Science: Bioelectricity

What It Is

Bioelectricity is the study of the voltages living tissue generates and uses. Every cell, not just nerve and muscle, holds that membrane voltage, set by ion pumps and channels. It is textbook cell biology and not disputed.

The Established Science

A cell's voltage tracks its stage. Undifferentiated and cancerous cells sit depolarized, toward minus 10 millivolts; mature, fully differentiated cells sit polarized, toward minus 90. That correlation is the observation the modern bioelectric research program is built on. Push a cell to a new voltage and the tissue can follow. In frog embryos, an altered bioelectric state produced complete eyes in the wrong place. In a flatworm, an altered voltage pattern produced a two-headed animal with no change to its genome. Both results are replicated and published in mainstream journals. Michael Levin, whose lab produced them, co-founded Morphoceuticals, a company developing bioelectric therapies.

A cut generates a direct-current field at its wound edge. In human skin it measures about 107 to 148 millivolts per millimeter in young adults, and roughly a third weaker in people over 65. Richard Nuccitelli, who took those human measurements, used a device from his own company, BioElectroMed. In cell culture and in mice, a field of similar strength overrides chemical and contact cues and becomes the main directional signal for cell movement. The human data show the field is present and measurable. The steering itself has been shown only in cells and mice.

Loading bone generates electric potentials at the strained tissue, tied to collagen's piezoelectricity and to fluid moving through the bone. These stress-generated potentials change how bone cells divide and lay down matrix. That is one route by which bone builds where it is loaded. The piezoelectric effect in bone was demonstrated in the 1950s and is not in question. Its precise role in everyday remodeling, and the value of the stimulation devices built from it, are still being worked out.

How it works

Every cell holds a voltage across its membrane, from about minus 10 to minus 90 millivoltsEstablished

In plain terms

Cells generally, not only nerve and muscle, hold a voltage across their membrane, maintained by ion pumps and channels. Values run from around minus 10 millivolts in rapidly dividing and cancerous cells to about minus 90 in mature, fully differentiated ones.

In detail

Cells generally, not only nerve and muscle, hold a voltage across their membrane, maintained by ion pumps and channels. Values run from around minus 10 millivolts in rapidly dividing and cancerous cells to about minus 90 in mature, fully differentiated ones. Measured in: Universal in biology. The spread matters more than the numbers. Cells that have not yet differentiated sit depolarized, and cells that have finished sit polarized, which is the observation the whole bioelectric research program is built on.

Who this may not transfer to:A property of cells across biology, not a finding in one group of people, so it applies universally.

A wound generates an electric field of about 107 to 148 millivolts per millimeter that guides healing cellsEstablished

In plain terms

A cut generates a direct-current field at the wound edge, measured at about 107 to 148 millivolts per millimeter in the skin of young adults, and weakening as it heals. In cell culture and in mice, an applied field of similar strength acts as the dominant directional cue and overrides others.

In detail

Nuccitelli and colleagues (2011) measured the lateral electric field at fresh skin wounds and found roughly 107 to 148 mV/mm in adults aged 18 to 25, weakening as the wound healed and smaller in older skin; a comparable field of about 122 mV/mm was measured in mice. In cell-culture and mouse work (Zhao 2006), an applied field of similar strength steered cell migration more strongly than chemical or contact cues, acting through PI3K-gamma and PTEN. The human data establish that the wound field is real and measurable; the directional-cue mechanism is shown in cells and mice, not in intact people.

Who this may not transfer to:The wound field was measured in adults aged 18 to 80 with the sex not reported, and it runs about a third weaker in people over 65 than in those under 25. The directional-cue mechanism is shown in cells and mice, not in intact people.

Acupuncture points map about 80% onto connective-tissue planes, a proposed physical mechanismEstablished

In plain terms

Langevin and colleagues proposed that rotating a needle winds connective tissue around it and transmits a mechanical signal to fibroblasts, and that this coupling produces the resistance practitioners call needle grasp. Separately, they mapped an 80% correspondence between acupuncture point locations and connective tissue planes in serial sections of the human arm.

Separately, they mapped an 80% correspondence between acupuncture point locations and connective tissue planes in serial sections of the human arm. Measured in: A hypothesis paper drawing on the authors' human and rat work, plus a cadaveric mapping study of the arm. The mechanism paper is framed by its authors as a hypothesis, not a demonstration, and the 80% correspondence is an anatomical correlation in cadaver sections, not evidence of a functional channel. It is a testable physical account of needling that does not require meridians to be conduits.

Who this may not transfer to:The 80% figure comes from postmortem sections of the human arm with sex not reported, and it is an anatomical mapping, not a test in living, treated people.

Bone generates an electric signal under load, part of how it remodels where it is stressedEstablished

In plain terms

Loading bone generates electric potentials at the strained tissue, an effect tied to collagen's piezoelectricity and to fluid movement through bone. These stress-generated potentials alter cell proliferation and matrix production, which is one proposed route by which bone builds where it is loaded. Electrical stimulation devices grew out of this and have been used to help stubborn fractures knit.

These stress-generated potentials alter cell proliferation and matrix production, which is one proposed route by which bone builds where it is loaded. Electrical stimulation devices grew out of this and have been used to help stubborn fractures knit. Measured in: Review of laboratory, animal and device studies of bone bioelectricity. The piezoelectric effect of loaded bone is well established, but its exact role in everyday remodeling and the clinical value of electrical stimulation are still debated, with the review noting uneven trial design and dosing. This card grades the mechanism, not any stimulation product.

Who this may not transfer to:The piezoelectric effect is a material property of bone tissue; the therapeutic stimulation devices are a separate clinical claim that this page does not grade.

Structured or hexagonal water, as sold, is not supportedDebunked

In plain terms

The exclusion zone near strongly hydrophilic surfaces, a layer that repels microspheres, is real and has been independently demonstrated by several groups. What is contested is the explanation: Schurr's diffusiophoresis account competes with Pollack's idea that the water there is structurally different from bulk water, and the reviewers judge the diffusiophoresis explanation the more compelling one.

What is contested is the explanation: Schurr's diffusiophoresis account competes with Pollack's idea that the water there is structurally different from bulk water, and the reviewers judge the diffusiophoresis explanation the more compelling one. Measured in: Physical chemistry, laboratory measurement. The interface phenomenon is well documented and still needs a theoretical explanation, which is a different statement from the one printed on a bottle. That no structuring device has shown a health benefit is our own reading of the absence of trials, not a finding from this review.

Who this may not transfer to:A laboratory interface effect at hydrophilic surfaces, not a persistent property of bottled or filtered water people drink.

What This Has to Do with Acupuncture

The best-supported physical account of acupuncture needling is mechanical. Rotating a needle winds the collagen around it, deforming the connective tissue and signaling the fibroblasts inside it. That is the origin of the sensation practitioners call needle grasp, and it ties needling to the fascial planes that channels partially follow. In serial sections of the human arm, one group mapped an 80% correspondence between acupuncture point locations and connective-tissue planes, and framed it as a hypothesis.

That cadaver mapping proposes a partial mechanism; it does not show that acupuncture treats any given condition, and it holds whether or not meridians conduct anything. Electrical skin-impedance studies at those points are their own question: they exist, most are low quality, and the results are contested. The stronger claim, that meridians are literal anatomical ducts, has not been replicated.

Where the Claims Stop

The same vocabulary (voltage, field, frequency) is used to market claims that fail testing.

Structured, hexagonal or exclusion-zone water, as sold. The exclusion zone, a narrow layer at strongly hydrophilic surfaces that repels microspheres, is a laboratory effect several groups have reproduced. Its explanation is contested among physical chemists, with a diffusiophoresis account competing against the idea that the water there is structurally different. The consumer product makes a different claim, and it fails: bulk water reorganizes its hydrogen-bond network in trillionths of a second. Bulk water holds no lasting structured phase, and no structuring device has demonstrated a health benefit in testing.

Water crystals shaped by intention. The famous photographs came from a procedure with no blinding. The photographer knew each sample's label, and a few attractive crystals were picked from thousands. That does not show intention restructures water.

Detectable healing biofields. Electromagnetic fields around the body exist and are measured routinely, for instance in an ECG. The claim that a practitioner can sense and manipulate a single coherent field is different. Tested under blinded conditions, practitioners could not detect a human energy field better than chance. Where people feel better after these treatments, the working explanation is attention, relaxation, ritual, and meaning: all documented influences on how people feel.

Frequency therapy for disease. Radio waves at the powers these devices produce do not carry enough energy to destroy microbes. The disease claims have never held up in testing, and several sellers have been convicted of health fraud.

The main harm from frequency-cure claims is delay: postponing effective treatment for a serious disease.

What the Evidence Supports

The body's electrical rhythms entrain to light, breath, movement, and load. Each of those levers is something you can act on: get light in the morning, breathe slowly, load your tissues, and sleep in the dark. An entrainable rhythm is real and useful; a device claimed to broadcast a curative frequency is a different claim, and testing does not support it.

• Qi, the life-force vital substance, the classical concept bioelectric signaling is compared with, and where the two part ways.

Common Questions

Are we electrical beings?

Yes, in the plain cell-biology sense. Cell voltage, nerve and muscle signaling, and the wound field are all established. What no one has shown is that those voltages steer the body's whole-organ architecture in a grown adult the way they pattern an embryo.

Do meridians exist?

Not as discrete anatomical conduits, that has been looked for and not found. The classical map does partly track the body's fascial planes (see above). That correspondence keeps it a useful clinical and descriptive system without making it anatomy.

Is there anything to red light, PEMF and other electrical devices?

Some do work, for specific conditions at specific doses. Whether a given device helps depends on the condition, and each device is graded on its own page.
