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

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 mitochondrial
health and why balanced, full-spectrum light is essential for
health. Dr. Jeffery shares simple yet powerful ways to use natural
and artificial light sources to enhance your metabolic function,
eyesight and longevity. Sponsors AG1: https://drinkag1.com/huberman
