Your head weighs around 5 kg. As it moves forwards and down towards your phone, the leverage changes, and the demand on your cervical spine can increase dramatically.
At a 60-degree angle, one biomechanical model estimated the load at the equivalent of approximately 27 kg.
Now consider how often this position appears throughout your day: reading messages, answering emails, scrolling, working or simply waiting for something to load.
Your body adapts. Muscles around the neck and shoulders work harder, the upper back becomes less mobile, and the connective tissues begin to organize around a posture repeated for hours. Eventually, you may put the phone away while your body continues holding the same shape.
This isn’t an instruction to sit perfectly straight. No posture becomes a problem simply because you visit it. Difficulty begins when you remain there for too long and lose the freedom to move easily out of it.
Bring the screen closer to eye level. Change position regularly. Move your shoulders, ribs and spine, not only your neck. Your body needs variation more than correction.
How many hours a day do you think your head spends looking down?
