On the other hand, lots of research shows that naps are good for people. They are suppose to refresh you and give you extra energy in the second part of the day. Regular nappers are smarter, quicker, and more alert. All I can say to this is that perhaps we are just not all the same.
So if naps make you feel better, go ahead and take them, but if you are like me, don't feel guilty about getting all of your sleep at night even if you sometimes get tired during the day.
