@the.anatomy.hub2: Why Your Neck Hurts After Looking Down at Your Phone | Tech Neck in 3D Why can your neck start feeling tired or stiff after looking down at your phone? This 3D anatomy video explains how the cervical spine and surrounding muscles support the head during normal posture, and what changes when the head moves forward and downward for long periods. In a neutral position, the head stays relatively aligned above the shoulders and the load is distributed more efficiently. When looking down at a phone, the cervical spine flexes and the muscles at the back of the neck and upper shoulders may need to work harder to support the head. Over time, this increased muscular demand can contribute to fatigue, sensitivity, and stiffness around the neck. This video shows the difference between normal head alignment and prolonged forward-head positioning. For educational purposes only. #TechNeck #NeckPain #ForwardHeadPosture #NeckAnatomy #Anatomy
