Red light therapy isn’t magic, but understanding how it works can change how you use it. In this science-focused episode, Bart explains the core mechanisms behind red light therapy and why understanding the “how and why” is crucial for achieving real-world results.

This video explores the three primary mechanisms of photobiomodulation supported by current research, including mitochondrial activation, growth factor stimulation, and modulation of cell membrane ion channels. You’ll learn why researchers don’t fully agree on everything yet, why different tissues respond differently to light, and how mechanisms help explain why red light works well for some conditions — and less so for others.

This episode is part of a free, science-driven red light therapy course designed to help you understand the foundations, cut through hype, and apply light therapy more intelligently over time.
