eight months agoJustifying your desire to nap

Ever get that sleepy feeling after lunch? Science has now proven that you should just give in and have that nap.

Apparently having a 90 minute nap during the day helps your brain process information into long term memory, though there won't be any noticeable difference until the next morning.

The researchers found sleep helped overcome interference -- the brain processing new information that interferes with remembering old information learned earlier in the day. Another group of participants in the study taught the same skills, but without the nap showed no improvement in their ability to perform the task.

So next time someone catches you sleeping during the day, have a printout of the journal to wave at them!
