What should you know about mental exhaustion from work?

You may notice reduced focus, forgetfulness, irritability, headaches, low motivation, or feeling overwhelmed by ordinary decisions. Long hours, constant availability, conflict, low control, unclear expectations, and poor sleep can all add pressure. When work-related strain becomes persistent and affects functioning, it may fit burnout, but fatigue can also reflect anaemia, dehydration, infection, kidney disease, coeliac disease, or other health problems.

Alcohol can worsen sleep and energy even when it seems to offer short-term relief. A clinician can separate work stress from a medical or mental-health condition.

Take genuine breaks, protect a regular sleep window, eat regularly, drink enough fluid, and use a brief written priority list to reduce mental load. Discuss workload, deadlines, boundaries, or leave with a manager or occupational-health service when that is safe. Keep a note of symptoms, work patterns, sleep, and substances so an appointment is more useful.

Arrange medical advice if exhaustion continues despite recovery time, keeps returning, or limits safe driving, work, or self-care. Do not assume the cause is only your job.

Seek emergency help for chest pain, severe breathing trouble, fainting, sudden confusion, new weakness, or thoughts of self-harm. Get prompt medical advice for rapidly worsening exhaustion, marked dehydration, persistent fever, black or bloody stools, or inability to perform basic activities.

Could a medical condition, medicine, sleep problem, or substance be contributing? Do I need an examination or tests? How can I manage work safely while recovering, and what symptoms should trigger urgent help?
