Most people with migraines are warned about one thing: bright light. Screens. Sun glare. Fluorescent bulbs. But what if the real issue isn’t just too much light, what if too little light is just as destabilizing for your brain? In this episode of Migraine Heroes Podcast, host Diane Ducarme unpacks the overlooked relationship between light, brain chemistry, circadian rhythm, and migraine vulnerability. Blending modern neuroscience with Eastern wisdom, this conversation reframes light not as an enemy to avoid, but as a biological signal your brain deeply depends on. You’ll discover why migraine brains struggle with both overstimulation and deprivation, and how living too far on either end quietly lowers your migraine threshold. In this episode, you’ll learn: 💡 Why both excessive light and insufficient light can trigger migraine attacks, even though most advice only focuses on brightness 💡 What neuroscience reveals about how light regulates pain pathways, sleep hormones, and brain blood flow 💡 Why indoor living, winter darkness, and screen-heavy days confuse the migraine brain more than you realize 💡 How Eastern medicine has long understood light as a regulator of energy, rhythm, and mental clarity 💡 Practical ways to use light intentionally, not aggressively to support brain stability, mood, and resilience This episode is not about hiding in the dark or forcing yourself into harsh sunlight. It’s about finding the right light rhythm, one that calms your nervous system instead of shocking it. If you’ve ever felt worse in winter, foggy after days indoors, or paradoxically triggered by both sunshine and darkness, this episode will help you finally make sense of why. 🎧 New episodes every Monday and Wednesday 🔗 Discover our work on migraineheroes.com References: Migraine Photophobia and Retinal Pathways (Noseda et al., Nature Neuroscience, 2016): Noseda and colleagues showed that migraine-related light sensitivity originates in cone-driven retinal pathways that directly activate pain circuits in the brain, explaining why even normal light can feel painful during migraine.
