Greenfield frames the body as an electrochemical battery whose cells and mitochondria rely on gradients, electron transport, and mineral movement. Once basic movement and natural food are in place, he layers five environmental inputs: grounding, broad-spectrum or therapeutic light, heat, cold, and mineral-rich hydration. The sequence starts with accessible options such as twenty minutes barefoot outdoors, sensible sunlight, clean water, and mineral-rich food or salt. Indoor grounding mats, red-light panels, saunas, and other devices are substitutes or amplifiers rather than prerequisites. The model's value is its hierarchy: use several modest inputs consistently instead of expecting one expensive biohack to compensate for a sedentary, highly processed lifestyle. Exposure should remain sensible, especially around sunlight, electricity, heat, and cold.
Origin
Greenfield presents this stack when asked for high-impact habits beyond exercise and natural eating. He uses the battery metaphor to connect grounding, light, temperature exposure, water, and minerals into one mechanism.
Core principles
- 01Build advanced habits only after movement and natural food
- 02Use free environmental inputs before expensive devices
- 03Combine complementary inputs rather than chasing one hack
- 04Avoid burning and other preventable exposure risks
- 05Treat technology as a substitute when nature is inaccessible
How to run it
- 1
Secure the foundation
Confirm that regular movement and mostly natural food are already present. Treat the stack as an addition to those basics, not a replacement.
Pro tip Fix the cheapest foundational gap before buying equipment.
Watch out Biohacks cannot reliably compensate for inactivity or a highly processed diet.
- 2
Ground daily
Spend regular time barefoot or with bare skin on the earth, ideally around twenty minutes or more. Natural mineral-rich water is presented as an especially strong option.
Pro tip Use a properly installed grounding mat when work keeps you indoors.
Watch out Use electrical products only as designed and avoid improvised unsafe setups.
- 3
Match light to the job
Use sunlight for broad-spectrum and circadian exposure, while red or infrared light can provide targeted indoor exposure. Keep total sunlight below the point of burning.
Pro tip Use brighter blue-green light earlier and warmer or redder light toward bedtime.
Watch out Red light does not replace every circadian property of sunlight.
- 4
Add temperature variation
Include an appropriate form of heat and cold on a regular basis. Choose a dose that creates manageable adaptation rather than excessive stress.
Pro tip Start with the form you can repeat consistently.
Watch out Screen cardiovascular and other health risks with a qualified professional.
- 5
Hydrate with mineral variety
Drink clean filtered water and obtain minerals from food, electrolytes, and varied mineral-rich salts. Avoid relying only on isolated sodium chloride.
Pro tip Use mineral-rich produce and a balanced electrolyte source as the base.
Watch out Individual sodium, kidney, and blood-pressure needs vary.
- 6
Audit consistency and effect
Review which layers are actually being used and whether energy, mood, sleep, or recovery changes over time. Remove expensive elements that do not add value.
Pro tip Introduce one optional device at a time.
Watch out Subjective improvement alone does not validate every biological claim behind a device.
In the wild
A remote worker begins with walking and natural food, stands on a properly connected grounding mat, uses daylight or morning circadian light, spends a bounded period near a red-light panel, takes a sauna or cold plunge when appropriate, and drinks filtered water with balanced minerals.
→ The worker recreates several environmental inputs consistently without needing to work outdoors all day.
A person walks barefoot on grass or enters the ocean, gets non-burning sunlight, uses ordinary hot and cold exposure conservatively, drinks filtered water, and eats mineral-rich produce with varied salt.
→ They apply the hierarchy without buying specialised biohacking equipment.
Common mistakes
Buying devices before fixing basics
The stack assumes movement and natural eating are already reasonably established. Technology is an amplifier, not the foundation.
Treating all light as interchangeable
Red light and sunlight overlap in some claimed effects, but blue-green daylight has a distinct circadian role.
Ignoring exposure safety
Sunburn, extreme temperatures, and improvised electrical grounding can create avoidable risk.
Is it for you?
Best for
It is best for already-active people who eat reasonably well and want a simple hierarchy for optional wellness practices.
Not ideal for
It is not ideal as a substitute for medical care, foundational diet and movement, or individual safety screening.
