LIGHT THERAPY
What is Photobiomodulation?
Photobiomodulation is otherwise known as light therapy.
Light therapy involves the use of light-emitting diodes (LEDs) to deliver a specific wavelength of light that can be absorbed by cells in the body. The LED type determines the wavelength of light and can be tuned to a particular tissue or organ.

All biological activity in our body requires ATP just like plants require chlorophyl.

Increases Cellular Energy
History of Light Therapy
Light therapy has been used for centuries for healing purposes. Hippocrates discovered that applying sunlight to the skin could relieve ailments such as rickets, scurvy and arthritis. However, until recently, scientists began understanding how this worked on a cellular level.
Understanding Wavelengths:
810 vs 1070
The 1070nm LED’s are unique in that they penetrate further into the skull targeting the mitochondria. A study named Photobiomodulation at Different Wavelengths (Pruit, 2022) shows the difference between two wavelengths around 800 and 1070. The study states “the 1064nm sustained longer and more increases of the physiological effects as compared to the other.” The study was done with lasers first, then compared to LED’s, and suggested using LED’s as a safer and more important role in the development of PBM.
Research is also being conducted in the UK by Paul Chazot at Durham University and he explains clearly in this video why the 1070 is the wavelength they are focused on.

A Cellular Breakdown
Photobiomodulation is defined as the use of light energy to trigger photochemical changes within cellular structures (mitochondria) that are receptive to red and near-infrared (NIR) light. The mitochondria produce cellular energy by producing a molecule called adenosine triphosphate (ATP). The energy from ATP enables us to carry out all physiological activities and provides energy to the brain cells. In addition, application of light energy leads to greater blood flow to the brain – allowing delivery of nutrients and removal of waste products.
This is a new way of ‘charging’ the brain and now research is starting to show significant benefit of this therapy for brain health
Using EEG to Apply PBM
“Photobiomodulation is more than an alternative kind of medical treatment. It is a whole new method to control cellular processes and modulate living organisms by precise alterations in the chemistry of biomolecules."
Harvard Pioneer Researcher, Michael Hamblin, PhD
Key Mechanism in Action
The expression of several genes and proteins that play a role in disease mechanisms seen in cognitive decline surprisingly changes during long-term use of Photobiomodulation (PBM) (Bathini, Raghushaker and Mahato, 2020).
By now, we can understand that mitochondrial dysfunction appears to be a central mediator of neurodegenerative disease pathogenesis and disease progression.
