Electromagnetic radiation, particularly within the visible and near-infrared spectrums, utilized therapeutically to influence cellular processes, including mitochondrial function and cellular energy production. In the context of wellness, specific wavelengths are employed to modulate cellular signaling pathways relevant to tissue repair and hormone receptor expression. This energy acts as an external modulator of internal biochemistry.
Origin
The term originates from physics, describing energy transmitted in discrete units called photons. Its application in biology relates to photobiomodulation, where light energy is absorbed by cytochrome c oxidase within the mitochondria. This absorption has cascading effects on cellular respiration and ATP synthesis.
Mechanism
Photonic energy is absorbed by chromophores within the cell, leading to increased production of reactive oxygen species (ROS) in a controlled manner, which then triggers transcription factors that enhance cellular repair and reduce inflammation. Exposure timing and wavelength specificity are critical determinants of the physiological outcome, influencing cellular metabolic efficiency which underpins hormonal balance.
