Light Therapy Glossary
Key terms to understand photobiomodulation therapy
Photobiomodulation (PBM)
The scientific term for light therapy that uses red and near-infrared wavelengths to stimulate cellular function, reduce inflammation, and promote healing.
Wavelength
Measured in nanometers (nm), wavelength determines the color of light and its penetration depth. Red light (630-660nm) and near-infrared (810-850nm) are most therapeutic.
Joules
The unit of energy delivered during treatment. Optimal therapeutic dose typically ranges from 3-15 joules per cm² depending on the condition being treated.
Power Density
Measured in mW/cm², this indicates the intensity of light delivered to tissues. Effective therapeutic ranges are typically 30-100 mW/cm².
Chromophores
Light-sensitive molecules in cells that absorb photons. Cytochrome c oxidase in mitochondria is the primary chromophore in red/NIR light therapy.
Mitochondria
The "powerhouse" of cells that produce ATP energy. These organelles are primary targets of red and near-infrared light therapy.
ATP (Adenosine Triphosphate)
The primary energy carrier in cells. Light therapy increases ATP production, providing more energy for cellular repair and regeneration.
Nitric Oxide
A signaling molecule released during light therapy that improves blood flow, oxygen delivery, and triggers various healing mechanisms.
Cytokines
Signaling proteins involved in inflammation. Light therapy helps regulate pro-inflammatory and anti-inflammatory cytokines to promote healing.
Biphasic Dose Response
The principle that light therapy follows a "sweet spot" pattern—too little energy has no effect, while too much can inhibit benefits.
The Science of Healing Light
Photizo uses LED-based light therapy to deliver specific, pre-programmed doses of red and near-infrared light, stimulating your body's natural healing processes at a cellular level.
Light is absorbed by mitochondria, the 'powerhouses' of your cells. This energizes the electron transport chain, boosting the production of ATP—the essential energy currency for all cellular functions, including repair and regeneration.
By providing cells with more energy, Photizo helps reverse cell death processes after injury. It promotes faster cellular regeneration, regulates collagen production to minimize scar tissue, and stimulates the creation of new blood vessels (angiogenesis) for better nutrient delivery.
Light therapy helps clear inflammation by increasing lymphatic activity. Research shows it can double the diameter of lymph vessels, allowing for faster drainage of waste products and proteins that cause swelling and cellular stress.
Photizo helps reduce the excitability of nerve tissue, providing direct pain relief at the treatment site. It also has a systemic effect, promoting an increase in endorphins and serotonin, which further contributes to a feeling of well-being and pain reduction.
