For many people, a short power nap helps them make it through a busy and long day. Taking a power nap may be more worthwhile than you can even imagine. The key is to keep the nap short, because if your nap is long you may end up groggier than before the nap. Having the right mind set to take a nap is important, so it is best to take the power nap in the morning or soon after lunch and stay away from foods with too much caffeine, fat and sugar. Try to find a quiet place, and set an alarm. Chances are you will be more productive after the power nap.
