What is Cold Laser Therapy?
Cold laser therapy is a low-intensity laser therapy that stimulates healing in the body using low light levels.
The procedure is called “cold” laser therapy because the light levels are not designed to heat your body’s tissue. As a result, the light is produced at low levels compared to other forms of laser therapy, for example, those used to coagulate tissues and destroy tumors.
Aesthetic and surgical lasers heat the tissue that is being treated. On the other hand, the cold laser does not.
Cold therapy is also known by other names such as:
- Photobiomodulation
- Soft laser biostimulation
- Low-power laser therapy
- Low-level laser therapy
How does it work?
Low-level light of different wavelengths and outputs is applied to a targeted area during cold laser therapy. The body tissue absorbs the light. Red and near-infrared light cause a reaction, triggering a physiological reaction from the damaged cells that promote regeneration.
Superficial tissue is treated with lights of wavelengths 600 to 700 nanometers. Then, lights of wavelengths 780 to 950 nanometers are used for deeper penetration.
