Red Light Therapy Mechanisms: NO, ROS, ATP, and Transcriptional Signaling
Beyond cytochrome c oxidase absorption: nitric oxide release, controlled ROS signaling, ATP shifts, and gene transcription cascades—biphasic and context-dependent, not magic mitochondria memes.

Red Light Therapy Dosing: Irradiance, Fluence, Distance, and Session Parameters
J/cm² = mW/cm² × seconds / 1000. Distance changes dose. Reciprocity fails in PBM—report wavelength, irradiance, time, area, and schedule together.

Red Light Therapy Device Quality: LEDs vs Lasers, Irradiance Claims, and FDA Clearance
Wavelength and dosimetry beat brand watts. LED≈laser when parameters match. FDA 510(k) clearance is not pan-indication proof—demand spectrometry and irradiance maps.

Red Light Therapy Biphasic Dose Response: Arndt-Schulz and Why More Is Not Better
Photobiomodulation shows biphasic dose responses: too little does nothing; too much can inhibit. Fluence, irradiance, and distance beat unlimited session bragging.

Photobiomodulation Dosing: Irradiance, Fluence, and Biphasic Response
Fluence is not irradiance. J/cm² = mW/cm² × seconds / 1000. Too little does nothing; too much can inhibit—Arndt–Schulz in practice.
