026: Photobiomodulation, Circadian Biology, and Consciousness with Sarah Turner

Light is fundamental to our existence as human beings; it has been a part of our development from the beginning of our time on earth and it continues to impact almost every part of our lives in ways that we are not even aware of. At least according to Sarah Turner, an expert in photobiomodulation and the co-founder and Head of Science at CeraThrive, the red light therapy system targets the gut-brain axis. Sarah is a scientist through and through, but her interest has oscillated from the mechanical end of the spectrum (through her work in the pharmaceutical industry) to the holistic and alternative end (through the studying she did when she became disillusioned with the pharmaceutical industry). She is now in the process of finding her optimal positioning somewhere between the two, and in today’s episode, Sarah shares a wealth of mind-boggling information about consciousness, circadian biology, and photobiomodulation that will cause you to rethink everything you thought you knew, and realize how much more there is still to be discovered!
