Using Red Light to Improve Metabolism & the Harmful Effects of LEDs | Dr. Glen Jeffery

In this episode of the Huberman Lab podcast, Dr. Andrew Huberman interviews Dr. Glen Jeffery about the impact of light, specifically red, near-infrared, and infrared light, on various aspects of health. They discuss how different wavelengths of light affect mitochondrial function, skin health, eyesight, and blood sugar regulation. Dr. Jeffery explains how long-wavelength light is absorbed by water in mitochondria to enhance ATP production and protect against damage from LED bulbs and screens. The conversation covers the importance of sunlight exposure, the surprising benefits of UV light, and findings correlating sunlight with longevity. They also address practical applications of red light therapy, including whether to close eyes during use, and the potential for long-wavelength light to penetrate the body and improve organ health, even reaching the brain. The discussion also highlights the potential dangers of excessive short-wavelength light from LEDs and strategies to balance light exposure for optimal health.
