What is Red Light Therapy?

KOZE S Series

Red light therapy (RLT), also known as photobiomodulation therapy (PBM), involves exposing tissues to low levels of red or near-infrared light. The primary source of this light is LED bulbs, which emit light at specific, therapeutic wavelengths, typically between 600 and 900 nanometers. Unlike ultraviolet light, which can cause damage to the skin, red light is safe and penetrates the skin without causing any harm.

Historical Background

The discovery of red light's therapeutic effects dates back to the 1960s, when researchers found that certain frequencies of light could accelerate growth in plants. Further research led to the application of similar principles in treating human conditions. The transition to more veterinary medicine applications followed, driven by the positive outcomes observed in humans, particularly for healing wounds and reducing inflammation.

Mechanism of Action

KOZE S Series

At the cellular level, red light therapy works by delivering energy directly to the cells, which absorb this light and convert it to cellular energy (ATP). This process stimulates various cellular activities that lead to reduced inflammation, pain relief, and accelerated tissue repair. Specifically, the light triggers the release of nitric oxide, a critical compound that enhances blood circulation, reduces oxidative stress, and improves cellular metabolism.

Key Points:

  • Wavelengths Used: Typically between 600 and 900 nm, targeting deep tissue penetration without damaging the skin.

  • Safety: Unlike UV light, red light does not cause DNA damage or cancer risks.

  • Applications: Initially used in plant growth experiments, it is now widely used in medical and veterinary fields.

How Does Red Light Therapy Work for Dogs?

Understanding the mechanics of red light therapy in dogs involves a deeper look into the interaction between laser light and biological tissues. The process is fundamentally the same as in humans, but with considerations specific to canine anatomy and physiology.

Scientific Basis

When red light enters the body, it penetrates the skin and underlying tissues to a depth of about 8 to 10 millimeters, which is ideal for targeting muscles, tendons, and even bone surfaces. At this depth, the light photons are absorbed by mitochondria, the powerhouses within cells, which then use this energy to enhance cellular function.

This mitochondrial stimulation is crucial because it leads to increased production of adenosine triphosphate (ATP), the energy currency of the cell. With more ATP available, cells can perform their functions more efficiently, particularly in healing and promoting cellular regeneration itself.

Effects on Canine Health
