You keep pushing through one more email, one more scroll — until the screen blurs, colors pulse, and the edges of your vision begin to shimmer. It’s not just fatigue. In a world bathed in blue light, your brain is overstimulated, your nervous system on edge, and your eyes are paying the price.

In this episode of The Migraine Heroes Podcast, host Diane Ducarme unpacks how modern light exposure hijacks your body’s natural rhythms. Drawing from both Western neuroscience and Eastern medicine, she reveals how screens, stress, and overstimulation keep your brain in “on” mode — and what you can do to calm the circuitry.

You’ll discover:

💡 How blue-wavelength light activates the same neural pathways that control alertness, pain, and stress

💡 Why constant screen time disrupts melatonin, sleep, and recovery — making your brain more sensitive to triggers

💡 Simple, restorative practices to help your nervous system down-shift from reactive to regulated

You’ll also learn how Traditional Chinese Medicine sees the eyes as the “windows of the Liver,” meaning that overstimulation drains your body’s Qi and depletes the calm you need to heal.

If your migraines, insomnia, or tension rise with every notification — this episode will help you reclaim the calm beneath the glare.

• Exposure to Blue Wavelength Light Increases Subsequent Functional Activation of the Prefrontal Cortex: A 2016 study in Sleep (Alkozei et al.) found that short-term exposure to blue light boosts prefrontal cortex activity during working-memory tasks, showing how blue light can heighten cognitive alertness—sometimes at the expense of relaxation and sleep.

For women, men, and children who suffer from migraine disease, Migraine Heroes is your go-to resource for understanding, managing, and overcoming migraine attacks.

We cover all types of migraines and related headaches, including primary and secondary migraines, chronic migraines, and cluster migraines. We dive deep into the complexities of migraine with aura and migraine without aura, as well as rarer forms like hemiplegic migraine, retinal migraine, and acephalgic migraine (silent migraine). Our discussions also extend to cervicogenic headaches, ice pick headaches, and pressure headaches, which often mimic migraine or contribute to overall migraine burden.
