How can I help someone when they keep going for ages and then suddenly have no energy left?

People come here to understand why something in everyday life feels harder, different or more costly than it should — and what might make it work better.

Short answer

Long stretches of effort can hide rising recovery needs until capacity drops.

What this can look like

They may keep going because stopping feels risky, then suddenly have no attention or energy left.

Why it can happen

Encourage planned pauses and protect the right to stop before the person has run out.

What might help

Encourage a planned pause before the crash point. A return note can make stopping feel safer because the next step is waiting.

What the research helps explain

Executive-function research describes attention, working memory and flexibility as limited, context-sensitive processes. Good support changes conditions and asks permission; it does not turn a pattern into a label.

What can vary

Health, stress, sleep, task design and personal preference can all matter. Do not infer a diagnosis or speak for the person.

For this situation

For you, notice effort and recovery, not only output.
