Strange, true thing that might convince you (as if you need it): When you lose sleep, you also risk losing your sense of humor. No joke: The ability to "get" that something is funny requires you to process information cognitively as well as emotionally—and
that processing is severely affected by a lack of sleep, explains William D.S. Killgore, an associate professor of psychology at Harvard Medical School. In one of his studies, sleep-deprived participants had
significant difficulty recognizing when items like news headlines and cartoons were supposed to make them laugh.
