Brief Deactivation Restores Attention
Vigilance decays over a long task. Short, complete breaks restore it; “breaks” spent on a screen do not.

solidHow strong is the evidence?
Good evidence behind it, but fewer people have checked it independently.

Why it works
The deficit is in sustained goal activation, and briefly deactivating the goal resets it. Feeds do not deactivate anything.
What to do about it
- Every 60–90 minutes take five minutes away from screens. Outside beats inside; green beats grey.
- Move. A walking break outperforms a sitting break for what follows it.
- Take the break before you need it. A break taken after the decline has set in recovers less.
Where people go wrong
Scrolling as a break — it is task-switching with worse content, and it restores nothing.
