Photobiomodulation (PBM), also known as low-level laser therapy (LLLT) or red light therapy, is a non-invasive medical technique that employs low-level light in the visible and near-infrared spectrum to stimulate cellular function and promote healing. This innovative approach harnesses the therapeutic properties of specific wavelengths of light to enhance various physiological processes within the body. The light energy is absorbed by mitochondria, the powerhouse of cells, triggering a cascade of beneficial effects such as increased production of adenosine triphosphate (ATP), improved cellular metabolism, and modulation of inflammation. PBM has shown promising results in accelerating tissue repair, reducing pain and inflammation, and promoting neuroregeneration. This versatile therapy finds applications in diverse medical fields, including wound healing, musculoskeletal disorders, dermatology, and even neurological conditions. The non-thermal, non-invasive nature of PBM makes it a safe and well-tolerated modality with minimal side effects. As research in photobiomodulation continues to expand, its potential to revolutionize therapeutic interventions and enhance overall well-being becomes increasingly evident, positioning it as a promising avenue for the future of medical treatment and rehabilitation.
