Mimic and Concentrate begins with an ancestral environmental input and asks how to preserve its biological function in modern life. Sunlight can be used directly or approximated with red-light devices; natural temperature variation can be recreated with sauna or cold exposure; contact with the ground can be supplemented with grounding tools; and diverse plants can be supplemented with concentrated powders or capsules. The mechanism is substitution, not novelty for its own sake: identify what the natural exposure appears to do, use the original source whenever practical, and deploy technology when modern work, climate, or geography blocks access. Greenfield combines both modes, such as using an infrared sauna in the morning and walking in sunlight later, rather than insisting on an all-natural or all-technological lifestyle.
Origin
Ben Greenfield describes living with one foot in ancestral wisdom and the other in modern science, using technology to reproduce natural inputs.
Core principles
- 01Start with a biological input humans experienced naturally
- 02Use direct natural exposure when it is practical
- 03Use technology to simulate or concentrate the same input when access is limited
- 04Combine ancestral practices and modern tools rather than treating them as rivals
How to run it
- 1
Name the missing input
Audit your routine for natural stimuli such as sunlight, ground contact, temperature variation, fresh air, water-rich produce, or diverse plants. Choose one meaningful gap rather than buying a collection of devices.
Pro tip Start with the exposure your environment suppresses most consistently.
Watch out Do not assume every ancestral hardship was beneficial.
- 2
Use nature first
Find the simplest direct version of the input that fits your life, such as a daylight walk or outdoor meal. Keep it easy enough to repeat.
Pro tip Attach the exposure to an existing activity such as a call or commute.
Watch out Do not let an ideal outdoor routine become an excuse to do nothing.

Choose a faithful substitute
When natural access is blocked, select a tool that recreates the relevant stimulus. Match light to light, temperature to temperature, and plant diversity to food or concentrated plant sources.
Pro tip Define the stimulus before comparing products.
Watch out A fashionable device is not useful merely because it is called a biohack.
- 4
Combine both modes
Use technology for consistency and nature when available. Build a routine that can survive dark winters, travel, or office-heavy days without abandoning direct exposure.
Pro tip Create a natural default and an indoor fallback.
Watch out Concentrated exposure may require more caution than its natural counterpart.

Review the fit
Check whether the intervention is repeatable and addresses the original gap. Remove expensive or complicated tools that do not improve adherence.
Pro tip Judge the system by consistency, not gadget count.
Watch out Do not confuse a plausible mechanism with proven treatment of disease.
In the wild
Greenfield contrasts sunlight with red-light lamps, infrared saunas, and head-worn light devices. Someone working indoors during a dark Seattle winter can use targeted light technology when daylight exposure is unavailable, then still take natural light when conditions permit.
→ The biological input remains part of the routine despite climate and work constraints.
Modern temperature-controlled life removes the hot and cold fluctuations once experienced outdoors. Greenfield uses infrared sauna and cold exposure to deliberately restore temperature stress rather than depending on occupation or weather.
→ A missing environmental stressor becomes a scheduled, controllable practice.
Common mistakes
Buying before diagnosing
Purchasing a device before identifying the missing natural input turns the framework into gadget collection.
Treating nature and technology as rivals
The method works by combining direct exposure with practical substitutes, not by choosing one camp.
Overstating health claims
A proposed mechanism or personal routine should not be presented as a proven cure for disease.
Is it for you?
Best for
People whose work or location limits regular access to sunlight, natural ground, temperature variation, or whole foods.
Not ideal for
Medical conditions where concentrated heat, cold, light, or electromagnetic exposure requires professional guidance.
From the transcript
“some of the more beneficial tools that we can find in modern science for enhancing the human body, are simply mimicking and concentrating what primal…”
“do a little bit of both, right? Like I was in the infrared sauna this morning and now I'm walking in the sunlight.”
