Red light therapy penetration depth and more… With Tom Kerber

In this episode, I'm speaking with Tom Kerber, a fascinating entrepreneur with a great deal of knowledge and experience (particularly on the engineering side) in the field of photobiomodulation, (aka modifying biology with light). Approximately 20 years ago, a series of professional and personal events led Tom to shift his career from electronic development to LED device development (like the small blue light device your dentist uses to cure fillings…yes, Tom invented that!).  In part 1 of this two-part series, Tom and I discuss some of the most pressing questions about red and near-infrared light therapy with a focus on how different devices penetrate the body and affect deeper tissues, along with light therapy applications and case studies.  Tom has been developing tools and equipment to do a lot of sophisticated experimentation on penetration depth of red and near-infrared light (which is a much-needed contribution to the field), so I invited him onto the show to discuss his work, which evolved into a 2-part conversation.
