Red Light Therapy
Red light therapy is a treatment that uses specific wavelengths of red or near-infrared light to promote healing, reduce inflammation, and provide various other health benefits. This type of therapy is sometimes called low-level laser therapy (LLLT) or photobiomodulation (PBM) Red light therapy (RLT) has a significant impact on mitochondria, the energy-producing organelles within cells. The mitochondria are often referred to as the "powerhouses" of the cell because they generate adenosine triphosphate (ATP), the primary energy currency of the cell. The interaction between red light therapy and mitochondria is central to understanding many of the therapy's benefits.
How Red Light Therapy Affects Mitochondria
Photon Absorption:
When red or near-infrared light penetrates the skin, it is absorbed by chromophores within the mitochondria.
Increased ATP Production:
The absorption of light by cytochrome c oxidase enhances the enzyme’s activity. This, in turn, increases the efficiency of the electron transport chain, leading to a higher production of ATP. More ATP means more energy for cellular functions, which can accelerate healing and regeneration processes.
Reduction of Oxidative Stress:
Red light therapy can also reduce oxidative stress within cells. By improving the efficiency of the electron transport chain, it reduces the leakage of electrons that can form harmful reactive oxygen species (ROS). Lower ROS levels mean less oxidative damage to cellular components.
Enhanced Cellular Signaling:
The increased ATP production and reduced oxidative stress improve cellular signaling. This can result in various beneficial outcomes, including reduced inflammation, enhanced tissue repair, and improved cell survival.
Increase NO:
The release of NO, a potent vasodilator, increase circulation, decrease inflammation and enhances the transport of oxygen and immune cells through tissue
