James Carroll interviewed on The PEMF Podcast about Photobiomodulation

Posted on 8 March 2026 by Ian


The interview starts at 1:30 minute mark.

The PEMF Podcast sat down with James Carroll, a Photobiomodulation (PBM) pioneer with nearly 40 years in the field, to separate real science from marketing hype. From irradiance and wavelength selection to dose-response curves and proper measurement standards, James explains why many popular consumer devices fail to deliver therapeutic levels of light despite impressive claims.

Questions James was asked: Are red light masks, blankets and handheld wands actually doing anything? Or are most people underdosing without realising it?

The PEMF Podcast dive into what photobiomodulation really means (and why it’s not just “red light therapy”), the three core biological mechanisms behind its effects, and why anti-inflammatory outcomes are the most consistently supported in the research. James also shares inside insights from testing popular devices, discusses why masks and blankets often miss the mark, and explains how proper dosing is more like cooking than simply multiplying power by time. A must-listen for anyone serious about red and near-infrared light therapy especially before buying your next device.
