The Body Electric – Circadian Rhythms, Cell Voltage, and the Biology of Healing

Modern life has changed the way we live, eat, and sleep. We spend most of our time indoors under artificial light, exposed to screens late into the evening, disconnected from the natural rhythms of day and night. For many, this disruption of circadian biology underpins fatigue, brain fog, poor sleep, and chronic illness.

Alongside this,  our bodies are not just chemical, but electric systems. Cells rely on voltage, charge, and energy flow across membranes to function. When this “cellular battery” runs low,  healing becomes impossible.

This is the essence of Dr Jerry Tennant’s work in Healing is Voltage and Dr Robert Naviaux’s groundbreaking research on the Cell Danger Response (CDR). Together, they show us that health is not simply the absence of disease, but the presence of energy, rhythm, and flow.

The Body Electric: Voltage and Healing

Every cell maintains an electrical potential across its membrane — a separation of charges that allows nutrients in, wastes out, and communication with other cells.

• A healthy cell typically has a resting voltage of about -20 mV.
• When voltage drops, cells lose their ability to repair and regenerate.
• Chronic inflammation, toxins, infections, or nutrient deficiencies can all deplete this voltage.

As Tennant explains, healing requires energy –  literally electrons and charge to power the body’s repair systems¹.

The Cell Danger Response

Dr Robert Naviaux has shown that mitochondria are not only the cell’s powerhouses, but also its environmental sensors. When they detect danger from infection, toxins, trauma they shift metabolism into defence mode.

This Cell Danger Response (CDR) is designed to protect the body short-term by conserving resources, lowering communication, and prioritising survival.

But if the body remains “stuck” in this state, cells never return to normal healing and repair. Instead, chronic illness develops – with fatigue, brain fog, pain, and immune dysfunction².

Circadian Biology: Timekeepers of Health

The body has a master clock in the brain (the suprachiasmatic nucleus) and countless “peripheral clocks” in each organ and cell.

These clocks are synchronised by light exposure, food timing, and daily rhythms.

• Morning light sets the clock for wakefulness, hormone release, and metabolism.
• Night-time darkness allows melatonin release, repair, and detoxification.
• Deep sleep activates the glymphatic system, clearing toxins from the brain³.

When circadian rhythms are disrupted – through shift work, late-night screen use, irregular eating – the result is mitochondrial stress, impaired repair, and a drop in cellular voltage⁴.

Functional Implications

When we combine these perspectives, the picture is clear:

• Low voltage = cells cannot heal (Tennant)
• Stuck CDR = body trapped in defence mode (Naviaux)
• Circadian disruption = no rhythm of repair (Panda, Walker)

This triad helps explain why so many people with chronic illness fail to improve with diet and supplements alone. Without energy, safety signals, and circadian alignment, the body cannot move into repair.

Practical Steps to Support Your Body’s Electricity and Rhythms

1. Morning sunlight: Aim for 10–15 minutes of outdoor light soon after waking.
2. Dim evenings: Avoid bright/blue light 2–3 hours before bed, or use warm-spectrum bulbs.
3. Regular sleep: Keep consistent sleep and wake times.
4. Grounding: Contact with the earth can support electron flow and reduce excess charge.
5. Nourish membranes: Omega-3s (oily fish), phospholipids (eggs, flaxseeds), magnesium (nuts, swiss chard , and hydration maintain healthy cell charge.
6. Reduce toxic load: Remove environmental exposures that keep mitochondria in defence mode.
7. Eat with rhythm: Align meals with daylight hours; avoid late-night eating.

The Takeaway

Health is not just about biochemistry,  it’s about energy, rhythm, and flow.

By restoring voltage across cell membranes (Tennant), guiding cells out of the danger response (Naviaux), and aligning with circadian biology, we create the conditions for true healing.

The body is electric, and when it has the right charge and rhythm, it has the power to repair, regenerate, and thrive.

What simple changes could you add in to your daily routine to recharge your internal battery and reset your circadian clocks?
