Wim Hof Method for Beginners: Breathing, Cold & the Best Tools for Your Practice
The Wim Hof Method is best known for two things: intensive breathing exercises and voluntary cold exposure. On social media, it can sound like a shortcut to more energy, better recovery and a stronger immune system. The reality is more restrained — and interesting precisely for that reason.
The method can be a deliberately structured physical challenge. The breathing temporarily changes carbon dioxide and oxygen levels, while cold water triggers a pronounced stress response. Both can produce intense sensations. However, this is not proof of a health benefit or a reason to turn breath holds or water temperatures into a competition.
You do not need an ice tub or expensive technology to begin safely. A stable lying position, a short guided breathing session and a cautious cold finish to your shower are enough. Measuring devices can add data later, but they replace neither bodily awareness nor medical advice.
Important safety warning: The Wim Hof breathing exercise can cause dizziness and, in rare cases, loss of consciousness. Practise only while sitting or lying in a safe place. Never practise in or near water, in the shower or bath, while swimming or driving, or wherever a brief loss of control could be dangerous. During all cold exposure, breathe normally and do not hold your breath.
What does the Wim Hof Method include?
The method is usually divided into three elements:
- Breathing: Several deliberate deep breaths alternate with a relaxed breath hold after exhaling.
- Cold: The body is gradually introduced to cold water — for beginners, preferably through a brief cold finish to a shower.
- Mindset and concentration: Attention, calmness and regular practice aim to prevent the method from becoming an uncontrolled performance test.
The three elements belong to the overall approach, but do not have to follow one another immediately. Above all: Never use the special breathing technique in water. During a cold shower or a later cold bath, breathe normally and with control.
What happens during the breathing exercise?
Repeated deep breaths temporarily lower carbon dioxide levels in the blood. This shifts pH towards alkalinity and can delay the natural urge to breathe. During the following breath hold, oxygen saturation can fall considerably.
Tingling, warmth, mild light-headedness or altered bodily awareness can occur. These sensations are not a sign of quality. Stronger tingling, longer breath holds or particularly low readings do not automatically mean a better session.
A cautious breathing routine for beginners
The sequence below follows the basic principle of the official Wim Hof breathing exercise, but is deliberately conservative.
1. Get into a safe position
Lie on a mat or bed, or sit securely with back support. Make sure you cannot fall. Allow about 10–15 uninterrupted minutes.
2. Thirty calm, deep breaths
Breathe deeply through your nose or mouth, letting your abdomen rise first and then your chest. Let the air flow out gently without forcing it out.
- A steady rhythm rather than maximum speed
- Keep shoulders and jaw as relaxed as possible
- No forced hyperventilation
- Return to normal breathing immediately if you become noticeably dizzy
3. A relaxed breath hold after exhaling
After the last breath, let the air flow out gently and pause. End the breath hold at the first clear urge to breathe. Do not time yourself if that encourages you to push through. There is no meaningful record you need to achieve.
4. Recovery breath
Breathe in calmly and deeply, hold for approximately 10–15 seconds, then release gently.
5. Two or three rounds
Two rounds are enough to begin with. If you tolerate the exercise well, you can later perform three rounds. Afterwards, remain lying or sitting for about two minutes and stand only when you feel completely steady.
Stop immediately: for chest pain, severe or persistent dizziness, unusual breathlessness, a racing heart, visual disturbance, confusion, painful muscle cramps or a feeling that you may lose consciousness. Fainting is not a normal training achievement; it clearly indicates excessive stress.
Cold exposure for beginners: a shower is enough
An ice bath is not a necessary starting point. Cold water can abruptly change breathing, heart rate and blood pressure. The RNLI considers water below 15°C cold enough to pose a significant cold-shock risk. The following routine therefore starts exclusively in the shower.
Four weeks without performance pressure
| Period | Cold shower finish | Purpose |
|---|---|---|
| Week 1 | 15–30 seconds | Exhale calmly and learn your response |
| Week 2 | 30–45 seconds | Relax your shoulders; do not fight the cold |
| Week 3 | 45–60 seconds | Maintain steady breathing |
| Week 4 | Up to around 60–90 seconds | Progress only if the previous level was well tolerated |
Start with your legs and arms, then move the water over your trunk and back. Your head does not have to go under the cold stream. The temperature should feel clearly cool but manageable. End the session if you gasp frantically, cannot calm your breathing or begin to panic.
Dry yourself afterwards, put on warm clothing and move gently. Uncontrollable shivering, numbness, coordination problems, confusion, chest pain or persistent discomfort are reasons to stop and may require medical help.
What about ice baths or open water?
Neither belongs in a beginner plan. A bath or plunge pool adds risks because the whole body is suddenly exposed and getting out independently may become harder. Open water adds currents, depth, slippery entry points and drowning risk.
When trying a cold bath later:
- Never do it alone.
- Never do it after Wim Hof breathing or while holding your breath.
- Never do it under the influence of alcohol or drugs.
- Enter slowly and with control.
- Initially keep your head and neck above water.
- Prepare a safe exit and warm clothing beforehand.
- Do not experiment with the lowest possible temperature or longest duration.
What does the research actually say?
The best-known study was published in 2014. Twelve trained healthy men and twelve controls received bacterial endotoxin under medical supervision. Through the breathing, cold and meditation techniques they had learned, the trained group could influence adrenaline release and certain inflammatory markers, and reported fewer flu-like symptoms.
This was an interesting proof of concept, not evidence that the method prevents infections, treats autoimmune disease or reliably improves general health.
A 2024 systematic review found nine publications covering eight studies. Results for inflammatory responses were promising, while findings for athletic performance and breathing were mixed. Almost all studies had small groups, predominantly male participants and an elevated risk of bias. The authors therefore emphasised the need for larger, methodologically stronger studies.
Cold water alone is not a simple “inflammation brake” either. A 2025 meta-analysis found an initial rise in certain inflammatory markers immediately after cold-water immersion. Some findings on stress, sleep and quality of life were positive, but the overall number of studies, protocols and populations remained limited.
A fair summary is:
- The method produces measurable short-term physiological responses.
- There are interesting but still limited findings for certain inflammatory markers.
- Reliable benefits for immune defence, disease treatment, sleep, mood or athletic performance are not sufficiently established.
- Personal experiences can be positive, but do not replace controlled long-term studies.
Which tools are actually useful?
None of the devices below is necessary to begin the method. They serve very different purposes and should not be treated as safety guarantees.
| Tool | Potential use | Main limitation |
|---|---|---|
| Water thermometer | Objectively record water temperature | Does not prevent cold shock |
| Pulse oximeter | Observe SpO₂ and pulse at specific moments | Readings may be delayed or inaccurate |
| Polar H10 chest strap | Record heart rate and RR intervals with a compatible app | Not a medical diagnosis or permission to push harder |
| Inspiratory muscle trainer | Train the inhalation muscles separately against resistance | Not part of the Wim Hof Method |
1. Water thermometer: the most practical cold-exposure tool
Anyone later using a bath or suitable cold plunge should not guess the water temperature by feel. A simple thermometer makes sessions comparable and prevents an unnoticed temperature change from becoming an unintended increase in intensity.
The analogue TFA Dostmann bath thermometer 14.3018.02 needs no battery and is sufficient for basic temperature checks. What matters is not the lowest possible number, but a clear, gradual progression.
Who may find it useful? People planning a supervised cold bath after a longer period of adapting through showers, who want to record temperature and duration.
Who does not need it? Beginners who use only a cold shower finish.

2. Beurer PO 30: observe SpO₂, not prove safety
The Beurer PO 30 measures estimated arterial oxygen saturation and pulse at the finger. Its colour display and one-button operation make occasional readings straightforward.
However, interpretation during Wim Hof breathing is difficult. Pulse oximeters respond with a delay, and cold fingers, poor circulation, movement, skin temperature, nail polish and other factors can affect results. The device must therefore not be used to keep extending a breath hold or to pursue a low reading as a training goal.
If you measure, do so lying down with a warm, still hand and without simultaneously pressing the device's controls. Single readings are less informative than a carefully collected trend. Unusual readings or symptoms require medical assessment, regardless of what the display shows.
Who may find it useful? Data-interested adults who also want to use the device appropriately outside the breathing exercise.
Who does not need it? Anyone who simply wants a safe, straightforward introduction to the method.

3. Polar H10: compare heart-rate and HRV trends
The Polar H10 records heart rate and RR intervals through a chest strap and transmits data via Bluetooth or ANT+ to compatible devices and apps. This allows calm measurements before and after a breathing or cold routine to be compared under similar conditions. HRV analysis requires a compatible app or suitable Polar device.
A single HRV value proves neither recovery nor reduced stress. Sleep, time of day, body position, breathing, alcohol, training, infection and measurement duration affect the result. Measurements become useful when repeated at the same time of day under conditions as consistent as possible.
For this purpose, use the chest strap on dry land before or after the session. Water resistance does not make a cold bath safer.
Who may find it useful? People who already follow structured training and record long-term heart-rate or HRV trends.
Who does not need it? Beginners who are not interested in repeatable measurements.

4. POWERbreathe Plus Light: separate inspiratory muscle training
The POWERbreathe Plus Light Resistance creates adjustable resistance during inhalation, training the muscles used to breathe in. This may be useful for endurance or respiratory-muscle training, but it is neither part of nor necessary equipment for the Wim Hof Method.
Use the trainer in a separate session according to its instructions. Do not combine its resistance with the rapid breaths or breath holds of Wim Hof rounds. Stop for pain, ear symptoms or breathing difficulties. Medical clearance is needed first for airway, lung or heart disease, a previous spontaneous pneumothorax, recent surgery or other relevant conditions.
Who may find it useful? Athletes who specifically want to train their inspiratory muscles and are looking for a separate programme.
Who does not need it? Anyone who only wants to learn the Wim Hof breathing technique.

Which tool would I choose first?
For a complete beginner: none. Begin with a safe breathing position and a short cold shower finish.
If you later plan a cold bath, a simple water thermometer is the most practical first purchase. The Polar H10 is the most useful option for structured heart-rate and HRV tracking. A pulse oximeter is more of an observation device with clear measurement limitations. An inspiratory muscle trainer serves a separate training purpose and should be bought only for that specific goal.
Who should not try the method without medical advice?
The official Wim Hof website advises against starting independently, or requires prior medical consultation, for conditions including coronary heart disease, heart failure or previous stroke, epilepsy, kidney failure, cold urticaria, type II Raynaud's syndrome, hypertension treated with medication, recent surgery and other serious conditions.
The method is not recommended during pregnancy. People with migraine should be especially cautious with ice baths. For those under 16, the breathing exercise is not suitable as an unsupervised routine because of possible light-headedness or loss of consciousness.
Even without a known condition, anyone with unexplained previous fainting, heart rhythm disturbances, chest pain, unusual breathlessness or neurological symptoms should not begin independently.
Common mistakes
- Treating breath holds as records: Longer times are not a reliable measure of progress.
- Combining the breathing exercise with water: The special technique has no place in a shower, bath, pool or open water.
- Starting straight with an ice bath: Adaptation starts with brief, controlled cold exposure.
- Forcing bodily reactions: Strong tingling, dizziness and shivering are not medals.
- Using devices as clearance: Good readings do not rule out risk; unusual readings do not replace diagnosis.
- Taking a cold bath after hard strength training every day: Research on cold-water immersion suggests that regular intensive use immediately after strength training may blunt desired adaptations. This mainly concerns immersion and cannot automatically be applied to a brief shower.
- Selling the method as therapy: Breathing and cold training do not replace medical treatment.
Frequently asked questions
Do I have to practise in the morning on an empty stomach?
The official method often recommends morning practice or an empty stomach. A safe place and feeling steady matter more than the time. Do not practise immediately after a large meal, under the influence of alcohol or drugs, or when ill, very exhausted or dehydrated.
Does the cold shower have to follow the breathing immediately?
No. The two elements can be separated in time. Before entering the shower, you must be breathing completely normally again, fully alert and able to stand securely.
Can a pulse oximeter make the breathing exercise safe?
No. It estimates SpO₂ and pulse, may respond slowly and can be inaccurate with cold or poorly perfused fingers, among other conditions. It does not detect every dangerous situation or prevent fainting.
How often should a beginner practise?
Start with two to four calm sessions per week. If you tolerate everything well, you can practise more regularly. Skipping a session is more sensible than training despite illness, sleep shortage or clear discomfort.
Does the Wim Hof Method “strengthen” the immune system?
That blanket claim is not justified. Small studies show that trained people can influence certain stress and inflammatory responses. This proves neither general protection from infections nor treatment of existing disease.
Conclusion
The Wim Hof Method is not a miracle formula, but neither is it purely imagined. Intensive breathing and cold produce real, measurable responses. The size of any long-term benefit for health, recovery or performance nevertheless remains uncertain given the current evidence.
A sensible introduction is unspectacular: two or three breathing rounds while safely lying down, brief cold shower finishes and slow progression without records. Devices are optional. To dose a later cold bath more objectively, a water thermometer is enough. Pulse oximeters and chest straps provide interesting data but must never encourage you to ignore warning signs. An inspiratory muscle trainer has a separate goal and is not part of the method itself.
Safety beats intensity — in every round and every contact with cold water.
