The Weight of Looking Down
Your head weighs about 12 lb. Tilt it toward a phone and the load on your neck multiplies. Drag the angle.

Effective load on the cervical spine
At 30°, your neck supports about the weight of an 8-year-old child — roughly 3× your head's resting weight.
Over a day: at this angle, two hours of phone time loads your neck the way carrying a heavy backpack would — just on the small muscles never built for it.
Why the load climbs so fast
Your head is a lever. The further it tips forward of your spine, the more force the muscles behind it must generate to hold it up.

~12 lb
Balanced over the spine, your head weighs about what it weighs — 10 to 12 pounds. The muscles barely work.

Texting tilt (30°)
~40 lb
The typical angle for reading a phone. The effective load roughly triples to about 40 pounds of pull on the neck.

Full tilt (60°)
~60 lb
Head dropped fully forward, the load reaches about 60 pounds — five times resting, on muscles never designed for it.

Time at angle
2–4 hrs/day
Many people spend hours a day with the head tilted forward. Sustained, that strain is linked to neck pain, headaches, and early wear — "text neck."
Reviews on text neck & cervical posture
The numbers are illustrative, but the lever is real: small angle, big load, repeated for hours. The fix is boring and effective — raise the phone toward eye level, take breaks, and most of all, spend fewer hours looking down in the first place.
Lift your eyes. Your neck — and your life — is up here.
