Anatomy: what the neck actually is
The neck, or cervical spine, is supported by many small muscles plus the upper trapezius, which together hold up and move a head that weighs around 10-12 pounds — a load that increases sharply the further forward the head tilts.
Why necks get tight
- "Tech neck." Looking down at phones and screens for hours multiplies the effective load the neck muscles carry with each inch the head shifts forward.
- Stress. The upper traps are a common place to unconsciously hold tension.
- Sleeping position. An awkward pillow height or sleeping posture is a common reason the neck feels stiffest first thing in the morning.
- Prolonged one-sided posture. Holding a phone to one ear or favoring one side while working can leave that side chronically tighter.
Best neck stretches
Start with the side bend, then add the others depending on where the tightness sits.
How long and how often
20 seconds per side, repeated 2 times, is the standard recommendation and matches ExtendTimer's neck preset by default. Daily is fine, especially for anyone spending long hours on a phone or screen.
