A nap is a short period of sleep, typically taken during daytime hours as an adjunct to the usual nocturnal sleep period.
Naps are most often taken as a response to drowsiness during waking hours.
Cultural attitudes toward napping during the work day vary. In many Western cultures, children and the elderly are expected to nap during the day and are provided with designated periods and locations to do so.
In these same cultures, most working adults are not expected to sleep during the day and napping on the job is widely considered unacceptable.
Other cultures serve their largest meals at midday, with allowance for a nap period (siesta) afterwards before returning to work. This happens mostly in boarding houses.

Benefits
☆Napping is physiologically and psychologically beneficial. Napping for 20 minutes can help refresh the mind, improve overall alertness, boost mood and increase productivity.
☆Napping may benefit the heart. Research shows that people who take naps often have 37% lower risk of heart-related death.
☆Naps are as good as a night of sleep for some types of memory tasks. Research shows that naps can improve certain memory functions and that long naps are more effective than short ones.
To measure the effectiveness of the naps, check for alertness, response time, and other cognitive skills.
