According to " Why do we need to sleep?", Tom Stafford reports that one living activity is important as breathing or eating is sleep because it helps us to improve our memories by reorganizing, refreshing, and saving energy, especially a day time nap.

This article remind me when I was in university because I always spent ten minutes after lunch for taking a nap. While napping, I felt like I slept for long hours. Of course, this habit was appeared while I was working. But, not today.
