Among the 39 healthy adults who were evaluated in the study, those who slept for an hour and a half during the day performed better on a post-nap cognitive exam than did those who remained awake.
All participants were initially assigned a "hard learning" morning task for which all performed roughly the same. Half the group then took a nap while the others stayed awake.
