You know how great it feels to succumb to the lures of a nap. Turns out that daytime snoozing could be even more beneficial than you know. Sleep stints of 45 to 60 minutes can boost memory by fivefold, finds a new study published in the journal Neurobiology of Learning and Memory. Tell that to a partner who thinks you're just being lazy.
Previous research has shown the impact of sleep on memory, and the theory is that certain kinds of memory content are "consolidated" during sleep, or moved from short- to long-term memory, which could make room for new information.

Hit a couch rather than a bed, so you don't get too comfy, keeping the lighting dim rather than pitch black so your brain doesn't think it's bedtime. Oh, and consider having a cup of coffee before crashing if you can only snooze about 20 to 30 minutes; that's how long caffeine takes to kick in, so you'll wake up soon as the caffeine takes effect and feel all refreshed.
