The revolutionary science showing how a simple upward shift in posture, breath, and attention can restore vitality in a heads-down world. Something is wrong. You feel it in your neck, your energy, your focus, your sleep. You feel it in the persistent sense that you're operating below your potential—even when every test comes back normal. We've spent decades blaming stress, aging, burnout, and lack of willpower. But what if the real problem has been staring us in the face—or more accurately, beneath it? In Look Up, three leading doctors reveal a hidden health crisis affecting billions of people worldwide: Tech Posture Syndrome. Created by years of downward screen use, sedentary behavior, compressed breathing, and chronic nervous-system overload, this modern epidemic quietly undermines physical health, mental clarity, emotional resilience, relationships, and long-term vitality. Drawing on cutting-edge neuroscience, biomechanics, respiratory physiology, embodied cognition, and more than sixty years of combined clinical experience, Dr. Gilles A. LaMarche, Dr. Jeff Langmaid, and Dr. Jason A. Deitch present a powerful new framework for understanding health in the digital age. At the center of their approach is a deceptively simple practice: Look Up. With practical tools including the 20-Second Lift, the Sensory Diet, the Look Up Protocol, and the 30-Day Look Up Challenge, readers will learn how to improve posture, regulate stress, restore energy, deepen breathing, strengthen social connection, and reclaim the vitality modern life has been stealing. Part science, part manifesto, and part practical guide, Look Up offers an inspiring vision of a future where technology works with human biology instead of against it—and where small daily adjustments create extraordinary lifelong results. The heads-down world is making us sick. It's time to look up.
