Near-Infrared Signaling

Meaning

Near-Infrared Signaling refers to the biological effects elicited by exposure to light in the near-infrared (NIR) spectrum, typically wavelengths between 700 and 1400 nanometers. Unlike visible light, NIR light penetrates deeper into tissues and is hypothesized to exert therapeutic effects by interacting directly with cellular components, particularly within the mitochondria. This signaling is thought to enhance cellular energy production, reduce inflammation, and promote tissue repair. Clinically, this is utilized in various light therapy modalities for skin health, pain management, and systemic wellness.
