The Digital Hunch ebook

The human head weighs about 10-12 pounds. But when you tilt it forward 60 degrees to look at your phone, the force on your neck increases to 60 pounds. Physiotherapist Rachel Prentiss explains the biomechanics of "Text Neck" in "The Digital Hunch." Prentiss warns that we are evolving into a hunched species. She details the long-term consequences: early arthritis, reduced lung capacity, and chronic headaches ("cervicogenic headaches"). It isn't just about pain; bad posture affects serotonin levels and confidence. The book provides a "Tech-Rehab" plan. Prentiss demonstrates simple exercises like "Chin Tucks" and "Thoracic Extensions" to reverse the curve. She advocates for holding phones at eye level (the "T-Rex arms" position) and changing how we interact with technology to protect the structural integrity of our bodies.
