 The midday nap is a pre-school tradition.but is it necessary? Some pre-schools plan to eliminate this downtime to fit in more teaching which could come the expense of learning.Because the study suggests that this news may help kids retain information they learned earlier in the day. The work is published in PLOS ONE.

 
To see how naps affect academic performances researchers taught 40 pre-schoolers between the ages of 3 and 6 to perform a memory task. After a few hours of break time, the children need their stayed-awake or got to nap, sleeping for an average of 77 minutes. Although napping may no significant difference to feelings and sleepiness, it did help enhance memory. When tested later in the day, students who had rested performed better. Even the next day, the children who had napped after the initial lesson still retained more information. The benefit was greatest for students who took naps regularly, not just during the study, which suggests schools may want to keep sleep on the salivas.
