We are a nation of chronically sleep-deprived adults. According to the U.S. Centers for Disease Control and Prevention, one out of every three Americans doesn't get enough sleep on a regular basis. This is not only affecting how we look and feel, it makes dealing with everyday stressors a challenge and if that wasn't tough enough, it's also killing our sex drive. When it comes to time management, sleep always seems like the first thing to go. Get up an hour earlier to hit the gym, stay late at the office and crawl into bed an hour or two later than we'd like. It all adds up. And to the guy who says, “I'll sleep when I'm dead,” I ask you this: Who wants to live if you're constantly overstressed and undersexed? Because here's why your love life dries up when you don't get enough sleep.
