Text Neck” Explained – What Your Phone Is Doing to Your Neck
This image powerfully shows how head position directly multiplies the load on your cervical spine. The human head weighs about 4–5 kg in neutral posture, but as the head tilts forward, the effective load on the neck increases dramatically.
🟢 0° – Neutral Head Position (≈ 5 kg)
When your ears are aligned over your shoulders, the cervical spine carries only the true weight of the head. Muscles work efficiently, discs are evenly loaded, and stress on joints is minimal. This is the safest and most energy-efficient posture.
🧠 Why This Matters
The neck is designed for mobility, not sustained load. Holding the head forward for long periods causes cumulative micro-stress that builds silently over time. This is why neck pain often appears gradually rather than suddenly.
