How LED Light Triggers Healing

Light stimulates healing reactions in the body—reactions that continue even after the light is removed. Tiina Karu’s research, exploring the specific ways monochromatic or single colors of LED light trigger healing, proved LED light improves metabolism. Metabolism is an all-encompassing term used to describe the chemical and biological processes that sustain life. A high level of metabolism means: 

Metabolism is a process crucial to health. The fact that LED therapy improves metabolism helps account for the widespread healing effects. An amazing circle of events starts by simply showering cells with LED light. At least three healing processes are triggered within cells to improve metabolism: 


Enzymes are catalysts needed for every chemical reaction. We function at a high level when enzymes are plentiful. Research is proving LED light restores or promotes enzymes to speed the healing process. 

Dr. Sherry Rogers sums up the research by explaining the reaction within our cells: 

… the LED reversed the damage to the enzyme cytochrome oxidase. This enzyme is actually stimulated by light in the far red visible to near-infrared spectra as it strongly absorbs this stimulating energy. This energy transfusion in turn increases electron transfer in the mitochondria, leading to increased energy synthesis for healing. … Cytochrome oxidase is just one of several enzymes that can be turned on by light.16

Mitochondria are an area within cells that use raw materials and convert them to energy. Mitochondria are the powerhouse for each cell.


The boost in enzymes creates more ATP or Adenosine triphosphate. More ATP means more energy. More energy means easier and faster healing … and being better able to handle life’s challenges and enjoy the process. 

Dr. Whelan sums up the NASA sponsored research with regards to energy: 

So far, what we’ve seen in patients and what we’ve seen in laboratory cell cultures, all point to one conclusion, … The near-infrared light emitted by these LEDs seems to be perfect for increasing energy inside cells. … the LEDs boost energy to the cells and accelerate healing.5

Dr. Tiina Karu emphasizes the importance of ATP saying “… ATP is not only an energy currency inside cells, but it is also a critical signaling molecule that allows cells and tissues throughout the body to communicate with one another.”22


How do cells know what to do? It starts with DNA. Each cell contains DNA—a spiral shaped storehouse for light and sound frequencies—and the blueprint for a cell to replenish or replace itself. DNA is our blueprint for health. 

Dr. Whelan explains how light applied in both the red and near infrared ranges worked: “Furthermore, DNA syntheses in fibroblasts and muscle cells has been quintupled using NASA LED light alone …”23

This means the forming power of our cells has been increased by five times in muscle cells with the application of three colors of LED light in the red to NIR range.Back to Top >

Summing Up

LED light stimulates a powerful team to harness our cells for health and energy—enzymes, ATP and DNA. It is also important to note that Dr. Karu emphasizes that LED light acts as a trigger to start the healing process. In other words, healing effects continue after the light source has been removed. 

LEDs have given us a convenient and easy way to use light therapy for health. LED technology has made it easy to add special healthy frequencies to light therapy. The Nogier frequencies, in particular, are known to boost the healing power of the LED light therapy. 

Light therapy is a trigger to help maintain the flow of our natural electrical and chemical systems. LED technology has brought us a wonderful tool for health.
