Something we ardently love, but—thanks to work, family, and a social life—we never seem to get enough of.

Health.com filled us in on some of the other surprising benefits to snoozing, including a better memory, reduced inflammation, sharper focus, increased creativity, lower stress, and even overall happiness.
