Quick answer

Screen related neck pain is usually a load and duration problem. Raise the screen to eye level, bring the keyboard close, and interrupt sustained positions every 30 to 45 minutes with brief movement.

If your neck is comfortable on a Sunday and sore by Wednesday afternoon, the working environment is worth examining before anything else.

The laptop problem

A laptop forces a compromise: either the screen is too low or the keyboard is too high. Working like this for hours loads the neck extensors continuously. A laptop stand with an external keyboard and mouse solves most of it for very little cost.

Practical adjustments that help

Position the top of the screen at roughly eye level, about an arm's length away. Support your forearms so the shoulders are not held up. Keep frequently used items within easy reach so you are not repeatedly twisting. If you take calls, use a headset instead of holding the phone against your shoulder.

Movement beats posture perfection

There is no single perfect posture. What matters is that your position changes regularly. Set a recurring reminder and use one or two of the exercises below.

Exercise programme

Work within a comfortable range. Mild discomfort is common, sharp or increasing pain is not.

1. Desk Chin Tuck and Rotate

Beginner

Starting position: Sitting upright, feet flat on the floor.

  1. 1Make a small chin tuck to lengthen the back of your neck.
  2. 2Hold the tuck and slowly rotate your head to one side.
  3. 3Return to the middle, release and repeat to the other side.
Every hour of screen work 5 per side

Suitable for: Desk based workers with mid afternoon neck stiffness.

Stop if you feel dizzy or get arm symptoms.

2. Doorway Chest Stretch

Beginner

Starting position: Standing in a doorway with forearms on the frame at shoulder height.

  1. 1Step gently forwards with one foot.
  2. 2Allow a comfortable stretch across the front of the chest.
  3. 3Keep your ribs down and avoid arching your back.
2 sets 20 to 30 seconds

Suitable for: Rounded shoulder positions from long screen sessions.

Ease off with any shoulder pinching pain.

When to stop and get assessed

  • Any exercise that produces dizziness, headache or arm symptoms.

When to see a physiotherapist

If workstation changes and exercises do not reduce your symptoms within a few weeks, an assessment can determine whether joints, muscles or nerve sensitivity is the main driver.

Frequently asked questions

Can bad posture really cause neck pain?+

Sustained positions matter more than posture shape. Long unchanged positions load tissues, which is why movement breaks help.

Should I use a standing desk?+

It can be useful if you alternate sitting and standing. Standing all day may create its own problems.

Do neck braces or collars help?+

Generally not for everyday mechanical neck pain, as they reduce movement and can prolong stiffness.

How high should my monitor be?+

Roughly with the top of the screen at eye level and about an arm's length away.
