Most people have a vague sense that their devices might not be good for them—but few understand just how deep the rabbit hole goes. In this fireside talk, Tristan Scott—a former electrical engineer turned health advocate and technologist—pulls back the curtain on the invisible forces shaping our biology: electromagnetic fields (EMFs).

From the wiring in your walls to the 5G towers on your street to the screen in your hand, modern life is saturated with non-native electromagnetic signals. Tristan breaks down why that matters—how these signals interact with our nervous system, disrupt sleep, impact fertility, and interfere with mitochondrial function. More importantly, he offers a path forward.

Now working with Daylight Computer, Tristan is helping to build the first tech products designed to work with our biology, not against it. If you've ever wondered why being outside just feels better—or why staring at a screen all day leaves you drained—this talk might change the way you see the modern world.
