Bioelectricity and Healing: How Cells Use Electrical Signals to Repair and Organize
Healing is not only chemical. When tissue is injured, the body creates measurable electrical currents and fields that help guide cells involved in repair. Explore how bioelectricity influences wound healing, cell migration, regeneration, and the remarkable organization of living tissue.
When we talk about healing, we usually think in biochemical terms.
Inflammation. Collagen. Blood flow. Growth factors. Immune cells. Hormones. Genes.
All of those matter.
But healing also has an electrical dimension.
When tissue is injured, the electrical balance across that tissue changes. The normal movement of charged particles is disrupted, and the wound itself begins generating measurable electrical currents and fields.
That means an injury does more than create a chemical signal.
It also creates an electrical one.
And cells can respond to it.
WHAT HAPPENS ELECTRICALLY WHEN TISSUE IS INJURED?
Healthy epithelial tissues such as skin maintain electrical differences across their layers because ions are actively transported through channels and pumps.
When that barrier is broken, the voltage difference is disrupted. Ions leak across the damaged area, creating what researchers call an injury current and an endogenous electric field around the wound.
These fields are not theoretical. They have been measured in living tissues.
A classic review of endogenous electric fields in wound healing describes wound-generated fields in vertebrate tissues and notes that many epithelial cells, including human keratinocytes, can detect fields of physiological strength and migrate directionally in response. [Nuccitelli, 2003]
In other words, the wound creates an electrical signal—and nearby cells can read it.
CELLS CAN FOLLOW ELECTRICAL CUES
Cell migration is one of the most important parts of repair.
After injury, cells must move into the damaged area, close gaps, rebuild tissue, restore barriers, and coordinate with neighboring cells.
Researchers use the terms electrotaxis or galvanotaxis to describe directional cell movement in response to an electric field.
A 2018 review on electrically stimulated cell migration explains that physiological electric fields can activate signaling pathways involved in directional migration and can provide a dominant cue that helps guide cells toward a wound. [Zhao et al., 2018]
A 2022 review focused on wound healing describes how epithelial cells detect minute endogenous fields and can migrate collectively toward the wound center as a coordinated sheet. [Tai et al., 2022]
That is a striking idea.
Electrical information is not simply powering the cell.
It can help tell the cell where to go.
HEALING REQUIRES ORGANIZATION, NOT JUST REPAIR
A wound does not heal merely because cells multiply.
They must know how to organize.
Skin cells need to restore a barrier.
Blood vessels need to reconnect.
Nerves may need to regrow.
Connective tissue must be rebuilt.
Immune activity must eventually settle.
Cells need to stop migrating when the job is complete.
Healing is coordinated behavior.
And bioelectric signals appear to be one part of that coordination.
A systematic review examining bioelectricity in wound healing and regeneration concluded that naturally occurring voltage gradients are involved in growth, repair, and regenerative processes across animals, humans, and plants. The authors also emphasized that major questions remain about exactly how those signals encode and transmit information. [Mathews et al., 2017]
That combination is important.
The phenomenon is real.
Our understanding of it is still incomplete.
WHEN ELECTRICAL SIGNALS ARE ALTERED, HEALING CAN CHANGE
One of the strongest reasons researchers take endogenous electric fields seriously is that changing them can affect healing.
Experimental work reviewed in the wound-healing literature shows that reducing or disrupting endogenous electric fields can slow or impair aspects of tissue repair, while enhancing or externally applying appropriately directed fields can sometimes promote wound closure and regeneration.
[Nuccitelli, 2003; Messerli & Graham, 2011]
A review of the electrical response to injury describes wound-generated fields as a long-lasting, regulated biological response and notes that enhancing or inhibiting this electrical activity can increase or decrease healing, respectively. [Zhao et al., 2014]
This does not mean electricity is the only thing controlling repair.
Far from it.
Wound healing is chemical, mechanical, immune, vascular, genetic, and electrical.
The interesting part is that the electrical piece is not optional background noise.
It is part of the conversation.
WHAT ARE CELLS ACTUALLY SENSING?
This is still an active area of research.
Cells do not have tiny compass needles pointing toward a wound.
Instead, weak electric fields appear to influence ion channels, membrane proteins, receptors, intracellular signaling pathways, the cytoskeleton, and the machinery that controls cell polarity and movement.
Researchers have identified several pathways that may participate in electrical sensing, including PI3K/PTEN signaling, calcium-related mechanisms, membrane transporters, and cytoskeletal regulation.
But there is no single universal “electric-field receptor” that explains everything.
That is another reminder that biology is rarely simple.
A cell is constantly integrating many signals at once.
Chemical gradients.
Mechanical pressure.
Neighboring cells.
Nutrients.
Immune messages.
Electrical state.
Healing emerges from all of these layers interacting.
THE BODY CREATES ITS OWN ELECTRICAL ENVIRONMENT
This is where the subject becomes especially interesting to me.
We often talk about electricity as though it is something external that we apply to the body.
A pacemaker.
A defibrillator.
Electrical stimulation.
A medical device.
But the body already produces its own electrical environment.
Every intact tissue contains ion gradients.
Every cell has a membrane voltage.
Injuries create local electrical disturbances.
Groups of cells can respond collectively to those changes.
The body is not waiting for electricity to arrive from outside.
It is already using electrical information from within.
That does not make the process mysterious.
But it does make the body far more dynamic than a purely structural picture suggests.
REPAIR, REGENERATION, AND THE QUESTION OF PATTERN
Repair and regeneration are not exactly the same thing.
Repair may close a wound and restore function while leaving scar tissue.
Regeneration goes further. It recreates missing structures in an organized way.
Some animals can regenerate limbs, spinal cord tissue, tails, or other complex structures far more successfully than humans can.
Researchers studying bioelectricity are interested in whether electrical patterns help cells maintain information about anatomy—what shape should exist, where boundaries belong, and what tissue should form.
A 2017 review of bioelectricity and regeneration describes endogenous voltage patterns as information-bearing signals associated with growth, development, wound healing, and regeneration. [Mathews et al., 2017]
Research on injury-generated fields in highly regenerative nervous systems has also found that tissue damage creates strong ionic currents and electric fields that can influence migration, proliferation, and differentiation—behaviors essential to regeneration. [Cao et al., 2016]
This is not the same as saying electricity contains a complete blueprint of the body.
But researchers are asking whether bioelectric patterns participate in maintaining and restoring biological form.
That is a remarkable question.
CAN WE USE ELECTRICAL SIGNALS THERAPEUTICALLY?
Medicine has been experimenting with electrical stimulation for wound care for decades.
Research reviews have examined external electrical stimulation for chronic and difficult-to-heal wounds, including effects on cell migration, blood flow, tissue formation, and wound closure.
A 2022 review describes electrical stimulation as an emerging therapy inspired directly by the wound’s endogenous electric field, while also emphasizing that there are still major questions about optimal stimulation patterns, mechanisms, and translation into routine care. [Ashrafi et al., 2022]
More recent research continues to explore wearable devices, electroactive dressings, conductive materials, and small electrical stimulation systems intended to support tissue repair.
So this is not a fringe question.
Researchers are actively trying to understand how to work with the body’s electrical repair systems.
WHERE DOES THIS LEAVE ENERGY HEALING?
It would be tempting to make a leap here.
The body uses electrical signals during healing.
Reiki practitioners talk about energy.
Therefore Reiki must be manipulating bioelectric wound fields.
That conclusion would go beyond the evidence.
We do not know that Reiki, intuitive energy healing, chakras, meridians, or subtle-energy practices operate through these specific mechanisms.
But the science of bioelectricity does give us a more expansive picture of the body.
Healing is not only chemical.
Cells respond to voltage.
Tissues generate fields.
Electrical gradients can carry directional information.
Electrical state can influence repair.
That does not prove every energetic model.
But it does make one thing clear:
Living systems are energetic systems in a very literal biological sense.
And once we understand that, the conversation becomes much more interesting.
SCIENCE MAY MEASURE ONE LAYER OF A LARGER EXPERIENCE
Spiritual traditions have spoken for centuries about flow, blockage, balance, life force, and the restoration of harmony.
Modern biology speaks about ion gradients, membrane voltage, electrical fields, cell polarity, signaling networks, and collective tissue behavior.
Those are not interchangeable languages.
But I do not think we need to force them apart either.
Science can tell us that cells follow electrical cues toward a wound.
It can measure injury currents.
It can observe voltage gradients.
It can manipulate them experimentally.
Spiritual practice may be asking a different question:
What is the experience of wholeness, balance, flow, and connection within a living person?
Perhaps those are entirely different layers.
Perhaps someday we will understand more overlap between them.
For now, both perspectives remind us that healing is not a single event.
It is coordination.
It is communication.
It is organization.
And sometimes, part of that communication is electrical.
WHAT WE KNOW — AND WHAT WE ARE STILL LEARNING
We know that wounds generate endogenous electrical currents and fields.
We know that many cells involved in repair can respond directionally to those fields.
We know that electrical cues can influence migration, proliferation, polarity, and other behaviors important to healing.
We know that disrupting those signals can alter repair.
We know that researchers are investigating ways to use electrical stimulation and electroactive materials therapeutically.
What we do not yet fully understand is how all of this electrical information is integrated with biochemical, mechanical, genetic, immune, and perhaps other forms of signaling across the whole organism.
That is where the mystery remains.
And I think mystery is where curiosity belongs.

Your Body Is Electrical: The Science We Already Accept About Human Energy
Your heart, brain, nerves, muscles—and even ordinary cells—depend on electrical activity. Explore the science of bioelectricity, how cells use voltage as information, and why the body's electrical nature opens fascinating questions about healing and human energy.
When people hear the phrase “human energy,” the conversation can become surprisingly divided.
Some people immediately think of Reiki, chakras, qi, prana, intuition, or the aura.
Others think of those ideas as spiritual language rather than science.
But there is one part of this conversation that is not controversial at all:
The human body is electrical.
Not metaphorically. Not poetically. Literally.
Every cell in your body depends on differences in electrical charge. Your heart beats because specialized cells generate and conduct electrical signals. Your brain and nerves communicate through electrochemical impulses. Muscles contract because electrical changes across cell membranes trigger molecular events inside the cell.
And increasingly, researchers are looking beyond nerves and muscles to ask a broader question:
What role does bioelectricity play in the way cells grow, organize, communicate, repair, and maintain the structure of the body?
That question takes us into a fascinating part of modern biology—one that feels surprisingly close to conversations energy healers have been having for a very long time.
WHAT DOES “BIOELECTRICITY” ACTUALLY MEAN?
Bioelectricity refers to electrical phenomena generated by living cells.
At the most basic level, cells maintain different concentrations of charged particles—ions such as sodium, potassium, calcium, and chloride—inside and outside their membranes.
That separation of charge creates a voltage across the cell membrane, called the membrane potential.
Ion channels and pumps continually regulate these electrical differences.
Neurons are famous for using rapid changes in membrane voltage to transmit signals, but they are not the only cells with electrical properties.
A 2025 review by GuangJun Zhang and Michael Levin describes bioelectricity as an ancient and fundamental property of living cells, not something limited to nerves and muscles. The authors review evidence that bioelectric signaling participates in cell migration, proliferation, differentiation, development, regeneration, and disease. [Zhang & Levin, 2025]
That matters because our familiar picture of the body's electrical system is usually much narrower.
Most of us learned that the brain is electrical.
We learned that the heart is electrical.
We may never have been taught that electrical signaling also helps coordinate what ordinary, non-neural cells do.
THE ELECTRICITY WE ALREADY USE IN MEDICINE
Modern medicine already depends on the electrical nature of the body.
An electrocardiogram, or ECG/EKG, records electrical activity associated with the heartbeat.
An electroencephalogram, or EEG, records electrical activity generated by networks of neurons in the brain.
Pacemakers work by delivering carefully timed electrical impulses to help regulate heart rhythm.
Defibrillators use electrical energy in an attempt to restore an effective rhythm during certain life-threatening cardiac arrhythmias.
We accept these technologies because the electrical activity involved can be measured, mapped, and manipulated.
But there is something important hidden in plain sight here:
Biology and electricity are not separate topics.
Electricity is part of biology.
EVERY CELL HAS A VOLTAGE
One of the most interesting developments in bioelectric research is the recognition that membrane voltage is not simply a background condition that keeps cells alive.
It can also function as information.
In a widely cited review, Michael Levin describes how patterns of membrane voltage can influence cell proliferation, differentiation, migration, shape, and programmed cell death. Cells also communicate electrically with neighboring cells through structures such as gap junctions, creating networks of bioelectrical information. [Levin, 2014]
This does not mean cells are tiny batteries in the ordinary household sense.
But the analogy can be helpful.
Like a battery, a cell uses separation of charge to create an electrical potential. Unlike a simple battery, however, a living cell constantly changes that electrical state in response to its environment and to signals from other cells.
Researchers are increasingly interested in the possibility that these voltage patterns help cells answer questions such as:
Where am I?
What kind of cell should I become?
Should I divide?
Should I migrate?
What structure belongs here?
What should happen after injury?
Those are remarkable questions for an electrical signal to help answer.
BIOELECTRICITY AND HEALING
Wound healing is one of the clearest places where endogenous electrical activity becomes visible.
When tissue is injured, normal electrical gradients across the tissue are disrupted. This creates injury-associated currents and electric fields.
Research has shown that these endogenous electric fields can influence the direction cells migrate—a process sometimes called electrotaxis or galvanotaxis.
A systematic review of bioelectricity in wound healing and regeneration concluded that naturally occurring voltage gradients are involved in growth, repair, and regenerative processes across multiple forms of life, including humans. [Mathews et al., 2017]
Earlier work has also shown that physiological-strength electric fields can affect cell migration, orientation, and nerve growth. [Levin, 2014]
This is not speculative energy medicine.
This is biology.
And it opens an interesting door.
If the body uses endogenous electrical information during healing and organization, how much more is there to understand about the relationship between electrical state and health?
BIOELECTRICITY IS NOT THE SAME THING AS REIKI
This distinction is worth making clearly.
The scientific study of bioelectricity does not prove that Reiki energy is identical to membrane voltage, injury currents, electromagnetic fields, or any other known biological phenomenon.
Those are different claims.
But bioelectricity does challenge the idea that talking about “energy” in relation to the body is automatically unscientific.
The body is not simply matter sitting still.
It is a dynamic system of chemical reactions, electrical potentials, ion flows, mechanical forces, electromagnetic activity, and information exchange.
Science can measure some of those processes extremely well.
Others are still being investigated.
And spiritual traditions may be using a different language entirely.
The interesting question is not whether one vocabulary has to defeat the other.
The interesting question is where they might overlap—and where they might be describing genuinely different things.
THE BODY AS AN INFORMATION SYSTEM
This is the part of bioelectricity I find especially compelling.
We often think of electricity as power.
Turn on a light. Run a motor. Charge a phone.
But in living systems, electrical states can also carry information.
A review on bioelectrical cell biology describes ion- and redox-based electrical processes as part of the communication systems that help organize growth and behavior in both prokaryotic and eukaryotic cells. [Cervera et al., 2020]
Another recent review argues that bioelectricity can operate at multiple levels—from the individual cell to tissues and whole organisms—and may help groups of cells coordinate behavior collectively. [Zhang & Levin, 2025]
That starts to sound less like electricity as a simple fuel and more like electricity as part of a language.
A language of voltage.
A language of pattern.
A language through which living cells participate in the organization of the whole.
That does not make the body mystical.
But it does make the body extraordinary.
WHAT SCIENCE KNOWS — AND WHAT IT IS STILL LEARNING
Science already knows that:
Every living cell maintains an electrical potential across its membrane.
The heart, nervous system, and muscles depend on electrical signaling.
Electrical states influence many cellular behaviors.
Endogenous electric fields participate in wound healing and cell migration.
Bioelectric patterns are being studied in development, regeneration, cancer, and regenerative medicine. [Levin et al., 2019]
What science does not yet know is equally interesting.
How much information is carried by large-scale bioelectric patterns?
How do electrical, biochemical, mechanical, and genetic signaling systems interact as a whole?
Can bioelectric states someday be deliberately altered to promote complex tissue repair or regeneration?
And from the perspective of energy healing:
Are any of the sensations, shifts, or patterns people experience during energy work related to known bioelectrical processes?
Or is energy healing engaging with something science has not yet learned how to characterize?
We do not know.
And again, not knowing is not a problem.
It is an invitation to keep looking.
SCIENCE AND SPIRITUALITY DO NOT NEED THE SAME VOCABULARY
Traditional healing systems spoke about qi, prana, meridians, chakras, life force, and energetic balance long before modern electrophysiology existed.
Modern biology speaks about ion gradients, membrane potentials, gap junctions, endogenous electric fields, electromagnetic signals, and bioelectric networks.
Those terms are not interchangeable.
But I think there is value in placing them beside one another without forcing either side into a conclusion it has not earned.
Ancient practitioners did not have voltage-sensitive dyes, electrodes, microscopes, or molecular genetics.
Modern laboratories may be able to measure processes that earlier cultures could only experience indirectly—or the two traditions may be describing different layers of human experience.
Either possibility is interesting.
The body is electrical.
That much is established.
What that fact may eventually teach us about healing, consciousness, organization, and the deeper nature of living systems is still unfolding.
And I think that is a wonderful place to remain curious.
