How napping can renew you . . .

 If you’re like the average American, you are

probably sleep deprived.  Inadequate sleep reduces your concentration, alertness, creativity and performance at work.^1,2  It also makes you more prone to make mistakes, feel tired, grouchy, and increases your cravings for sweet and fatty foods.^3,4  

As a nation, we value doing more and place little emphasis on taking breaks, having fun and resting.  In other countries, however, working less, playing more, taking breaks and sleep are cultural norms.  Fortunately, there is a cultural shift taking place that emphasizes working smarter, taking more breaks and even napping on the job! So whether or not you believe that you get adequate sleep, you probably can benefit from adding an afternoon power nap.  

An afternoon nap, or siesta, can help you to improve your mood, alertness, vigor and be your mini vacation to relax and feel rejuvenated.^5,6 It will help you be less prone to mistakes and increase your creativity as well as your job performance.^7,8 In order to reap all of these health promoting benefits, just keep these simple guidelines in mind.  

Take brief naps (i.e. 10 – 30 mins) early in the afternoon (i.e., no later than 3:00 pm) to feel recharged and avoid sleep inertia (i.e., feeling groggy and possibly experiencing insomnia). And please remember to take your nap in a dark room, laying down and free of any distractions or potential interruptions.   

To your health,

Dr. Sandoval
