Red light and Infrared
In light therapy, both red light and infrared light are utilized, each with its specific wavelength and therapeutic benefits.
- Red Light Therapy: This therapy employs wavelengths typically ranging from 620 to 750 nanometers. Red light is known to penetrate the skin’s surface, stimulating the production of collagen, promoting wound healing, reducing inflammation, and aiding in the repair of damaged tissues. It’s commonly used for skincare, wound healing, and pain relief.
- Infrared Light Therapy: Infrared light therapy utilizes wavelengths longer than those of red light, typically falling between 750 nanometers to 1 millimeter. Infrared light penetrates deeper into the body, reaching muscles, joints, and even bones. It’s known for its ability to increase circulation, relieve muscle and joint pain, reduce inflammation, and promote relaxation. Infrared therapy is often used for muscle recovery, pain management, and improving overall well-being.
While both red light and infrared light therapies offer therapeutic benefits, they differ in the depth of penetration and the specific biological responses they trigger.
