Summary
In this episode, I’m speaking with Dr. Mark Cronshaw, a highly respected expert in the field of photobiomodulation (PBM) – what most people commonly think of as red light therapy.
This is the first of many podcasts with Dr. Cronshaw, who is one of the most brilliant and knowledgeable experts I’ve had the pleasure of connecting with on this topic. Our conversation goes deep into the science of photobiomodulation—there are some practical pearls that Dr. Cronshaw discusses, but be prepared for deep, nuanced, and technical scientific discussion about light therapy.
WARNING: Please be aware that this conversation with Dr. Cronshaw is NOT just a simple practical how-to guide of “go buy this device and use it this way.” This is a podcast series that intends to go deep into the scientific, technical, and theoretical nuances of PBM science. So it’s NOT for everyone. If you just want a simple practical how-to guide, we will eventually get there, but there are several hours of geeky technical science stuff before we get there. These podcasts with Dr. Cronshaw are for people who want to nerd out on PBM science. So please don’t say I didn’t warn you! :)

| 0:00.0 | Hey, this is Ari. Welcome back to the Energy Blueprint podcast. With me in this episode is Dr. Mark Cronshaw, who is one of the world's foremost experts in the field of photo biomodulation. This is the interaction of light with biology. Photo, light, bio |
| 0:24.8 | biology and modulation is what it sounds like. This is more commonly known or thought of as being |
| 0:31.8 | synonymous with red and near infrared light therapy. It's technically broader than just red |
| 0:37.0 | and near infrared wavelengths. |
| 0:38.3 | It includes many different wavelengths. But this whole field of red and near infrared light |
| 0:43.8 | therapy has really exploded in recent years. When I wrote my book, The Ultimate Guide to Red |
| 0:49.8 | Light Therapy back in 2017, this was really a very fringe topic. Not a lot of people were talking about it. |
| 0:57.3 | Very few people had heard of it. If I brought it up to people most, I'd say 99% of the time, |
| 1:03.0 | most people had never, never even heard of the idea of red light therapy or the idea that red and |
| 1:07.7 | near infrared light had some unique effect on human biology. |
| 1:12.3 | It has since become totally mainstream. |
| 1:15.2 | We see it everywhere popping up in different facilities, med spas and gyms, and we see it in the media and on TV. |
| 1:23.8 | Everybody knows what red light therapy is. |
| 1:25.9 | It's fully gone mainstream, from fringe to mainstream. |
| 1:28.9 | So my timing with the book that I wrote, which was a book really, you know, I was passionate about |
| 1:35.5 | this field for many, many years. I had become aware of it, probably at that time I was already |
| 1:41.6 | aware of it for at least seven or eight, maybe |
| 1:44.8 | 10 years of this sort of unique effect of red and near infrared light. I knew clinicians. |
| 1:51.2 | My older brother, who's a chiropractor, was using lasers in his practice. And so I was kind |
| 1:57.5 | of following this emerging science for many, many years prior to the existence |
| 2:02.2 | even of LEDs. |
| 2:03.7 | And I would reach as soon as LEDs, I wouldn't say prior to the existence of LEDs, but prior |
