Photobiomodulation and Its Therapeutic Potential in Sleep Disturbances
Abstract
Photobiomodulation (PBM) is a non-invasive therapeutic technique employing specific wavelengths of red and near-infrared light to induce photochemical reactions in biological tissues without generating significant heat. PBM operates at low power densities, primarily acting through mitochondrial chromophores like cytochrome c oxidase to enhance cellular metabolism, energy production, and repair mechanisms. Based upon this foundational understanding, a critical evaluation was conducted to assess its impact on sleep-wake regulation. Current scientific evidence from both preclinical and clinical research suggests that PBM has the potential to influence sleep architecture, duration, and quality through complex interactions with cellular metabolic pathways and neurophysiological mechanisms governing the sleep-wake cycle…
