Curious about red-light therapy but not sure where to start? In this episode I unpack the science of photobiomodulation aka red light therapy, break down the evidence behind the key wavelengths (630 nm, 660 nm, 830 nm & 850 nm), and demo my own red light device, the MitoPRO 300+. I take a practical, evidence-based look at fitting a compact LED panel into a busy lifestyle.
