I agree.
But sleep experts say a lot of us really could use that nap. James B. Maas, the Cornell University sleep expert, says most people don't get enough sleep and that an afternoon nap can help. In fact, Maas coined the term "power nap" to emphasize that a nap can make a person more productive and energetic.
Many studies have shown that napping improves mood and performance.
This year, researchers at Flinders University in Adelaide, Australia, reported that they took test subjects who had had only five hours of sleep the night before and let them have naps of varying durations.
They found that even a 10-minute nap made the subjects feel less sleepy and more vigorous, and led to improved cognitive performance.
