Langsames Atmen und die Wim-Hof-Methode sind gegensätzliche Praktiken. Langsames, kohärentes Atmen mit etwa sechs Atemzügen pro Minute beruhigt das Nervensystem: Es erhöht die Herzratenvariabilität, senkt den Blutdruck sofort und verbessert den Schlaf bei sehr geringem Risiko. Die Wim-Hof-Methode nutzt schnelles zyklisches Atmen, Atemanhaltungen und Kälte, um Adrenalin und Wachsamkeit zu steigern, mit einer kurzfristigen Wirkung auf die Immunantwort.
Eine feste Regel gilt: Das schnelle Atmen bleibt an Land, da es vor einer Atemanhaltung zu einem Blackout führen kann. Im direkten Vergleich hinsichtlich der Stimmungslage schnitten beide Methoden etwa gleich ab; die Wahl hängt also vom gewünschten Zustand und davon ab, welche Methode man langfristig beibehalten wird.
Findings & Outcomes
⚠ Safety: the Wim Hof breathing belongs on dry land. See Cautions.
How They Compare
What Each Does To Your Physiology
Slow breathing works by resonance. At about six breaths a minute the breath synchronizes with the baroreflex, the roughly five-second loop that adjusts heart rate to changes in blood pressure. The two rhythms reinforce each other, the heart rate swings wide, and the calming, parasympathetic branch of the nervous system dominates. That coupling peaks near six a minute and fades as the rate climbs toward a normal 12 to 16. The shared mechanism is set out on resonance and entrainment, and the practice with its protocol on breathwork and HRV.
The Wim Hof Method drives the reverse state. Rounds of forced fast breathing lower carbon dioxide into respiratory alkalosis, and the breath holds add brief drops in oxygen. The combination produces a surge of adrenaline, a sympathetic, aroused state. Brain scans of the method (Muzik 2018) point to a driver in the brain, not just a peripheral reflex. Those control centers dull how strongly cold is felt and hold attention steady under a harsh stimulus. The two practices move the nervous system in opposite directions.
Anxiety And Stress
A systematic review of slow breathing in healthy people found it reliably shifts them toward calm, less anxiety, arousal, and low mood, with a rise in heart rate variability. One trial pitted the two directly against each other in 84 women with high stress and depressive symptoms. Over three weeks both produced about equal reductions: depressive symptoms down roughly 24 percent, anxiety about 27 percent, and perceived stress about 20 percent, all sustained at three months.
The Wim Hof arm showed one edge, a bigger drop in rumination after stressful days. The authors caution that it needs repeating before it can be trusted: all six dropouts came from that arm, and participants rated the slow-breathing control as more credible.
Blood Pressure And Heart Rate Variability
Slow breathing has the clearer claim here. In people with high blood pressure, breathing at six a minute dropped systolic pressure from about 150 to 141 mmHg on the spot, and nearly doubled baroreflex sensitivity. That in-session drop is a free, self-directed lever, worth trying before a first blood-pressure prescription. Practiced near the resonance rate, usually with HRV biofeedback, it pushes heart rate variability up. That yields a small-to-moderate benefit for stress and anxiety, one of its bigger measured effects. The long-term picture from daily home practice is weaker. A pooled analysis of device-guided breathing found no significant lasting reduction in blood pressure, so the strongest evidence is the immediate in-session drop.
The Wim Hof Method is not a blood-pressure practice. Its active phase raises the body's arousal and briefly raises blood pressure, whereas slow breathing lowers it.
Energy And The Immune Response
The most distinctive Wim Hof finding is short-lived and involves the immune system. Trained volunteers raised adrenaline enough to blunt the inflammatory response to an injected bacterial toxin. They showed more of the anti-inflammatory signal IL-10, less of the pro-inflammatory TNF, IL-6, and IL-8, and fewer flu-like symptoms. The effect repeats in other trials, and it appears only against that kind of sudden immune challenge.
The wider claims for lasting energy and focus are less settled. The performance trials so far are small, often 10 to 40 people, and their results are mixed. No study has shown the boost people feel is more than the placebo effect plus the method's strong appeal. Slow breathing makes no comparable immune claim; what it has been shown to do is calm the nerves, improve sleep, and lower blood pressure.
The Safety Split
The two are not equally risky. Slow, quiet breathing is very low risk and suits nearly everyone. The Wim Hof breathing runs three or four rounds of about 30 rapid breaths, each capped by a breath hold. That combination carries one specific hazard around water, set out under Cautions.
In water it can be fatal, so keep the fast breathing and any breath hold away from the pool, the bath and open water.

Mood & stress
Slow breathing leaves people calmer and less anxious
Breathing slowly, under about ten breaths a minute, moves the nervous system toward its calm setting and leaves people feeling steadier, with less anxiety and less arousal.
A systematic review of fifteen studies in healthy people, drawn from an initial pool of 2,461 abstracts, found slow breathing techniques consistently raise heart rate variability and respiratory sinus arrhythmia, mark a rise in EEG alpha and a fall in theta, and pair with self-reported gains in comfort, vigor and alertness and drops in anxiety, anger, depression and confusion. The review reports a direction of effect, not a single pooled number, so the size varies with the technique and how long it is practiced.

Im direkten Vergleich linderten die beiden bei 84 Frauen Depression, Angst und Stress etwa gleich stark
Als die beiden gegeneinander getestet wurden, linderten sie Depression, Angst und Stress etwa gleich stark, und beide Effekte hielten drei Monate an; die Wim-Hof-Gruppe grübelte nach stressigen Tagen etwas weniger.
Eine randomisierte kontrollierte Studie teilte 84 Frauen mittleren Alters mit hohem Stress und starken depressiven Symptomen entweder einer Wim-Hof-Methode-Bedingung (intermittierende Hypoxie-Atmung plus kalte Duschen) oder einer aktiven Kontrolle (langsame, getaktete Atmung plus warme Duschen) zu, jeweils mit 15 Minuten täglicher Audioanleitung über drei Wochen. Beide Gruppen verbesserten sich gleichermaßen: Depressive Symptome sanken um etwa 24 Prozent, Angst um etwa 27 Prozent und wahrgenommener Stress um etwa 20 Prozent, anhaltend nach drei Monaten, mit vergleichbaren Rückgängen der Cortisol-Reaktivität auf einen Laborstressor. Der Wim-Hof-Arm zeigte eine stärkere Verringerung des Grübelns nach täglichen Stressoren, ein Befund, der laut den Autoren einer Replikation bedarf. Alle sechs Studienabbrecher stammten aus dem Wim-Hof-Arm, und die Teilnehmenden bewerteten die langsame Atem-Kontrolle als glaubwürdiger.
Who this may not transfer to:Tested only in midlife women with high stress and depressive symptoms, so whether the two practices stay equivalent in men, or in people without these symptoms, is untested.
Da die beiden die Stimmung gleichermaßen verbesserten, ist die praktische Wahl nicht, welche für die Stimmung besser wirkt, sondern welchen Zustand Sie anstreben und welche Praxis Sie tatsächlich beibehalten werden: langsame Atmung für Ruhe und Erholung, die Wim-Hof-Variante für eine stimulierende Herausforderung, vom Wasser ferngehalten.

Heart And Vascular
Breathing at six a minute drops systolic pressure from about 150 to 141 mmHg on the spot
Slowing the breath to about six a minute drops blood pressure while you do it, by roughly nine points on the top number in people with high blood pressure.
In a controlled laboratory study of 20 people with essential hypertension and 26 controls, breathing at six breaths a minute reduced systolic pressure from 149.7 to 141.1 mmHg and diastolic from 82.7 to 77.8 mmHg, and raised arterial baroreflex sensitivity from 5.8 to 10.3 ms/mmHg, all measured on the spot without inducing hyperventilation. The lasting effect of home practice is less settled: a meta-analysis of 22 trials in 17,214 people found device-guided slow breathing did not significantly reduce blood pressure over time, with high heterogeneity between studies, so the strongest evidence is for the immediate in-session drop, not a large chronic change.
Who this may not transfer to:The study does not report its results split by sex, so whether the size of the blood-pressure drop differs for women and men is untested.

Anxiety And Stress
Slow breathing near six a minute drives heart rate variability up and eases anxiety
Practicing slow breathing near six a minute swings the heart rate into big smooth waves and gives a small to moderate drop in stress and anxiety, which is one of its strongest measured effects.
A systematic review and meta-analysis pooling 58 randomized studies found heart rate variability biofeedback, which trains breathing near each person's resonance rate, produced small to moderate improvements across stress, anxiety and related outcomes, with anxiety among the larger effects. The authors note the number of studies per condition is small and call for confirmation. The mechanism is separate physiological work, not part of the pooled trials.
Who this may not transfer to:The meta-analysis does not report participant sex, so any difference in the effect between women and men is untested.

How it works
Slow breathing at six a minute resonates with the baroreflex and settles the nervous system
Breathing at about six a minute lines up with the body's blood-pressure control loop, which is why the heart rate swings wide and the nervous system settles.
The baroreflex takes about five seconds to complete a cycle, giving it a natural frequency near 0.1 Hz, which is six cycles a minute. Breathing at that rate couples the breathing rhythm to the pressure-control loop so the two reinforce each other, driving heart-rate oscillations far larger than at rest and raising baroreflex gain. This is a mechanism of resonance and parasympathetic engagement, the opposite direction of travel from a practice built on arousal. The shared physiology behind it is set out on the resonance and entrainment page.

Die Wim-Hof-Methode treibt durch schnelle Atmung, Atempausen und Kälte einen erregten, sympathischen Zustand an
Die Wim-Hof-Methode nutzt schnelle forcierte Atmung, Atempausen und Kälte, um den Körper in einen erregten, stimulierten Zustand zu versetzen, was das Gegenteil dessen ist, was langsame Atmung bewirkt.
Die Gehirnbildgebung des Begründers der Methode neben einer Kontrollgruppe fand, dass die Praxis das periaquäduktale Grau aktiviert, ein Kontrollzentrum für absteigende Schmerz- und Kältesignale, das eine stressinduzierte analgetische Reaktion auslösen kann, sowie höhere Insula-Regionen, die mit fokussierter Aufmerksamkeit unter aversivem Reiz verbunden sind. Eine Ganzkörper-PET während Kälte fand, dass forcierte Atmung die sympathische Aktivität und die Wärmeproduktion in den Interkostalmuskeln erhöhte, während die Aktivierung des braunen Fettgewebes unauffällig blieb. Die Autoren deuten dies als Beleg dafür, dass eher das Gehirn als die Peripherie die Kältetoleranz antreibt. Die zentrale Bildgebung beruht auf einem einzelnen Praktizierenden, sie beschreibt also einen plausiblen Mechanismus, keine Tatsache auf Gruppenebene.

Sleep
Twenty minutes of slow breathing before bed helped insomniacs fall asleep faster
Doing about twenty minutes of slow breathing before bed helped people with insomnia fall asleep faster and wake up less during the night.
In einer kontrollierten Studie mit 14 selbstberichteten Schlaflosen und 14 guten Schläfern zeigten die Schlaflosen zu Studienbeginn eine verringerte hochfrequente (vagale) Herzfrequenzvariabilität. Die Praxis langsamer, getakteter Atmung mit 0.1 Hz für 20 Minuten vor dem Schlafen erhöhte die gesamte Herzfrequenzvariabilität und verkürzte in der Polysomnografie die Einschlaflatenz, verringerte Anzahl und Dauer der Aufwachphasen und erhöhte die Schlafeffizienz. Es ist eine kleine frühe Studie, der Effekt gilt also als aufkommend, nicht als geklärt.

Immune Function
Wim-Hof-Training ermöglichte es 12 Freiwilligen, die Entzündungsreaktion auf ein injiziertes Toxin abzuschwächen
In der Methode geschulte Menschen setzten einen Adrenalinschub frei, der die Entzündungsreaktion des Körpers auf ein injiziertes bakterielles Toxin dämpfte, und sie verspürten weniger grippeähnliche Symptome.
In einer randomisierten Studie wurden 12 gesunde Freiwillige zehn Tage lang in Meditation, zyklischer Hyperventilation gefolgt von Atemanhalten und Kälteexposition geschult, während 12 Kontrollpersonen dies nicht wurden. Alle erhielten anschließend intravenöses E.-coli-Endotoxin. Die Praxis der Techniken erzeugte intermittierende respiratorische Alkalose und Hypoxie und erhöhte das Plasma-Adrenalin deutlich, was mit einem schnelleren und höheren Anstieg des entzündungshemmenden Zytokins IL-10 sowie mit niedrigeren Werten der proentzündlichen Mediatoren TNF, IL-6 und IL-8 korrelierte, plus weniger grippeähnlichen Symptomen. Es ist eine einzelne kleine Studie in einer Laborprovokation, sie zeigt also einen akuten Mechanismus, keine erwiesene Behandlung für irgendeine entzündliche Erkrankung.

Cognition
Das eindeutigste Signal der Wim-Hof-Methode ist geringere Entzündung, nicht die von Anhängern beschriebene Energie und Konzentration
Die von Anhängern beschriebene Energie und Konzentration sind noch nicht belegt: Die Studien weisen am eindeutigsten auf einen kurzfristigen Entzündungseffekt hin, während die Leistungsergebnisse gemischt sind.
Eine systematische, nach PRISMA durchgeführte Übersichtsarbeit identifizierte neun Arbeiten zu acht Studien der vollständigen Methode. Der konsistenteste Befund war die verringerte Entzündung, angetrieben durch den Adrenalinschub, der IL-10 erhöht und proentzündliche Zytokine senkt. Die Effekte auf die sportliche Leistung waren gemischt, ebenso die Effekte auf Atemwerte wie Atemminutenvolumen und Atemzugvolumen nach Belastungsphasen. Die Übersichtsarbeit fordert weitere Forschung bei Menschen mit entzündlichen Erkrankungen. Die von Praktizierenden berichtete subjektive Energie und Konzentration wurde nicht von Erwartung und der starken Anziehungskraft der Methode und ihres Lehrers isoliert.

When To Choose Which
Choose slow breathing, near six a minute, when you want to come down. It costs nothing, needs only a clock, and carries almost no risk, so it is the default for:
- anxiety and everyday nervous-system balance,
- winding down toward sleep,
- lowering blood pressure in the moment,
- a daily habit of steadying yourself.
Choose the Wim Hof Method when you want a stimulating challenge: a jolt of morning alertness, cold adaptation, or its short-term immune and adrenaline effects. Treat it as the arousal practice it is, keep the fast breathing on dry land and off the road, and build up slowly. Many people use both, slow breathing in the evening to recover and settle, the Wim Hof style earlier in the day for a deliberate charge.
Go Deeper
- Breathwork and HRV: the slow-breathing practice in full, with the protocol and what a heart rate variability reading means.
- Resonance and entrainment: the mechanism behind the heart-breath coupling both practices touch.
- Cold exposure: the cold half of the Wim Hof Method, on its own terms.
- Anxiety: where slow breathing sits among the things that help, at its measured size.
- Insomnia: where a pre-sleep breathing habit fits among the things that improve sleep.
Cautions
Extra restraintEverything to be aware of is here, in one place. This practice suits most healthy people; a few situations call for real care.
Schnelles Atmen vor dem Luftanhalten im Wasser kann einen tödlichen Bewusstseinsverlust unter Wasser verursachen
Eine Fallübersicht des Staates New York zu Ertrinkungsfällen von 1988 bis 2011 identifizierte 16 Fälle, die mit dem verbunden waren, was die Autoren als gefährliches Luftanhalten unter Wasser bezeichneten, einschließlich absichtlicher Hyperventilation vor dem Untertauchen; zwei gesunde junge Männer starben bei einem einzigen Vorfall 2011, nachdem sie vor dem Untertauchen hyperventiliert hatten. Der Mechanismus ist der hypoxische Bewusstseinsverlust: Da der Atemreiz durch ansteigendes Kohlendioxid ausgelöst wird, nicht durch fallenden Sauerstoff, verzögert vorheriges Atmen, das Kohlendioxid entfernt, diesen Reiz, bis der Sauerstoff so weit gefallen ist, dass Bewusstlosigkeit eintritt, oft ohne Vorwarnung. An Land ist dies beherrschbar; unter Wasser führt es zum Ertrinken. Deshalb gehören die schnelle zyklische Atmung und jedes Luftanhalten fern vom Pool, der Badewanne und offenem Wasser.Boyd et al. (CDC), fatal and nonfatal drowning outcomes related to dangerous underwater breath-holding behaviors, New York State, 1988-2011
The Wim Hof breathing and water
A round of fast, deep breathing before a breath hold clears out carbon dioxide without adding much oxygen. The urge to breathe comes from rising carbon dioxide, so after that flush it may not arrive until oxygen has dropped far enough to black out, with little warning. On land that is manageable. In water it can be fatal, so keep the fast breathing and any breath hold away from the pool, the bath and open water. Reviews of real drownings, swimmers who over-breathed and then held their breath, are why this is a hard rule.
A second person, on land
Loss of consciousness during heavy breathing or a breath hold can happen even out of the water. Do the Wim Hof breathing sitting or lying on a soft surface, ideally with someone nearby, and never while driving or standing.
Pregnancy
Slow, quiet breathing is fine in pregnancy. Deliberate over-breathing lowers carbon dioxide enough to narrow the vessels feeding the uterus, established obstetric physiology. The forceful cyclic breathing has not been studied in pregnancy, so set it aside.
Heart, epilepsy and other conditions
The forceful breath holds and hyperventilation rounds drive large swings in blood pressure and blood chemistry. If you have uncontrolled high blood pressure, a recent cardiac event, aortic disease or epilepsy, talk to a doctor before taking the Wim Hof Method up. Slow paced breathing at six a minute is the gentle practice studied in these conditions, and is a different matter.
Slow breathing is safe for most
Slow, quiet breathing at about six a minute carries almost no risk for healthy people. If breathing feels like effort, take smaller breaths at the same slow rate, since forcing the volume tips slow breathing into over-breathing.
Start slow, be smart, read the research, and consult a professional if you have any concerns. This is here to inform your choice, not make it for you.
Common Questions
Which one helps with sleep?
Slow breathing. About twenty minutes of slow paced breathing before bed helped people with insomnia fall asleep faster, wake less during the night, and sleep more efficiently. Vagal heart rate variability, the calming side, rose alongside. The Wim Hof Method points the other way, toward arousal, so for sleep the slow, quiet evening version is the one to use.
