Cold laser therapy, also known as low-level laser therapy (LLLT), is a form of alternative medicine that uses low-power lasers or light-emitting diodes (LEDs) to treat a variety of conditions, including pain, inflammation, and wound healing. The therapy is called "cold" laser because it uses low-intensity light, which does not generate heat or cause damage to the skin or other tissue.
During a cold laser therapy session, the practitioner directs the light from the laser or LED device onto the area of the body being treated. The light energy is absorbed by the cells, which then boosts blood flow, reduces inflammation, and promotes tissue healing. It is commonly used to treat chronic pain, such as back pain or arthritis, as well as injuries to tendons, ligaments, and muscles.
