What should be done to avoid bending the neck repeatedly while working?

Correct answer: Keep material or screen at proper height

Direct answer: A, keep the material or screen at a proper height. Repeated neck bending puts the head and neck in an awkward position and can cause muscle strain, discomfort and fatigue. Raising the screen, book or work material to a suitable level helps the neck remain nearer to a neutral, comfortable position. Option A is correct because it directly changes the working height and reduces repeated bending. Option B is wrong because reducing light can make the worker bend closer and can cause visual strain. Option C is wrong because placing the chair far away encourages leaning or stretching and does not solve the height problem. Option D is wrong because hiding tools increases searching and awkward movement. The reasoning is: identify the painful repeated movement, adjust the height of the object, and keep the head and neck aligned comfortably. Memory cue: to protect the neck, “raise the work, do not bend the neck.”
