Sleeping after learning improves memory consolidation more than staying awake to keep studying.

Is it true that sleeping after learning improves memory consolidation more than staying awake to keep studying?

Partly. Several studies in young children and infants report that sleeping or napping shortly after learning improved later retention compared with staying awake, and one forum answer cites studies favoring wakeful rest over post-study mental exertion. A study in older adults, however, found no significant sleep benefit on consolidation or relearning, so the evidence covers only parts of the claim and points both ways.
