cold shower is a vascular workout. The body contains millions of small muscles embedded in the walls of blood vessels — muscles that ordinary daily life rarely engages with deliberate intensity. Cold water reaches the skin and they contract: circulation tightens, the heart pumps against greater resistance, and blood moves through the body with a force and efficiency that a warm, sedentary morning cannot produce. By the time the shower ends, the vascular system has been exercised in a way that few other morning practices can replicate. The blood flow that follows is not imagined; it is earned.
Over time, those vascular muscles adapt. They become more responsive, more efficient, better able to support the heart's work through ordinary daily demands. The cardiovascular system optimizes at rest as well as under load, and the result shows in one clear measurement: resting heart rate. Regular practitioners of cold exposure see theirs drop by twenty to thirty beats per minute — a change sustained around the clock, not just during or after the shower. That is not a marginal improvement; it is a fundamental shift in how the cardiovascular system operates under ordinary conditions.
A lower resting heart rate carries consequences that extend beyond cardiovascular health. A heart operating with greater ease at rest means the body is not quietly spending its energy on the ambient effort of maintaining baseline function. That reserve translates into the quality of the day: steadier energy, less fatigue, a physiological calm that does not compete with focus or deplete attention. Once you practice cold exposure regularly, you discover a kind of quiet equilibrium — a reduction in the low-level stress that most people have come to accept as ordinary. It is ordinary only because they have not yet compared it to its absence.
Once the body adapts to cold, the practice changes character. What first felt like an acute challenge — something to be endured, managed, survived — begins to feel like a return. The body recognizes the cold; it anticipates what follows. The vascular activation, the neurochemical release, the sharpened clarity that arrives within minutes — the body learns to expect these, and the expectation itself becomes a form of motivation. Cold becomes self-sustaining in the most precise sense: the practice builds the capacity it requires, and that growing capacity makes the practice easier to return to.
The entry point for all of this is a shower. No specialized equipment, no extreme conditions, no preparation beyond the decision to turn the dial from warm to cold and hold that position. The cold shower is not a lesser version of the method; it is the method's most honest and accessible expression — available every morning, scalable as the body builds its capacity, executable by almost anyone ready to begin. From there, duration can extend, temperature can drop, breath work can deepen. But the shower is where it starts, and for many, it is where the practice lives permanently — and that is entirely sufficient.
a cold shower a day keeps the doctor away
A cold shower a day is a plainly achievable protocol with compounding returns. The cardiovascular adaptation builds across weeks of consistent practice; the neurochemical benefit — the clarity, the focus, the mood that cold delivers — arrives within minutes of the first session. What the practice requires is not extraordinary pain tolerance or a frozen lake. It requires a consistent act, performed with deliberate attention, repeated until you learn to welcome what you once resisted. That shift — from resistance to recognition, from endurance to anticipation — is adaptation in its purest form, and it is available to anyone willing to begin.
