Red Light Therapy for Beginners: The Science Behind Red Light Therapy

Red Light Therapy involves the use of low-energy, red or near-infrared light wavelengths to penetrate the skin and interact with cells in the body. These wavelengths typically range from approximately 630 to 850 nanometers and are in the non-ionizing radiation spectrum, which means they do not have the harmful properties associated with ultraviolet (UV) rays.
The key principle behind Red Light Therapy is photobiomodulation, which refers to the process where light energy is absorbed by cellular components, leading to various biological effects. It stimulates cellular energy production, specifically in the form of adenosine triphosphate (ATP), the cell's energy currency. This increase in energy production promotes several positive changes within the body.
Red Light Therapy can be administered through a variety of devices, including low-level laser therapy (LLLT) devices, light-emitting diode (LED) panels, and handheld units. These devices emit red and near-infrared light, which is applied directly to the skin or tissues in the targeted area. The therapy is non-thermal, meaning it doesn't produce heat, and is considered safe for most individuals.
