It looks as though a nap can help increase learning capacity, perhaps by clearing out a backlog of facts and making room for more. From the article:
“It’s as though the e-mail inbox in your hippocampus is full and, until you sleep and clear out those fact e-mails, you’re not going to receive any more mail. It’s just going to bounce until you sleep and move it into another folder.”
If you couple this with the boost in growth hormone that you can obtain from the same nap (a topic I want to post more on soon), it seems that it may be well worth scheduling a daily siesta.
