What should you know about digital fatigue?

Online work can combine close visual focus, static posture, interruptions and constant decisions. That combination may leave you mentally drained, heavy-eyed, less attentive or slower to complete familiar tasks. Poor sleep, dehydration, emotional strain and an unsuitable workspace can add to the feeling. Fatigue is a symptom, not a diagnosis: it can also occur with anaemia, infection, burnout, kidney disease or other health conditions.

Break long sessions into shorter periods and change focus regularly. Stand, stretch your neck and shoulders, blink deliberately and keep water nearby. Reduce unnecessary alerts, use a comfortable viewing distance and avoid working from bed. Keep a steady sleep routine and record your energy, sleep, meals, medicines and screen demands for several days. If possible, discuss realistic workload changes with your employer or school.

Book a GP consultation when fatigue lasts, worsens, limits ordinary activities or is present even on days with little screen use. Prompt assessment is also sensible with unexplained weight change, persistent fever, breathlessness, fainting, marked thirst or changes in urination. Sudden weakness, severe breathlessness, chest pain or confusion needs urgent care.

What causes should we check besides screen-related strain? Could my sleep, medicines or mood be contributing? Which changes should I monitor before follow-up?
