What is the Origin of Low-Level Laser Therapy?

The term arose with the clinical application of lasers in the mid-20th century, combining "low-level laser" to denote the non-thermal power output with "therapy," meaning treatment. The shift to the term "photobiomodulation" reflects a more precise scientific understanding of the light's mechanism of action on biological processes.

What is the Mechanism of Low-Level Laser Therapy?

LLLT's primary mechanism involves the absorption of photons by cytochrome c oxidase, a key enzyme in the mitochondrial electron transport chain. This absorption increases mitochondrial respiration, leading to enhanced ATP production and the modulation of reactive oxygen species. The resulting boost in cellular energy and signaling molecules promotes anti-inflammatory effects, accelerates tissue regeneration, and improves local blood flow, which can indirectly support endocrine organ health.

Low-Level Laser Therapy

Meaning

Low-Level Laser Therapy (LLLT), also known as photobiomodulation (PBM), is a non-invasive therapeutic modality that utilizes specific wavelengths of low-power light to stimulate cellular function without causing thermal damage. This therapy is employed clinically to promote tissue repair, reduce inflammation, and alleviate pain across various conditions. In the context of hormonal health and wellness, LLLT may be used to enhance localized circulation or modulate cellular energy production in tissues like the thyroid or gonads. The light energy is absorbed by chromophores within the cells, initiating a cascade of biological effects.
