Feeling tired? You're not alone. Forty-nine percent of Americans don't get the recommended eight hours of sleep a night.
The Centers for Disease Control and Prevention has declared insufficient sleep a public health epidemic. Lack of sleep can cause depression, weight gain, difficulty concentrating and a slew of physical and mental ailments. It can also end marriages. One of four married couples sleep in separate beds because of restlessness, snoring, body temperature and the eternal struggle over a shared blanket.
Despite the fact that we spend 33 percent of our lives sleeping, we invest very little in getting a good night's rest.
