Meaning
To postpone making a decision until the following day.
Cultural Background
In American business culture, 'sleeping on it' is respected as a sign of a 'shrewd' or careful negotiator. It is often used to resist high-pressure sales tactics. British speakers use this frequently to avoid direct confrontation. Instead of saying 'No,' they might say 'Let me sleep on it' to give themselves space to decline later. While not a native Japanese idiom, the concept aligns with 'Ringi' (consensus building). Taking time to 'sleep on it' is seen as respectful to the group. Germans value 'Gründlichkeit' (thoroughness). Sleeping on a decision is seen as a necessary step to ensure all facts have been considered.
The 'Polite No'
If you want to say 'no' but feel awkward, say 'Let me sleep on it.' It gives you 24 hours to write a polite email instead of being put on the spot.
Don't wait too long
If you say you'll sleep on it, you MUST give an answer the next day. If you wait three days, it's no longer 'sleeping on it'—it's just ignoring them!
