"Mid-afternoon naps are an integral part of most cultures, and scientifically proven to be good for you."
"A needed rest can make you feel better and also improve your mood. After having the extra amount of sleep, a person will notice that they will be more productive and energetic. Numerous studies have shown that short 10-20 minute naps are the most effective when midday fatigue hits. Improvements in alertness, productivity and mood have all been shown to improve with this type of snooze.
Though there are some of us who are just not the napping kind, if you can reap those benefits, find a cozy spot for 10 minutes or so on National Napping Day."
