What happens when you deprive yourself of blue light?

from Defiant Health Radio with Dr. William Davis · host William Davis, MD

Science journalist Lynne Peeples did something extraordinary: She spent 10 days in a nuclear bunker exposed only to dim red light but no blue or other visible wavelength of light. She also rid the space of all clocks or other time-indicating devices and even avoided having any human contact. What she learned opened up numerous questions on how to best manage our day-to-day light exposure, wavelengths, and the implications they have on the quality of sleep, our moods, even various aspects of health and performance. After these sorts of unique experiences, along with discussions on circadian rhythms with numerous scientists working on this topic, Lynne comes to some unique conclusions. Lynne is the author of the book “The Inner Clock: Living in Sync with Our Circadian Rhythms” in which she explores the role of purposeful management of your circadian rhythm, your inner clock, for management of energy, focus, and mood. Here, Lynne and I talk about her novel insights, along with practical advice on how to better manage your light exposure and circadian rhythm. Lynne's book, The Inner Clock on Amazon:https://www.amazon.com/Inner-Clock-Living-Circadian-Rhythms/dp/0593538900/ref=tmm_hrd_swatch_0Lynne's YouTube channel: https://www.youtube.com/hashtag/lynnepeeples?app=desktopSupport the showYouTube channel: https://www.youtube.com/@WilliamDavisMDBlog: WilliamDavisMD.comMembership website for two-way Zoom group meetings: InnerCircle.DrDavisInfiniteHealth.comBooks:Super Gut: The 4-Week Plan to Reprogram Your Microbiome, Restore Health, and Lose WeightWheat Belly: Lose the Wheat, Lose the Weight and Find Your Path Back to Health; revised & expanded ed
