The Wim Hof Method (WHM) has gained global attention as a unique practice combining breathing exercises, cold exposure, and meditation. Named after its creator, Wim Hof (nicknamed “The Iceman” for his astounding feats in extreme cold), this method promises improved physical and mental well-being.
Practitioners of the Wim Hof Method claim it can boost energy, improve immunity, reduce stress, and even alleviate symptoms of some illnesses. Such claims naturally invite both enthusiasm and skepticism.
In this article, we’ll break down what the Wim Hof Method involves, explore its potential benefits and the science behind them, and discuss tips for safely trying the method.
Who is Wim Hof?
Wim Hof, also known as the Iceman, is a Dutch extreme athlete known for his rambling thoughts that seem to come together to form a deep, scientifically relevant message that describes the innate ability of humans to have control over their physical, mental and emotional health by using the three pillars of the Wim Hof Method – breath, movement and cold exposure.
Wim Hof began with his own practice and through developing his own unique version of an ancient yogic breathing practice, which is scientifically described as controlled hyperventilation breathing, and the iconic cold water therapy he has managed to break numerous world records, create new scientific and ground breaking research on the human body and capture thousands of people around the world in somewhat of a cult following.
The question of “Is Wim Hof legit?”, is best explained by his crazy feats of physical display and mental resilience as well as the numerous science experiments supporting his claims. Over the years the Wim Hof Method has taken people from all over the world including Australia, USA, UK, NZ, Europe and Asia through the fundamentals of the breathing technique, movement and cold exposure protocols that are unique to the method, and has helped improve millions of lives!
Wim Hof is a truly remarkable person who has climbed Mount Kilimanjaro in shorts, run a half marathon above the Arctic Circle barefoot, and placed himself in an ice cube covered container for more than 112 minutes. He has rewritten some of the previously understood science of having limited control of our autonomic nervous system, and shown that we can in fact influence our nervous system and immune response through breath, cold and movement.
What Is the Wim Hof Method?
The Wim Hof Method consists of three pillars as described by Wim Hof himself:
Breathing Technique: Often called Wim Hof Breathing, it involves cycles of deep, rhythmic hyperventilation followed by breath retention. A standard practice is to take ~30 quick deep breaths (fully inhaling and then letting go, not forcefully exhaling) and after the last inhale, exhale and hold your breath with empty lungs for as long as is comfortable, then take a deep inhale to recover. This cycle is typically repeated for several rounds. The breathing is done in a safe environment (seated or lying down, never while driving or in water) because the hyperventilation can cause lightheadedness or tingling sensations. People often describe feeling a rush or high afterwards due to changes in blood gases and adrenaline.
Cold Exposure: The method encourages gradual exposure to cold. This can start with practices like ending your shower with 15-30 seconds of cold water and can build up to taking ice baths or cold plunges for a few minutes. Wim Hof famously has submerged himself in ice and swum under polar ice – though you certainly don’t have to go to those extremes! Regular cold showers or occasional ice baths are the usual practice. Cold exposure is believed to help train your circulatory system, reduce inflammation, and build mental resilience.
Commitment (Mindset): The third pillar is developing the right mindset, focus, and dedication. Mastering the controlled breathing and withstanding cold requires mental fortitude. Practitioners often incorporate meditation or visualization to maintain calm during the breathing and cold exposure. This pillar is about consistency and mental strength – committing to the practice and pushing through discomfort safely.
According to Wim Hof, the combination of these three pillars “strengthens the connection between body and mind.” He claims it gives you influence over your autonomic nervous system and immune response, abilities traditionally thought to be beyond conscious control.
Wim Hof himself is known for 26 Guinness World Records, including climbing part of Mount Everest in just shorts, running a half marathon above the Arctic Circle barefoot, and sitting in an ice bath for nearly two hours. He attributes these superhuman feats to his method.
The Science Behind Wim Hof Method
Breathing Effects
The breathing exercises in WHM involve hyperventilation followed by breath holding. This has distinct physiological effects. Hyperventilating (rapid deep breathing) blows off a lot of carbon dioxide from your blood, which can raise your blood pH (making it more alkaline) and reduce the urge to breathe. This is why you can hold your breath longer after hyperventilating – there’s less CO₂ to trigger the breathing reflex. During the breath hold, oxygen levels drop somewhat and CO₂ gradually rises again. This cycle can stimulate a mild stress response in the body.
Research shows that WHM breathing activates the sympathetic nervous system – the “fight or flight” branch of our nervous system – in a controlled way. One landmark study found that people trained in the Wim Hof Method were able to voluntarily spike their adrenaline levels through the breathing technique and meditation. This is remarkable because adrenaline is usually released in extreme situations, yet these practitioners produced it on demand while calmly lying in a lab. This adrenaline surge was associated with a tamping down of the immune response.
Immune System Influence
In that same study (Kox et al., 2014), researchers injected participants with a bacterial endotoxin (a component of bacteria that normally triggers a strong immune reaction with fever and inflammation). The individuals who practiced Wim Hof’s breathing and cold training produced more anti-inflammatory chemicals (like interleukin-10) and fewer pro-inflammatory cytokines in response to the toxin. In plain terms, they had a milder flu-like reaction than the control group. They reported feeling less sick, and their bodies showed lower levels of inflammatory proteins like TNF-α, IL-6, and IL-8 compared to those who didn’t do the method. This suggests the Wim Hof Method can voluntarily temper the immune system’s reaction. Wim Hof often cites this study as proof that we can “turn the thermostat down” on inflammation in our bodies through his method.
Later studies and a recent systematic review have supported these findings. A 2024 systematic review of research on WHM concluded that the method may reduce inflammation in both healthy people and those with certain conditions by increasing epinephrine (adrenaline) levels, which in turn boosts anti-inflammatory IL-10 and lowers pro-inflammatory signals. This controlled stress response might explain anecdotes of people with autoimmune diseases or inflammatory issues feeling better when practicing WHM. There was even a small trial where patients with an inflammatory arthritis (axial spondyloarthritis) underwent WHM training; results showed reduced inflammation and disease activity markers compared to controls.
Cold Exposure Benefits
Cold showers and ice baths are known to cause a rush of adrenaline and noradrenaline as well, and they can help reduce muscle inflammation (many athletes use ice baths for recovery). Cold exposure as part of WHM likely works synergistically with the breathing. Physically, regular cold showers may improve cardiovascular circulation (blood vessels constrict in the cold and open back up after, like exercise for your blood vessels). Mentally, exposing yourself to cold builds resilience – it’s uncomfortable at first, but with practice you learn to relax in that discomfort, which can translate to better stress management in other areas of life.
There’s also interest in how cold exposure might activate brown fat (brown adipose tissue) which generates heat and can burn calories, potentially aiding metabolism. Wim Hof’s own ability to maintain his core temperature in extreme cold fascinated scientists; one study found he could influence his autonomic nervous system and keep his skin temperature more stable during cold via his meditation techniques. Not everyone will gain extreme cold tolerance, but even regular folks often report feeling more cold-resistant and getting fewer common illnesses when routinely taking cold showers – possibly due to subtle immune system training or improved circulation.
Mental Effects
The combination of breathing and cold is, in a way, a form of controlled stress that trains you to handle stress better. People often report after doing WHM breathing that they feel a sense of calm euphoria or clarity. This likely comes from the rush of endorphins and adrenaline, followed by a rebound of parasympathetic (relaxation) activity. Many use the breathing as a sort of meditation to improve focus. The discipline of taking a daily cold shower or doing breathing exercises can also build mental fortitude and confidence. It’s a bit like saying: “I did something hard and uncomfortable this morning (sat in cold water, held my breath); now I feel ready to take on other challenges.”
Benefits of the Wim Hof Method
Enthusiasts of WHM report a wide range of benefits, including:
Reduced Stress and Anxiety: The method can induce a calm yet energized state. The deep breathing and cold exposure both trigger a release of endorphins and neurotransmitters that can elevate mood. Many people say that focusing on the breath and then experiencing the cold helps quiet the mind, leaving them less anxious. Over time, regularly practicing WHM might lower baseline levels of stress hormones. In a survey of thousands of practitioners, improved stress management and mood were commonly reported benefits.
Improved Immune Function: As discussed, WHM can increase anti-inflammatory activity in the body. Practitioners often claim they get sick less often (like fewer colds) after adopting the routine of breathing and cold showers. Some small studies and anecdotal cases suggest potential benefits for people with autoimmune conditions, though more research is needed. The method essentially teaches your body to control inflammatory responses better, which could translate to a more robust immune system.
Increased Energy and Alertness: The breathing technique oxygenates your body and, together with cold showers, gives a surge of adrenaline and endorphins. Many people do WHM in the morning in lieu of or alongside their coffee because it makes them feel alert and invigorated. The hyperventilation phase elevates your heart rate and epinephrine, which can feel like a natural energizer. Users often describe a sustained energy throughout the day with regular practice.
Enhanced Focus and Willpower: There’s a mental training aspect to the WHM. Doing those long breath holds and enduring the cold requires concentration and overcoming discomfort. Practicing this daily can strengthen your willpower and focus. It’s like exercise for your brain’s discipline muscle. This can carry over into better focus at work or discipline in other habits. Some also find the breathing gives a meditative, mindfulness benefit, training them to be present and in control of their physiology.
Better Mood (Help with Depression): Anecdotally, some people struggling with depression or mood swings have turned to WHM as a complementary practice. The combination of breathwork and cold exposure can trigger the release of mood-enhancing chemicals (neurotransmitters like norepinephrine, for example, which is linked to arousal and mood). Also, the sense of accomplishment from pushing your boundaries can improve self-esteem. A small pilot study in 2022 on WHM training for people in extreme environments suggested it might help reduce stress responses, and ongoing research is examining its effects on mental health more formally.
Physical Benefits and Recovery: Athletes sometimes use the method for recovery. The breathing can aid in oxygenating the body and possibly removing lactate (though one WHM breathing session did not show improved exercise performance in a small study). The cold exposure definitely helps with post-exercise inflammation and muscle soreness. Some also report improvements in chronic pain or fibromyalgia symptoms, theorizing that the method’s anti-inflammatory effect plays a role. Additionally, by improving circulation, it may support overall cardiovascular health.
It’s important to note that individual experiences vary. Not everyone will feel all these benefits, and some effects can be subjective. Scientific research, while promising in areas like inflammation and stress hormones, is still catching up on other claims. For instance, we have solid evidence for the immune and hormonal responses, but rigorous studies on things like long-term anxiety reduction or athletic performance are still limited or mixed. Early results are “promising” but more research is needed
How to Practice the Wim Hof Method (Safely)
If you’re interested in trying the Wim Hof Method, here are general guidelines:
1. Breathing Exercise
Find a safe, comfortable place to sit or lie down. It’s crucial not to practice the breathing in any situation where losing consciousness would be dangerous (for example, never do WHM breathing while driving, in water (to avoid shallow water blackout), or standing up). Start with the guided method:
Take 30 deep breaths: Inhale through your nose or mouth deeply into your belly and chest, then let the air go (exhale) without forcing it all out. The exhale is relaxed. You will feel like you’re “over-breathing” – that’s the point. You might feel tingling in your hands/feet or light-headed; that’s okay, but if it feels too intense, slow down a bit.
After the 30th exhale, exhale fully and then hold your breath (don’t inhale yet) as long as comfortable. Because of the prior hyperventilation, you might be able to hold for 1 minute or more with little urge. Hold until you just start to feel an intense urge to breathe.
When you need to inhale, take a deep recovery breath in and hold that inhale for about 15 seconds, then release.
That completes one round. Start the next round by again doing the 30 deep breaths and repeat the cycle. Beginners often do 3 rounds; you can build up to 4 or 5 rounds.
After the breathing, you generally feel very relaxed, sometimes a bit euphoric or clear-headed. Many like to sit in that feeling for a minute and enjoy a calm meditative state. Some may do light yoga or push-ups right after the breathing (caution: doing push-ups immediately after the breathing can be interesting because you’re oxygenated; just be careful not to get dizzy).
2. Cold Exposure
If new to cold exposure, start slow. In your next shower, at the end, turn the water to cold for maybe 15 seconds. It will be a shock; focus on calm, slow breathing to control the urge to gasp. Over days and weeks, try to extend that cold finish: 30 seconds, then 1 minute, etc. The goal is to train your mind and body to handle cold. Many WHM practitioners aim for a daily cold shower of 2-5 minutes. You can also practice by taking short cold plunges in a tub or using ice baths if accessible, but again gradually increase your time and intensity.
During cold exposure, it’s normal for your heart rate and breathing to spike initially. The training is in bringing your breathing under control – try to breathe in through the nose and out through the mouth slowly. You might even smile to relax your face (Wim Hof often suggests this). You’ll find that after about 30-60 seconds, the cold becomes more tolerable as your skin numbs a bit and your mind accepts the sensation.

3. Mindset/Commitment
Treat the process as a practice. Consistency is key to getting benefits. It helps to do the breathing exercise daily, maybe each morning. Approaching the method with an open but disciplined mindset will help you push your boundaries safely. Some days will be easier than others – that’s okay. The “commitment” pillar is about showing up and doing it regularly, and using focus (like mindfulness or even upbeat determination) to get through the challenging moments (like the urge to hop out of a cold shower).
Safety Tips
Always listen to your body. Mild light-headedness is common with breathing, but you should always remain in control. If you feel too dizzy, stop the breathing exercise. With cold, never stay in so long that you shiver uncontrollably, or after-drop (continued cooling) becomes an issue.
It’s better to start with short exposure and build up. People with certain health conditions (like serious heart issues, uncontrolled high blood pressure, or a history of cold-related problems) should consult a doctor before doing intense cold exposure. Pregnant women are often advised to avoid extreme breath holds or heavy cold exposure as well.
The Wim Hof Method is generally safe for healthy individuals when done as instructed. The biggest risks come from not following guidelines – for example, if someone foolishly tried the breath holds underwater, they could faint and drown. So stick to the rules Wim and trainers emphasize: no breathing exercises in risky environments, and respect the gradual adaptation to cold.
What Does the Research Say?
As of 2025, the Wim Hof Method has been the subject of several scientific studies, though it’s still relatively new in research terms. We’ve already mentioned the landmark 2014 study in PNAS showing conscious control of the immune response, and the 2024 systematic review in PLOS ONE which found overall that WHM shows promising anti-inflammatory effects. Here’s a quick rundown of notable findings:
Inflammation and Autoimmune Conditions: WHM training was linked to reduced inflammatory markers and increased anti-inflammatory IL-10 in multiple studies. A small trial on people with an inflammatory arthritis (as mentioned) showed improvements. This is encouraging for potential therapeutic use, but larger clinical trials would be needed to establish it as a treatment adjunct.
Stress Hormones: WHM clearly can raise stress hormones like epinephrine sharply during practice, but interestingly, this doesn’t translate to feeling more “stressed” – on the contrary, people feel good after. It’s like a workout for your stress system that might make it more efficient. Some research also measured cortisol (a stress hormone) – one study found WHM practitioners did not have dramatically different cortisol at baseline than others, though cortisol may rise during the breathing temporarily. It’s complex, but essentially WHM may help modulate stress responses rather than chronically elevate or decrease cortisol in one direction.
Metabolic and Other Effects: One pilot study looked at whether WHM breathing before exercise could enhance performance (in sprint cycling) and found no significant improvement in anaerobic performance from a single session. So it might not be an ergogenic aid in that sense, but that was one small study. Another case study showed WHM practices might influence brain and metabolism (like waste clearance in the brain) but that’s highly theoretical at this point.
Mental Health: A randomized controlled trial (ongoing or recently completed, as per search results) is examining WHM vs other breathing in people with high stress. We don’t have published results at the moment of writing, but it underscores that the scientific community is interested in WHM’s impact on anxiety, depression, and well-being. The large survey Hof did with RMIT (over 3,000 respondents) found self-reported improvements in mood, focus, and various health areas, but that’s subjective data. Still, it’s promising and warrants controlled studies.
In summary, research so far supports key claims (inflammation control, autonomic nervous system influence) and finds the method generally safe for healthy people, but more research is needed to fully understand and verify many of the broader health claims
Conclusion: Should You Try the Wim Hof Method?
The Wim Hof Method offers an intriguing blend of ancient practices (breathwork and meditation have been around for ages, similar to Tummo breathing in Tibet) with modern twists and a charismatic figurehead. Many have found it to be a powerful tool for improving their well-being, giving them more energy, resilience, and a sense of control over their body and mind. The scientific evidence, while still emerging, does lend credibility to some of the benefits like reduced inflammation and better stress response.
If you’re a healthy individual, trying out the WHM is relatively simple and free – all you need is guidance (plenty of free videos or the official Wim Hof app) and some willingness to endure cold water! Always prioritize safety: do it in a safe environment, and don’t push beyond your limits, especially with breath holds or ice water.
It’s not a magic bullet or a substitute for medical treatments or a healthy lifestyle, but rather a complementary practice. Think of it as an exercise routine for your autonomic nervous system. Just like going to the gym strengthens your muscles, doing WHM might strengthen your stress tolerance and immune function.
For some people, the intense sensations (tingling, hyperventilation, cold shock) might not be enjoyable – and that’s okay. It’s not for everyone. You can also adapt the practice: maybe you like the breathing but not the cold, or vice versa. Even simply ending showers cold without the breathing, or doing the breathing as a standalone morning ritual, can have partial benefits. Wim Hof’s mantra is “Happy, Strong, Healthy” – the ultimate goal is to help you feel that way.
In conclusion, the Wim Hof Method is a fascinating intersection of self-discipline, physiology, and personal growth. Early science says it’s more than just hype – our bodies do have untapped potential to regulate systems we once thought automatic. If practiced wisely, WHM could be a valuable addition to your wellness toolkit, helping you breathe a little deeper, weather the storms of life (and the cold!) with more confidence, and perhaps unlock a new level of mind-body connection.
As Wim Hof often says, “Breathe mother***!”* – a cheeky reminder to breathe deeply and embrace your inner power.
