About this podcast

Join Andrew Huberman as he welcomes Dr. Glen Jeffery, a distinguished Professor of Neuroscience at University College London, for an illuminating discussion on how different wavelengths of light profoundly impact our cellular health and overall well-being. Dr. Jeffery, a leading expert in the field, unpacks the science behind long-wavelength light (red, near-infrared, and infrared) and its remarkable ability to penetrate the body and brain, enhancing mitochondrial function. Discover how this can lead to improvements in metabolism, eyesight, blood glucose regulation, mood, and hormone balance. The conversation also critically examines the harmful effects of short-wavelength light from LED bulbs on mitochondrial health and underscores the vital importance of balanced, full-spectrum light for optimal health. Dr. Jeffery provides practical, actionable insights on leveraging natural and artificial light sources to boost your metabolic function, enhance vision, and promote longevity.
