The Blue Light Effect

Can't sleep? It's not your fault. It's your screens.

Every night, millions of people climb into bed exhausted—only to lie awake, minds racing, while the glow of a smartphone, tablet, or laptop whispers to their brain that the sun is still high. They wake up groggy, rely on caffeine to function, and wonder why sleep feels so elusive.

The Blue Light Effect reveals the hidden culprit behind this modern epidemic: the specific wavelength of light that screens emit, which hijacks your internal clock and suppresses the hormone you need to sleep. Drawing on cutting-edge circadian science, this book explains exactly how blue light disrupts your sleep, mood, metabolism, and long-term health—and gives you a practical, flexible system to fix it, without giving up your devices.

You'll discover:
•Why "night mode" isn't enough—and what actually works
•The simple evening ritual that restores your body's natural sleep signal
•How to build a 30-day protocol for deep, restorative sleep
•Real-life strategies for shift workers, parents, gamers, and frequent travelers
•Morning light, meal timing, and bedroom hacks that amplify your results

If you've tried sleep tips that didn't stick, it's because they missed the master switch: your light environment. This book hands you the tools to reclaim your nights and wake up fully alive.
