Why I Never Use Evidence-Based Yoga in My Teaching Marketing
There is an expression I encounter increasingly often in contemporary yoga education: evidence-based yoga.
It appears on websites, teacher-training advertisements, social-media biographies and course descriptions. It suggests credibility, intellectual sophistication and an approach supposedly distinguished from traditional or less informed forms of yoga.
Yet despite my considerable interest in anatomy, physiology, biomechanics and scientific research, Evidence-Based Yoga is not a label I choose to use when marketing my teaching.
Not because I reject science. Actually, quite the opposite.
I question the expression precisely because I take scientific enquiry seriously. A scientific claim should survive scrutiny. Its methodology, assumptions, limitations and conclusions should be open to examination. Where findings remain incomplete or contradictory, the strength of our assertions should reflect that uncertainty.
But yoga is not simply a collection of physiological interventions awaiting scientific validation. It is also an experiential, philosophical and, for many practitioners, spiritual path concerned with the nature of human existence.
When we describe the entirety of yoga as evidence-based, what exactly are we claiming has been established?
That a particular breathing practice affects respiratory function? That a sequence improves mobility? That meditation may influence psychological outcomes? Or that yoga's understanding of karma, saṃskāra, rebirth, liberation and consciousness has been scientifically demonstrated?
Those are very different propositions. And the distinction is fundamental to how I understand and teach yoga.
Evidence-Based Yoga: Why the Language Deserves More Scrutiny
The expression evidence-based has an established history within healthcare. In 1996, David Sackett and colleagues described evidence-based medicine as an approach integrating research evidence with clinical expertise and individual circumstances.
It was never intended to mean that published research should mechanically replace professional judgement. Nor did it mean that a conclusion automatically became universally applicable because a randomised controlled trial reported a statistically significant result.
Evidence must be interpreted. Study populations, research, comparators matter. But so do the outcomes investigated and the circumstances in which findings are applied.
Within contemporary yoga marketing, however, evidence-based can become something rather different. It can function as a rhetorical marker of authority.
The words suggest that a practice has moved beyond uncertainty into established scientific legitimacy. Yet the phrase often appears without specifying which component of yoga has been investigated, what evidence supports it or how confidently the findings can be generalised.
Evidence-based should describe a disciplined relationship with research. It should not become an advertisement for certainty.
Why Evidence-Based Yoga Cannot Be Judged Through One Scientific Lens
One of my concerns is the increasingly narrow interpretation of what counts as legitimate knowledge.
Contemporary experimental science is particularly powerful when investigating observable phenomena and testing relationships between measurable variables.
Anatomical research can investigate skeletal morphology. Biomechanics can examine forces and movement. Physiology can investigate respiratory, cardiovascular and neurological processes. Clinical trials can estimate the effects of defined interventions on particular outcomes. These investigations are indispensable when yoga educators make empirical claims about the human body.
But not every question in yoga belongs to the same category. Philosophy asks questions about knowledge, existence, reasoning, ethics and the nature of experience. Psychology examines cognition, perception, behaviour and subjective processes. Sociology investigates how institutions, cultural expectations, social relationships and forms of authority influence human experience. History and textual scholarship help us understand how yogic concepts emerged, developed and were interpreted within different traditions.
None of these disciplines should be treated as an automatic substitute for another. Equally, it would be mistaken to suggest that scientific research cannot incorporate philosophical reasoning, qualitative investigation or sociological perspectives. Good interdisciplinary research already does.
My criticism concerns the reduction of yoga to a narrow collection of physiological outcomes, followed by the claim that this constitutes a complete scientific account of the practice.
If a claim appears convincing only when examined through one restricted framework, while significant questions remain unanswered from other relevant perspectives, I consider that claim insufficiently developed for universal promotion.
This is not a demand that every field must agree before anything can be known. It is a demand that the conclusion should never exceed the evidence or the scope of the question investigated.
What Does Contemporary Research Actually Establish About Yoga?
The scientific literature on yoga is growing, but growth in publication volume should not be confused with uniform certainty.
A 2026 evidence map commissioned by the United States Department of Veterans Affairs reviewed systematic evidence on yoga for a range of adult physical and mental health conditions. It identified potentially beneficial effects for selected outcomes.
However, high-certainty conclusions were not identified across the mapped conditions and outcomes. Many findings were based on low- or very-low-certainty evidence. The review also noted substantial variation in yoga interventions, including differences in practice type, frequency, duration and reporting quality. These distinctions matter enormously.
A trial investigating posture-based yoga for chronic lower-back pain cannot automatically establish the effects of Yoga Nidrā, Prāṇāyāma, meditation or an entirely different practice. Nor can findings concerning pain, sleep or emotional wellbeing establish the metaphysical propositions of classical yoga.
Yet we frequently encounter statements that yoga has been scientifically proven, as though the term yoga refers to one standardised intervention producing one universally predictable outcome.
The question should always be more specific. Which practice? Which population? Which outcome? Compared with what? And with what degree of certainty?
The presence of scientific research on yoga is not equivalent to comprehensive scientific confirmation of yoga itself.
The Problem of Treating Average Outcomes as Universal Human Experience
Yoga is experiential. Two people can participate in the same practice, follow the same instructions and reach markedly different conclusions about what they experienced.
One student may find a supported posture deeply comfortable. Another may experience discomfort or restlessness. A third may notice little of particular significance.
Even when the physical arrangement is similar, the subjective experience may differ. Physiology matters here, but so do previous experiences, expectations, attention, psychological responses, social circumstances and the interpretation given to bodily sensations.
Research frequently reports average differences between groups. Those averages may be useful for answering carefully defined questions. They do not establish that every individual will respond in the same way. This is why applying population-level evidence requires judgement.
The Medical Research Council's 2021 framework for evaluating complex interventions places considerable emphasis on context, implementation and the mechanisms through which interventions may produce outcomes.
Yoga teaching is precisely the kind of setting in which context matters. An intervention studied among healthy university students may not have identical effects among older adults, people living with chronic conditions or practitioners with extensive movement histories.
Scientific research can investigate these differences. But teachers should not erase them in the name of evidence-based certainty.
Saṃskāra and the Individuality of Yogic Experience
Indian yogic philosophy offers another perspective on why experience and interpretation vary.
Within the Yoga Sūtra tradition, saṃskāra refers to latent impressions or dispositions shaped through experience and activity. The term operates within a broader philosophical account of mind, karma and continuity. It should not be casually equated with neural pathways, psychological conditioning or stored trauma, although carefully qualified comparisons may be explored.
Consider two practitioners sitting in meditation. Both receive the same instruction to observe the breath. One experiences an increasing sense of steadiness. Another encounters persistent memories, desires, irritation or distraction. A third may interpret the practice through an entirely different religious or philosophical worldview.
Their experiences cannot be assumed to be identical simply because the external method is identical. From a yogic perspective, saṃskāra offers one traditional framework for considering differences in mental tendencies and dispositions. Modern psychology may investigate relevant phenomena through learning, memory, attention and individual differences. But these are not interchangeable explanatory systems.
The same practice need not produce the same subjective experience, and different experiences do not automatically establish that one practitioner is succeeding while another is failing.
This is particularly important when teachers make promises about emotional release, nervous-system regulation or spiritual transformation.
Evidence-Based Yoga and the Question of Karma, Rebirth and Liberation
Yoga cannot be understood in its entirety without confronting its deeper philosophical commitments.
The Sanskrit term yoga is commonly associated with the verbal root yuj, often rendered in relation to joining or yoking. However, traditional grammatical and philosophical discussions also distinguish senses associated with concentration or meditative absorption.
It is therefore simplistic to insist that all yoga traditions define yoga exclusively as union. Different Indian traditions have understood yoga's nature and ultimate purpose in different ways.
Within Pātañjala Yoga, kaivalya, or liberation, concerns the distinction between puruṣa and prakṛti.
Within other Hindu traditions, liberation may be understood through different relationships involving the self, consciousness, Īśvara and ultimate reality.
Karma, rebirth and saṃskāra also form part of several traditional philosophical accounts of human existence.
These are not incidental decorative concepts. For many practitioners, they are integral to the reason yoga is undertaken.
Can Science Establish the Final Goal of Yoga?
We can investigate the physiological effects associated with meditation. We can study attention, behaviour, psychological wellbeing and reported spiritual experiences. We can also examine the history and philosophical coherence of traditional accounts. But such research does not establish the existence of rebirth, the operation of karma across lifetimes or the attainment of liberation in the metaphysical sense described by a particular yogic tradition.
These claims are not currently established through contemporary empirical methods. That does not authorise us to declare them scientifically confirmed. Nor does it mean that a person cannot meaningfully engage with them as philosophical or religious commitments.
Within traditions accepting rebirth, the possibility that liberation may unfold beyond a single lifetime forms part of a broader metaphysical worldview. It cannot be converted into a laboratory prediction simply because contemporary yoga education prefers scientific terminology.
If liberation is understood as the ultimate purpose of a yogic path, a study demonstrating reduced blood pressure does not establish that the practitioner has moved closer to liberation.
The study may provide useful information about blood pressure. That is what it measured.
Why Philosophy and Sociology Matter to Evidence-Based Yoga Claims
There is another question I rarely see addressed in yoga marketing. Who decides which outcomes make yoga valuable? Why are flexibility, stress reduction, productivity, emotional wellbeing and physical performance so frequently presented as yoga's defining achievements? These objectives may be useful, but they also reflect contemporary cultural priorities.
Sociology encourages us to examine how institutions and markets shape the language through which knowledge is presented. A yoga programme described as evidence-based may appear more credible within contemporary wellness and healthcare markets. Scientific terminology can function as a form of cultural authority. That authority may be deserved when claims are appropriately supported.
But it can also be borrowed to promote conclusions that the underlying research does not justify. Philosophy asks us to examine the assumptions hidden within the argument. What is being defined as progress? Why is a measurable outcome considered more important than an ethical or contemplative objective? Does the research answer the question we believe it answers? I am particularly wary when a practice's value is reduced to what can be marketed most easily.
Yoga does not become more intellectually sophisticated when its philosophical dimensions disappear behind physiological terminology.
Fascia, Hyaluronan and the Appearance of Scientific Certainty
The contemporary fascination with fascia offers a useful example. There is legitimate research examining connective-tissue mechanics, hyaluronan, fascial gliding and mechanotransduction.
Hyaluronan contributes to the properties of extracellular matrices and certain tissue interfaces. Mechanical loading can influence cellular and tissue behaviour. These are worthwhile areas of investigation.
But popular explanations sometimes move considerably beyond those findings. Spiral movements are said to flush hyaluronan. Long-held postures allegedly release fascial adhesions. Particular sequences are described as uniquely effective for tissue hydration.
The problem is not that such mechanisms are impossible to investigate. The problem arises when physiological plausibility is presented as demonstrated fact.
A study identifying hyaluronan within fascial interfaces does not establish that one yoga movement redistributes it more effectively than walking, resistance training or ordinary stretching. Similarly, improved range of motion does not automatically prove that adhesions have been released.
For a fuller examination, read Fascia in Yin Yoga Teacher Training: Evidence and Misconceptions and Fascia and Movement Science: What Makes One Method Special? These will be released over the next week. So, keep your eyes peeled.
These examples will illustrate why I question the promotional use of evidence-based terminology.
Scientific vocabulary can create an appearance of certainty even when the underlying mechanism remains incompletely understood.
Evidence-Based Yoga Does Not Mean Rejecting Tradition or Accepting It Uncritically
I want to be equally clear about the opposite danger. The fact that something appears in a traditional Sanskrit text does not automatically establish its physiological effectiveness or clinical safety.
A traditional claim that a particular practice treats a disease still requires appropriate evidence if it is promoted as a medical intervention. Likewise, an individual's meaningful experience does not demonstrate that the same experience will occur universally.
Traditional authority and personal testimony are not substitutes for controlled research when we are making empirical health claims. But neither should an absence of clinical trials be used to dismiss the entirety of a philosophical or spiritual path.
These forms of enquiry have different purposes and evidential requirements. We need the intellectual maturity to recognise their differences. For me, this is where responsible yoga education begins: not with a declaration that everything has been proved, but with a willingness to distinguish what is known, what is interpreted, what is believed and what remains uncertain.
The Somāntra™ Approach: Developing Discernment Beyond Scientific Marketing
This concern is central to the educational direction of The Yoga Nerds and the Somāntra™ Approach.
Somāntra™ is not founded on the idea that scientific research is irrelevant. It integrates anatomy, biomechanics, physiology and research literacy with Indian yogic philosophy, embodied observation and responsible teaching methodology. But it does not ask students to reduce yoga to one explanatory framework.
Scientific Understanding Without Reductionism
Through structural and movement education, teachers examine skeletal morphology, muscular activity, connective tissues and mechanical loading. They investigate what research demonstrates and recognise where findings remain provisional.
Experience Without Universal Assumption
Restorative Yoga, Yin Yoga, Yoga Nidrā, Meditation and Prāṇāyāma can produce different experiences among different practitioners. Rather than promising identical outcomes, Somāntra™ encourages teachers to observe, adapt and respond to individuals.
Philosophical Literacy Beyond Anatomical Explanation
Students are encouraged to study concepts such as citta, saṃskāra, karma, prāṇa, dhāraṇā and dhyāna within their relevant traditional frameworks. The intention is not to equate these ideas automatically with modern neuroscience or psychology. It is to understand their philosophical significance while developing the ability to examine empirical claims critically.
Teaching as an Exercise in Discernment
At its heart, Somāntra™ encourages educators to ask why they teach something, what evidence supports their interpretation and whether the practice is appropriate for the person in front of them.
The wider 300-Hour Somāntra™ Yoga Teacher Training provides a modular pathway through Nervous System Sovereignty, Structural and Energetic Integration, and Subtle Body Literacy and Facilitation. The optional Sound Healing component extends the wider educational pathway to 350 hours.
These subjects are studied not as isolated techniques, but as opportunities to deepen anatomical understanding, contemplative enquiry and teaching judgement.

Whether studying Yin Yoga, Restorative Yoga, Yoga Nidrā, Prāṇāyāma or Meditation, the emphasis remains on understanding rather than reproducing unquestioned explanations.
Five Frequently Asked Questions About Evidence-Based Yoga
Is Evidence-Based Yoga Scientifically Proven?
There is research supporting specific yoga interventions for selected outcomes. However, the overall evidence varies in quality, and findings cannot automatically be generalised to every yoga practice or philosophical objective.
Why Avoid Evidence-Based Yoga as a Marketing Label?
Because the expression can imply broader scientific certainty than the available evidence supports. I prefer to describe specific research findings and acknowledge their limitations rather than apply one encompassing scientific label to yoga.
Can Science Explain Saṃskāra, Karma and Liberation?
Science can investigate related psychological, behavioural and reported experiential phenomena. However, traditional metaphysical claims concerning karma across lifetimes, rebirth and liberation are not established by contemporary empirical research.
Does This Mean Yoga Teachers Should Ignore Scientific Research?
No. Anatomy, biomechanics, physiology and clinical evidence are essential when making empirical claims about the body, health and safety. The issue is how evidence is interpreted and how far conclusions are extended.
What Makes the Somāntra™ Approach Different?
Somāntra™ integrates scientific literacy, anatomical understanding, embodied observation and Indian yogic philosophy without treating any one framework as a complete explanation of human experience.
Conclusion: Why I Never Use Evidence-Based Yoga as a Marketing Identity
I value scientific research. I want yoga teachers to understand the body, investigate physiological mechanisms and evaluate claims responsibly. But I do not believe that the entirety of yoga can be appropriately represented through the marketing language of Evidence-Based Yoga.
Yoga is not simply a method for improving flexibility, reducing stress or influencing measurable physiological processes. It is also a philosophical and experiential path through which different practitioners may understand themselves and their existence in profoundly different ways.
Within traditional frameworks, its objectives can extend towards liberation, involving concepts of karma, saṃskāra and continuity beyond a single lifetime. Those commitments cannot honestly be described as scientifically demonstrated. Nor should they be casually dismissed because they do not fit the methodology of a clinical trial.
My position is therefore neither anti-science nor uncritical traditionalism. It is a commitment to intellectual discernment.
Where evidence is incomplete, I will not market certainty. Where a claim is philosophical, I will not disguise it as physiology. And where a scientific conclusion is established, I will not reject it merely because it challenges an inherited belief.
That is the educational direction of Somāntra™.
Through 300-Hour Somāntra™ Yoga Teacher Training near Edinburgh, Scotland and online, The Yoga Nerds invites teachers to study the body scientifically, explore yoga's philosophical foundations and develop the confidence to distinguish knowledge from assumption.
Because advanced yoga education should not simply teach us what to believe. It should cultivate the discernment to understand why we believe it—and where our certainty must end.
