220. Circadian Rhythms and Light with Deanna Minich, PhD
Light is one of the most powerful signals regulating the body's internal clock, influencing sleep, hormones, metabolism, mood, and overall health. In this episode, we explore how morning light, daytime brightness, evening darkness, and nighttime habits can either strengthen or disrupt circadian rhythm. We also discuss practical ways to get your light right and honor the night in a world filled with screens and artificial illumination. Joining us is Dr. Deanna Minich, a pioneering nutrition scientist and thought leader with more than 25 years of experience bridging science, spirituality, and art; she serves as Chief Science Officer at Symphony Natural Health, is a Personalized Lifestyle Medicine Institute board member, and received the Institute for Functional Medicine's 2025 Linus Pauling Award.
