Mental load: why you’re exhausted even when you “did nothing”

Mental load is invisible work: remembering, planning, deciding and checking. No one sees it from the outside, but it drains you as much as physical work. We look at how to recognize the mental load, why it wears you out and how to share invisible tasks without arguments.
Questions and answers
What does mental load mean in simple terms?
It’s the invisible work in your head: noticing that something needs doing, finding options, making a decision and making sure it all gets done. No one sees it from the outside, but it uses up your attention and energy all day.
How is mental load different from burnout?
Mental load is the amount of tasks you hold in your head. Burnout is a state of exhaustion that can develop if that load stays high for a long time and there isn’t enough recovery.
Mental exhaustion: what can you do?
Get all your tasks out of your head and onto paper, cut down the number of daily decisions, hand off tasks in full and leave time for sleep and rest. If the fatigue doesn’t go away for weeks, it’s worth discussing with your doctor.
What is invisible work?
It’s the preparation and keeping track behind the visible tasks: remembering birthdays, doctor’s appointments, groceries that are running low. It’s rarely noticed, so it often becomes a source of misunderstanding in families and at work.
