Assessment of stresses in the cervical spine caused by posture and position of the head
Kenneth Hansraj's biomechanical model calculates how the load on the cervical spine climbs as the head tilts forward — from about 10–12 lbs at neutral to 27 lbs at 15 degrees, 49 lbs at 45 degrees, and 60 lbs at 60 degrees. It is the study behind nearly every 'text neck' headline since 2014.
The Look Up read
This is the book's 60-pounds-at-60-degrees figure — a static model showing the direction of loading, not a measurement of any one person's neck. The angle is the variable, and the angle is a choice.
The Look Up view
Direction true, number illustrative: 60 pounds is a static model pointing at the load, not a scale reading — the angle is real, and the angle is the choice.
☀ Use it — At your next phone check, notice the tilt before the ache: raise the screen toward eye level and the load drops with the angle.
