How tired are you right now? If you're like many Americans, your answer probably leans more toward the sleep-deprived side.
Fifty to 70 million of us suffer from sleep problems, according to the National Sleep Foundation. And it's not just falling asleep that vexes us. The Center for Disease Control and Prevention found that one-third of the U.S population -- 100 million people -- aren’t staying asleep during the night.
“As a nation, we are not getting enough sleep,” says Dr. Wayne Giles, M.D., the standing director of the CDC’s Division of Population Health. To compound its importance, lack of sleep negatively affects overall health. A recent study found that individuals with insomnia are five times more likely to suffer from anxiety or depression and have double the risk of congestive heart failure.
