In a neutral position, the human head places about 5 kilograms of force on the cervical spine. But when the head tilts forward to look at a phone, that load increases dramatically, reaching the equivalent of 27 kilograms at a 60-degree angle.
This excess pressure strains muscles, ligaments, and spinal discs, contributing to neck pain, stiffness, headaches, and long-term postural problems. Over time, repeated stress can accelerate disc degeneration, nerve irritation, and abnormal spinal curvature, a condition often called βtech neck.β
Experts recommend bringing screens up to eye level instead of lowering the head. This simple habit reduces spinal load, protects neck health, and helps prevent chronic pain linked to prolonged device use.
