There is likely a reason you reach for a particular material when the world becomes difficult. The nervous system is doing functional, physiological work, and the research supports what the body already seems to know.
The relationship between sensory experience and nervous system regulation is well-documented and directly relevant to creative practice, in ways that are almost entirely absent from mainstream creative discourse. Understanding it changes what material choice means, and why certain mediums become important to certain artists in ways that have little to do with aesthetic preference alone.
This piece looks at four places the research clarifies the relationship, and closes with three artists whose changed circumstances made that relationship most visible.

What the Art Materials and Nervous System Research Shows
Stephen Porges’ polyvagal theory describes the nervous system’s movement among three primary states: the ventral vagal state (safe, connected, regulated), the sympathetic state (mobilized, fight-or-flight), and the dorsal vagal state (shutdown, immobilization, collapse). Creative work, in most of its forms, requires something close to the ventral vagal state: a felt sense of safety sufficient to allow real exploration, openness to what emerges, the capacity to stay present with uncertainty.
The pathway to the ventral vagal state is rarely purely cognitive or volitional. Physical and sensory input plays a significant role in shifting the nervous system among states. Kinds of engagement that include repetitive movement, rhythmic action, focused sensory attention, and moderate physical challenge without threat have been documented to support movement toward the ventral vagal state. This is why certain creative materials and practices function as regulation tools for the nervous system rather than only as expressive vehicles. The art materials and nervous system relationship means the material is doing physiological work that the content of the work neither replaces nor replicates.
The philosopher John Dewey, in Art as Experience, argued that the making itself is a continuous correspondence between the artist and the material as it resists and responds. The material is never passive. For the polyvagal-informed artist, Dewey’s point extends: the material is never neutral either. Its sensory qualities reach the nervous system through the hands, the eyes, the ears, the nose. The correspondence Dewey described is always, also, a physiological exchange. Every material has a regulatory profile, named or unnamed.

What Cross-Body Engagement Offers
Some creative materials and practices produce what researchers describe as bilateral or cross-body engagement: activities that require coordinated use of both sides of the body, crossing the body’s midline, with documented neurological effects. Fiber arts, particularly crochet and knitting, are widely studied examples: the coordinated bilateral hand movement, combined with the rhythmic and repetitive nature of the work, produces effects that are distinct from what unilateral or non-repetitive making generates.
The neurological effects of cross-body creative engagement include bilateral stimulation of brain hemispheres, activation of the body’s regulatory systems, reduction in cortisol associated with the arousal response, and support for heart rate variability patterns associated with regulated nervous system states. These effects are measurable and replicable. They are also independent of the quality or meaning of what gets made: the body receives the regulatory benefit of the bilateral repetitive movement whether the work being made is significant or otherwise.
This is the same mechanism the polyvagal research names, now made visible in one material family. Bessel van der Kolk’s work on trauma and the body, particularly The Body Keeps the Score, documents the same bilateral principle at work in therapeutic contexts: coordinated cross-midline engagement supports the nervous system’s capacity for integration in ways purely cognitive interventions rarely reach. What happens in the fiber artist’s hands during a difficult week is, at the physiological level, adjacent to what happens in therapeutic bilateral stimulation protocols. Artists with anxiety or hypervigilance often describe certain bilateral creative practices as the only engagement that reliably quiets the internal noise. The benefit is physiological, and it arrives through the sensory and motor engagement the material provides, regardless of what is produced.
What the Body Remembers Across All the Materials It Has Touched
The somatic memory of creative materials, what each medium has felt like under the hands across the full arc of a creative life, persists long after any given practice has ended. Peter Levine’s research on somatic experiencing, the body’s capacity to hold and process experience through physical sensation rather than through narrative, suggests that the body’s relationship with materials it has worked with is stored as felt sense rather than as explicit memory. You may be unable to describe in precise terms what working with a childhood material felt like, and the body holds that information and can access it.
This is why returning to a childhood material during a period of health difficulty often produces an effect that seems disproportionate to the activity: the body is accessing a felt sense of safety and creative capacity from a time before the health challenge existed, through the sensory properties of the material rather than through any cognitive intention. The material is the key. The body holds the door.
Eugene Gendlin, whose work on focusing explored the body’s capacity to carry information that arrives in language only after the body has had time with it, described this carrying as an ongoing somatic process. The body holds. It remembers through sensation. When the hand meets a material it has known before, the meeting surfaces what the body has been keeping. Sensory creative regulation, in this light, includes the regulation available through reunion with material the body has already learned how to be with.
What Dance Illuminates About Embodied Medium and Mental Health
Dance as a medium has a documented relationship with mental health that illuminates what any embodied creative practice offers at the physiological level. Dance/movement therapy research has found consistent effects on depression, anxiety, and trauma responses that are attributed to the qualities of embodied movement: the simultaneous engagement of physical, emotional, and cognitive systems; the experience of self-efficacy through physical action; the regulation of nervous system states through rhythmic movement; and the processing of experience through kinesthetic rather than verbal channels.
What dance demonstrates, for the wider question of art materials and nervous system function, is that the embodied quality of making is doing physiological work that cognitive or verbal creative engagement neither touches nor replaces. The body moving through space, the hands working with resistant material, the breath moving in coordination with physical effort: these are more than means to a creative end. They are part of what the making is providing, at a level that precedes and shapes the quality of creative engagement available.
Pat Ogden’s sensorimotor psychotherapy builds on the same recognition from a therapeutic angle. The body is an organ of knowing. Movement, posture, breath, and sensation are all places the nervous system speaks, and they all participate in the state from which any cognitive or creative work becomes possible. Dance, in her frame, is one of the clearest illustrations of what every embodied art is also doing, at some level, through the sensory vocabulary each material offers.
What Matisse, Chuck Close, and Others Demonstrate
Henri Matisse’s cut-paper works of the 1940s were developed after severe illness made painting physically impossible. Working with pre-painted sheets of paper and scissors from a wheelchair, Matisse developed a new sensory relationship with his material: the direct manipulation of flat color, the physical encounter with large sheets, the scissors as a drawing tool. The cut papers have qualities the paintings lack in the same way: a flatness, a directness, a relationship between figure and field that emerged from the sensory and procedural demands of the new method. Matisse described them as the pinnacle of his work. The constrained medium produced a new art materials and nervous system relationship, and the new relationship produced work the unconstrained practice could never have arrived at.
Chuck Close, following a spinal artery collapse in 1988 that left him largely paralyzed, continued making large-scale portraits using a brush strapped to his wrist and a grid system that broke each portrait into individually painted cells. The grid method was developed around what the changed body could do: the limited range of motion, the constrained fine motor capacity. What it also produced was a different quality of sensory engagement with the work: iterative attention to each mark, a physical relationship with the image at the scale of the cell rather than the scale of the whole canvas. Close has described this as a more intimate relationship with the making than the previous method had produced.
Louise Bourgeois, in the last decades of her long life, turned to fabric sculpture and stitched cloth works made from the household textiles of her mother’s tapestry-restoration shop. The material carried memory Bourgeois had been processing her whole career, and the physical engagement with cloth, needle, and thread produced a body of work as expressively charged as her bronze and marble sculpture, with a wholly different sensory register. The nervous system meeting fabric in her aging body was doing work the hard materials could no longer do in the same way.
Rosemarie Garland-Thomson’s misfitting framework sits behind all three examples. The changed body, meeting a medium or a set of tools built for different capacities, produces friction. The friction forces attention. The attention, in turn, opens the possibility of a new sensory relationship with material that the fitted body never had occasion to build. What Matisse, Close, and Bourgeois make legible is that the art materials and nervous system relationship is most visible at the point where the old fit has broken and the new fit is being found.
When the Sensory Relationship Reverses
The research on art materials and nervous system regulation tends to focus on the regulating direction: the material that calms, the bilateral rhythm that quiets the internal noise, the medium that reliably delivers the maker back to themselves. This is the direction most worth documenting, because it is the least visible in mainstream creative discourse.
The other direction exists too, though.
A health change, a trauma, a medication shift, a period of sustained high stress, or the accumulation of difficult associations with a medium can reverse the sensory relationship entirely. The material that once regulated begins to activate. The fiber practice that reliably produced calm starts producing agitation instead. The studio that used to feel like safety starts feeling like demand. The hands that knew what to do in the familiar medium no longer recognize what they are touching.
This reversal is disorienting in a way that is hard to articulate, partly because the cultural script for craft and making runs almost entirely in the regulating direction. Knitting is supposed to calm you. Crochet is supposed to help. When it stops doing that, the maker tends to conclude that something has gone wrong with them rather than that the sensory relationship between their changed nervous system and a familiar material has shifted and needs to be renegotiated.
Peter Levine’s work on somatic experiencing is useful here. The body holds the history of what a material has meant, and a material that acquired difficult associations during a hard period carries those associations into every subsequent session. The hands pick up the familiar yarn and the nervous system reads the memory stored in that texture before any conscious intention arrives. The maker may have no idea why the beloved medium now feels wrong. The body knows before the mind does, and the body is reporting accurately.
The misfitting framework Rosemarie Garland-Thomson offers applies in this direction as well. The changed nervous system meeting a medium built for an earlier version of the maker’s body produces friction. The friction is information. It is asking the maker to pay attention to what the sensory relationship has become rather than what it used to be, to read the current fit rather than insisting on the remembered one.
This does not always mean leaving the medium. Sometimes the reversal is temporary and the relationship restores itself as the nervous system stabilizes. Sometimes a modification in how the medium is used, the scale, the pace, the setting, the time of day, resolves the dysregulation. Sometimes a different medium entirely is what the nervous system is asking for, and the maker’s work is to follow that request rather than override it.
What it always means is that the sensory experience of making is worth reading as information rather than managing as a problem. A material that used to help and has stopped helping is not evidence of a broken creative practice. It is evidence of a nervous system that has changed and is reporting honestly on what it now needs. The body keeps the score, as van der Kolk named it. In the studio, that means the hands know things the planning mind has not yet caught up with.

With gratitude for the words you share Martha Bayne, Jane Pike, Costanza Sofia M., Michelle Ogundehin and Rebecca Todd
Thank you Kathryn for such an interesting and somewhat necessary piece for us to consider amongst the excess of noise in the world today, which can have a heavy impact on our nervous systems. There is so much excellent new evidence here and yet this is also backed by further historic stories of artists we know of and love. I did not know that about Matisse and his paper cut work.
As a knitter, I liked the part about the cross body impact from knitting and crochet and also that 'the body is an organ' and senses and recalls things like smells, materials and rhythms used, way before we notice the good effect on us with our brains. This explains why only recently coming to collage in the last few years 'feels' like home and is really settling and quite all consuming for me once I begin. I believe that is because as a child I loved to escape to the safety and sanctuary of cutting and gluing paper from catalogues and magazines into scrapbooks and on to paper etc.
I really like the book Your Brain on Art by Susan Magsamen and Ivy Ross who look at How the Art Transform Us with so much good data and scientific evidence and it is so questionable that as you say, this topic is 'almost entirely absent from mainstream discussions of creative practice'.
