Sweet Dreams Are Made of This
How have you been sleeping lately? Ask that question of a growing number of sleep-deprived Americans, and you’re sure to receive some complicated or distressing answers. Research from the National Sleep Foundation shows that about 20 percent of us get less than six hours of sleep each night. For a small number of individuals, this amount of sleep is optimal. For the rest of us, going too far below the traditional eight hours per night can be anything from problematic to catastrophic.
Why aren’t people sleeping enough? Certain medical conditions, particularly those where pain is a predominant feature, can hamper sleep. So can sleep apnea, an illness thought to affect between 10 million and 18 million Americans, which is characterized by stoppages of breathing during sleep that can lead to repetitive sleep-wake cycles. People who work graveyard or rotating shifts, common in 24-hour cities like Las Vegas and Reno, often report that they get less sleep than they feel they need. And, of course, there’s stress, which can keep us from falling asleep and sleeping well once we do.
