How Did You Sleep Last Night?

Your sleep personality may reveal why you may not be getting enough sleep.

For most of her life, Carol Smith has never had much trouble with sleep. But all of that changed when she began working a 12-hour graveyard shift -- from 6 p.m. to 6 a.m. -- as a 911 dispatcher.

At times, she says she's had to struggle to stay awake and alert on the job. "It was very difficult for me," she recalls. "I'd get real fidgety, and doing any kind of paperwork was hard because it was so tough to concentrate. At times, I felt so uncomfortable that I just wanted to crawl out of my skin."

When You Have Trouble Waking Up

Brian Cyphers has always had trouble falling asleep at a "normal" hour. A few years ago, when the 24-year-old Chicagoan was dozing off between 3 and 5 in the morning and had to wake up at 6:30 to get to his job as a data entry clerk at a lab, he knew it was time to seek help. Cyphers sought assistance from Lisa Shives, MD, medical director of Northshore Sleep Medicine in Evanston, Ill., and a specialist in sleep disorders. Shives frequently sees patients who want to alter their night owl ways. "People...

But then Carol found relief. She participated in a sleep study at Henry Ford Medical Center in Detroit, and was diagnosed with "shift work sleep disorder" (SWSD), a condition that affects people whose sleep-wake and lifestyle demands are out of sync with their normal biological (circadian) rhythms. It consists of symptoms of insomnia or excessive sleepiness that occur as transient phenomena in relation to work schedules.

She now takes a prescription medication called Provigil (modafinil), which promotes wakefulness in people with debilitating excessive sleepiness associated with SWSD.

"I can breeze through my 12-hour shifts these days," Carol tells WebMD. "I only take the medication on the nights I work, and now I love working nights."

A Hard Day's Night

Sleep deprivation and related problems have become as American as caffeine-rich Starbucks coffee and 24-hour pharmacies. In the last 100 years, there has been about a 20% decline in total daily sleep time, says Gary Zammit, PhD, director of the Sleep Disorders Institute at St. Luke's-Roosevelt Hospital in New York City. The blame for that sleep deprivation rests with the fast-paced culture we live in, with more demands on everyone's time and the emergence of an around-the-clock, 24/7 society.

So whether it's your lifestyle or your personality traits, you may have joined the ranks of the bleary-eyed who are not getting all the shuteye their body needs. "Many people are staying up late surfing the net, or going to the supermarket at night because that's the only time they can get there," says Sonia Ancoli-Israel, PhD, professor of psychiatry at the University of California San Diego School of Medicine. "We've become so busy that something has to give, and for many people, it's sleep that they sacrifice."

In fact, sleep disruptions can provide clues to your health, both physical and psychological. These disruptions can help reveal whether you're burdened by stress or overwhelmed with high anxiety. Sleep disruptions also give hints on what medications you're taking, or whether you're experiencing chronic aches and pains. They can make you unproductive on the job, and moody and irritable at home, or as with Carol Smith before she found Provigil, they can be a sign that you're forcing yourself to stay awake when your internal body clock is desperately seeking slumber.

You say you are able to function well with fewer than seven hours of sleep. Some people say they can function on four to six hours of sleep each night, but research shows that adults who get fewer than seven hours of sleep — whether for just one night or over the course of days, weeks, or months — have more difficulty concentrating and more mood problems than people who sleep seven to nine hours.

Since you usually get too little sleep, please talk to your doctor about your sleep patterns. Poor quality sleep can affect many areas of your life and health, and your doctor may be able to help you if you have insomnia or other conditions affecting your sleep.

Sleep deprivation can have both short- and long-term consequences. Learn more about the health consequences of sleep loss. If you're concerned about having trouble falling asleep or staying asleep, assess your risk for a sleep disorder.
