Your Phone Is Rewiring Your Brain: Blue Light, Flicker & EMFs Explained | Tristan Scott

I’ve spent years questioning food, farming, and the systems that feed us, but I had never once questioned the glass and the light I stare at every day. I thought it was just the apps trying to keep us hooked. I didn’t realize the hardware itself was engineered to do the same thing.

Tristan Scott is an electrical engineer and the Head of Hardware and Marketing at Daylight Computer Co. He’s taken a deep dive into how blue light, flicker, and EMFs affect our biology, and this conversation changed how I see the tech around me. He helped me understand that our screens are designed, intentionally or not, to hijack our attention and stress our nervous systems. From the form factor to the light spectrum to how and where we use them, these devices are rewiring our brains.

We talk about the Las Vegas effect, why your phone is like a slot machine, why natural light matters, and how hard it is to put the device down when the environment itself is engineered to keep you on it. But this isn’t about going back to the stone age. It’s about creating a new relationship with tech, one that works with our biology, not against it.

Key Takeaways

Screen Light Is Biological - Blue, flickering light disrupts dopamine and circadian rhythms.

Hardware Matters - Device design itself drives addiction and overstimulation.

Flicker Fatigue Is Real - Invisible screen flicker stresses the nervous system.

EMFs Affect Physiology - Wireless signals impact cellular and mitochondrial health.

Indoor Tech, Outdoor Body - Tech built for indoors clashes with outdoor-evolved biology.

Designing Healthier Tools - The Daylight Computer supports natural light and focus.
