Catching some Zs. Getting 40 Winks. Slipping into the Arms of Morphius.
We have many expressions for getting some sleep, but our knowledge about what we get from sleep was fairly limited, until recently.
Now we have a better idea what benefits sleep gives to us; physically, mentally, and even creatively. The knowledge comes from places like the sleep lab at the University of California-Berkeley, run by Matthew Walker.
He is the author of a new book, Why We Sleep: Unlocking the Power of Sleep and Dreams.
