Explanation

  • To delay making a decision until the next day, allowing time for thought and rest, believing that a clearer perspective might emerge after sleeping.

Origin

  • The idea that sleep helps with decision-making and problem-solving is ancient.
  • The expression itself likely became common because people often find clarity or a fresh perspective after a night's rest, away from the immediate pressure of the decision.
  • It leverages the natural break provided by sleep for mental processing.

Alternatives

  • Let me crash on it. (Less common, very informal)
  • I'll give it the overnight test.

More Formal:

  • Allow me until tomorrow to finalize my decision.

Situational Appropriateness
