What is meant by "photobiomodulation" in laser therapy?

Photobiomodulation refers to the phenomenon where light energy is absorbed by cells, leading to various biological responses that promote healing and tissue repair. This process primarily involves the absorption of specific wavelengths of light by chromophores within the cells, which triggers molecular and cellular mechanisms that can enhance healing, reduce inflammation, and alleviate pain.

The absorption of light during photobiomodulation stimulates mitochondria, leading to an increase in ATP (adenosine triphosphate) production, which is essential for cellular energy. This boost in energy can accelerate the healing process by facilitating cellular functions such as proliferation, migration, and extracellular matrix synthesis.

In laser therapy, using specific wavelengths that are effective in promoting these responses allows practitioners to harness the natural healing properties of light, making it a powerful tool in both clinical and therapeutic settings.
