Dr. Glen Jeffery, PhD, is a professor of neuroscience at University College London and a leading expert on how different colors (wavelengths) of light impact cellular, organ and overall health. He explains that long-wavelength light (red, near-infrared and infrared) can enter the body and brain to enhance mitochondrial function and thereby improve metabolism, eyesight, blood glucose regulation, mood, hormones and more. We also discuss how short-wavelength light from LED bulbs can impair mitochon
