Napping empties your brain’s inbox

Walker’s team showed that fact-based memories are temporarily stored in a region of the brain called the hippocampus before being sent to the brain’s prefrontal cortex, which may have more storage space.

Clearing brain’s inbox

“It’s as though the email inbox in your hippocampus is full and, until you sleep and clear out those fact emails, you’re not going to receive any more mail. It’s just going to bounce until you sleep and move it into another folder,” Walker said in a statement.

I’m very much in favour of any research that recommends napping.
