In this episode, I’m excited to share a conversation with Dr. Glen Jeffrey, a leading expert in the science of light and its impact on our health. If you’ve been listening for a while, you know I’ve talked a lot about how light affects our metabolism, mitochondria, and overall healing, but today you’re going to hear the science directly from the source. Dr. Jeffrey and I dive into how different light spectrums—from red and infrared to blue light—can influence everything from cortisol levels to mitochondrial function. This episode is a follow-up to last week’s chat with Dr. Robert Schultz, so be sure to tune in for a deeper understanding of the fascinating ways light shapes our health. Check the show notes for all the links and resources we discuss!
