Red Light Therapy utilizes visible red light (wavelength 600-760nm) to stimulate mitochondria within human cells, significantly boosting catalase activity. This process enhances cell metabolism, increases glycogen content, promotes protein synthesis, and facilitates adenosine triphosphate decomposition. These effects collectively strengthen cell regeneration, accelerate granulation tissue growth, and expedite wound healing. Moreover, red light therapy augments the phagocytic function of white blood cells, bolstering immune responses and providing anti-inflammatory and analgesic benefits.
In contrast, infrared light (wavelength 760nm-2.5um) elevates tissue temperature, dilates capillaries, accelerates blood flow, and enhances material metabolism. This mechanism improves tissue cell vitality and regeneration capabilities, making it particularly effective in treating chronic inflammation. By boosting blood circulation and increasing cell phagocytosis, infrared light aids in reducing swelling, dissipating inflammation, and alleviating muscle spasms in both striated and smooth muscles.
Optoelectronics studies highlight that mitochondria, often referred to as the body's energy factories, absorb visible red light most efficiently. Addressing energy deficits in these vital cellular components through moderate red light irradiation replenishes mitochondrial energy stores, offering therapeutic benefits across various bodily discomforts.
Red light therapy harnesses the catalytic potential of mitochondria to enhance cellular metabolism, foster tissue regeneration, and fortify immune responses. Its dual-action approach, involving visible red and infrared light, underscores its efficacy in promoting holistic healing and pain management.
