In this episode I interview Scott Zimmerman who is the inventor or the NIRA light bulb. This first true full spectrum light bulb that has a spectral analysis all the way out the 3000 nm.  We discuss the importance of the infrared spectrum for health and how this deficiency can be related to many disorders in the human body. We discuss how we are living in the most photon deficient time in modern history and how this can lead to chronic disease. Scott is an engineer who has published many research papers on light and physiology.
