The Little Book of Phone-Free Sleep: The Science of Screens, Light, and the Sleeping Brain

You already know that scrolling in bed is bad for sleep. But the real story is both simpler and more surprising than a simple ban on blue light. In this concise, evidence-informed guide, science writer Julian Foss Reyner distills decades of research into the subtle ways screens hijack your brain’s ancient sleep machinery. You’ll learn how the light from a phone tricks your internal clock into thinking it’s still daytime, why the dopamine hits of social media make it nearly impossible to put the device down, and how even the content you consume can leave your mind wired long after you turn off the screen. More importantly, this book offers practical, gentle strategies for reclaiming a phone-free wind-down—without shame or absolutism. Whether you are a habitual late-night scroller or a parent trying to set a better example, you’ll find realistic steps to protect your sleep without throwing your phone into a river.
