Can Light Act Like Estrogen? Red Light, Cognition & Mood || Episode 18

In this episode of Menopause Unscripted, Dr. Heidi is joined by Genevieve Newton of Fringe to unpack what the science actually says about red and near-infrared light therapy (RLT/LT) for brain fog, cognition, mood, and overall cellular health during perimenopause and menopause.The conversation moves from foundational mechanisms—how light works at the mitochondrial and cellular level—to emerging research comparing light’s effects with estrogen, and why some women report cognitive clarity, mood shifts, and energy changes with consistent use. The episode also explores the gut–brain connection, potential combination strategies (including creatine), and how to think about red light therapy as a “supplement” rather than a miracle cure.Key topics include:Brain fog and cognition in midlife and older womenRed light therapy vs. estrogen effectsCellular and mitochondrial mechanisms of light therapyGut–brain connection and metabolic healthRLT, mood, and depression researchSunlight vs. red light therapy and skin safetyPractical frameworks for using RLT responsiblyReferenced research includes peer-reviewed studies on photobiomodulation, cognition, depression, brain fog, and gut–brain signaling.🎧 Support the show & join the community:Patreon → https://patreon.com/HeyDrHeidi📲 Follow the show:Instagram & TikTok: @menopause.unscripted🔗 Connect with Dr. Heidi:Website → https://www.heydrheidi.comInstagram & TikTok: @heydrheidi🎙️ Want to be on the show?Email: [email protected] by Stray Kat StudioProducer: Katherine DonovanSupport the show
