In Today's World, the Well-Rested Lose Respect

A Good Night's Sleep

Believe it or not, some of us need to be taught how to sleep. Too engaged in work or play, we put off going to bed. Or we wake up in the middle of the night, mind racing, unable to drift off again. Soon enough, we're caught in a vicious cycle where one rotten, sleepless night follows another. So we reach for a pill.

  

Not so fast, says Dr. Helene Emsellem. To live up to our true sleep potential — and all of the health benefits that come from a good night's rest — the sleep-troubled need to change their nighttime habits.

  

Emsellem, a neurologist and medical director of the Center for Sleep and Wake Disorders in Chevy Chase, Md., is a nationally known sleep expert and author of the book Snooze... or Lose! Here, she answers your questions on sleep.

Almost everyone has heard a story about someone famous who doesn't need much sleep: Martha Stewart, Bill Clinton, Condoleezza Rice, Margaret Thatcher, the list goes on and on.

In our fast-paced, global society, many people consider it a big plus to need as little sleep as possible. But almost every sleep researcher will tell you that most people need at least seven hours of sleep for biological and psychological health. So there is a glaring disconnect between what the messages in our culture say about sleep and the messages we receive from scientists.

The Sleepless Badge of Honor

Think of the scene in the film Thank You for Smoking. Nick, a public relations guy for the smoking industry, is talking to a Hollywood mogul, who calls him up late at night to give him an update on a deal.

"Are you still at the office?" Nick asks.

"Do you know what time it is in Tokyo?" replies Jeff, the mogul, "4 p.m. tomorrow. It's the future!"

"When do you sleep?" Nick asks.

"Sunday," says Jeff, in a priceless moment.

The scene in the film encapsulates this myth that successful people don't need sleep and even provides a rationale: that our fast-paced society no longer lets us have such luxuries.

Dr. Eve Van Cauter, a sleep researcher and professor of medicine at the University of Chicago, says that many people today, especially in the United States, take pride in not getting much sleep.

"Sleeping as little as possible is viewed as a badge of honor here," Cauter says.

Short sleepers, people who can do with five hours of sleep a night, do exist. But most sleep researchers say they comprise only 10 percent or less of the population.

Dr. David Dinges, a sleep researcher at the University of Pennsylvania, questions whether they are "as prevalent as is claimed in society" and whether they are really so special.

Dinges also believes that many people who say they are short sleepers are getting more sleep than they are willing to admit. For example, they sleep on the way to the airport in the limo.

Dinges says people often don't count dozing off as sleep if they are not in their pajamas or in bed. He also notes that many people who fall asleep in meetings or consume large amounts of coffee consider that normal these days and not a sign of being sleep-deprived.

Van Cauter notes that every time she takes a morning flight, one-third of the plane is fast asleep within minutes of the plane taking off.

I live and report in New York City, and there is definitely a kind of pride or resignation here about lack of sleep. I started listening to people talking about sleep habits in the coffee shop where I get my morning coffee.

"Sleeping more than five hours feels like a waste of time. You could be reading or on eBay," Evangeline Morphos, a Columbia University professor, told me.

Attorney Carolyn Schrager's high-school-age daughter told her the one thing she wishes she could change about her life is to do away with the need for sleep.

Less Sleep Than Ever

Although it is hard to get real statistics about how much people slept in different periods of history, there are some pretty good indications that even five decades ago, people slept much longer on average.

Van Cauter notes that the National Cancer Society surveyed more than a million Americans in 1960 and found that people said they got an average of eight-and-a-half hours of sleep.

This was, of course, in a time period when television stations went off the air by midnight, and there were few late-night diversions, like online shopping.

Van Cauter says most surveys today put the average sleep time of Americans at six or seven hours.

"The data is limited, but they strongly suggest that over the past four or five decades, sleep duration has decreased by one and a half to two hours," she says.

Sleep Disconnect

And Van Cauter even wonders about all those famous people who supposedly don't need sleep. She notes that Bill Clinton, a notorious short sleeper, had heart surgery in his 50s, with no obvious risk factors.

Dinges says most people will show serious impairments if they are deprived of sleep for even a few days. The problem is most people assume they are fine when they are not.

"People will often say, 'I am good to go,'" he says. "It is that disconnect between your ability to introspect your alertness and impairment and how impaired you are cognitively, which is why we think many people believe they are doing fine when they not doing so fine."

Cliff Sloan, the publisher of Slate magazine, says he needs only five hours of sleep. He gets up early in the morning, and regards the early morning hours as a special time when the world is peaceful.

He notes that his wife is the complete opposite. She gets eight hours of sleep, would love 10, and "is someone who loves sleep and thinks it is absolutely insane that I am not indulging in one of life's greatest pleasures."

Sloan notes that both he and his wife are extremely productive. These are just differences of temperament and physiology, so it's ridiculous to claim that there is a link between success and lack of sleep, he says.

Sloan may be one of those unusual people who don't need so much sleep, although Dinges says, "I always say to these people, come to my lab and find out for real."

And Van Cauter makes a very unusual argument. She says that the amount of sleep you need also depends on what type of work you do. Celebrities, politicians, leaders of various kinds may actually need less sleep than others because the work they do involves constantly shifting their focus and attention. They might talk to a person about one thing, and then go on to another group, and then move to a new location.

"If, on the other hand, you have to get on the road and drive on a flat highway for four hours," sleep might well overwhelm the same person, she says.

Trendy Today, Dangerous Tomorrow?

Van Cauter believes we are in a period now very similar to where we were with smoking 20 years ago. She envisions a time 20 years from now, when knowledge, research and even litigation (perhaps lawsuits against sleep-deprived drivers who cause accidents) will combine to change public perception so that lack of sleep is finally seen as dangerous, not something to be proud of.

But Dinges says changing public perception may not be so easy since there is something built into our brains that makes us want to do more and more in less and less time.

"We are the ones that came up with artificial light and skyscrapers and going to the moon," he says, not the birds or crocodiles.

There is something very attractive to human beings about wanting to do with less sleep, no matter how much sleep restores us, helps our immune system or allows us to be more emotionally stable.

Emsellem, a neurologist and medical director of the Center for Sleep and Wake Disorders in Chevy Chase, Md., is a nationally known sleep expert and author of the book Snooze... or Lose! Here, she answers your questions on sleep.

NPR: By far, the most common complaint from our listeners: They wake up about four hours into their night's sleep, and then can't get back to sleep for an hour or two, if at all. Why does this happen, and what's your advice?

Waking up in the middle of the night is one of many forms of insomnia. These mid-sleep awakenings often occur during periods of stress — physical or emotional — and depression could be a factor. I suggest first trying some general stress-reduction strategies. Make sure to get some exercise into your day, and then set up a quiet, relaxing bedtime routine, such as a warm shower or bath, soft music and quality time with a bed partner, if possible. Gentle upper-body stretches or gentle yoga to unwind tight muscles before sleep may be helpful, too.

When you wake up in the middle of the night, staying in bed and listening to some music or a book on tape with the lights out may help with the transition back to sleep. If the problem persists, it may require a visit to your doctor and medication. The typical hypnotic drugs used at the start of your night's sleep are not particularly helpful for this type of problem. Low doses of medications in the antidepressant and anticonvulsant classes may be helpful — even when there is no clear-cut depression.

You mentioned using melatonin in small doses as an aid to sleep. How do we figure out the right dosage? — Jessie Norris, Urbana Ill.

There are many over-the-counter brands. Melatonin is considered a dietary supplement, rather than a drug, which means the FDA doesn't tightly regulate it, in terms of safety and efficacy. But groups such as ConsumerLab.com and the NSF (National Sanitation Foundation) evaluate products to make sure that the product at least contains what the label says it does. Look for the NSF stamp on the bottle of whatever brand you buy.

I have found, in my practice, that between 200 and 500 micrograms of melatonin — a very small dose — seems to be effective; higher doses may cause sedation. In normal individuals, the body begins to produce its own melatonin six to eight hours before bedtime. In night owls, melatonin secretion begins very late. In order to help get your body ready for sleep earlier, you can try taking a low dose of melatonin six to eight hours before the desired bedtime. Melatonin on its own may not work very well; it works best in combination with behavioral reinforcement, such as sticking to a regular wake-up time and exposure to bright light in the morning.

At what age is it safe to give a child melatonin as a sleep aid? — Bruce Sturgeon, Seattle, Wash.

There aren't any big studies on melatonin use in children, and there is not a great deal of literature about the use of melatonin in teenagers. Melatonin is a dietary supplement that is not tightly regulated by the FDA. If you plan to use melatonin for your teen, check with the family physician before doing so. Side effects have been rarely reported, and readers can go to pdrhealth.com for a full listing of reported side effects. If side effects occur, it's usually with high doses, or when melatonin is used in combination with other prescription drugs.

There are concerns about the increasing frequency of the use of prescription hypnotic drugs for sleep problems in teens and children. I believe it's very important to look at the underlying sleep schedule issues first, and to try to treat those problems before resorting to prescriptions.

I am a firefighter and a father. My sleep schedule is almost never the same, always interrupted in the middle of the night, often several times throughout the night, and usually not at the same time. I obviously am unable to change this pattern, so what can I do to mitigate the negative effects of this as much as possible? — Kenny Stuart, Seattle

As difficult as it sounds, try to maintain some kind of regular sleep. Try to go to bed at the same time — even if you know you have to wake up in just a few hours. A planned nap at the same time in the afternoon on your off days may be helpful. Too much sleep in the afternoon will make it hard to fall asleep at the usual bedtime, so a maximum 90-minute nap before 3 p.m. may be best. And when it's time for you to go back to sleep after an interruption, listening to music or a book on tape may help you wind down and fall back to sleep as soon as possible.

I just keep doing things at night rather than go to bed. I don't wind down and go to bed, even though I pass the logical hour that would assure I get adequate sleep. I feel tired the next day and wish I had gotten more sleep. Why is there a disconnect for some people? The night owl doesn't recognize there is a morning to deal with. — Tara Lawrence, Los Gatos, Calif.

I am not sure why we are so uncoachable at night! Most night owls love the quiet, uninterrupted solitude. Some have obsessive qualities and just can't let go. And I think most of us just have too much to do in the daylight hours, and it spills over into our nights. The challenge is to set a schedule for yourself with a reward system (you get to decide what your own reward is!) that will make you want to let go and go to sleep. It's common for someone going to sleep, on average, at 2 a.m., to make a resolution to go to bed at 11 p.m. The switch is just too dramatic and we can't adapt, so you get into bed and get aggravated that you can't fall asleep. I would suggest that you try to adjust your schedule back in 20-minute increments — and remember to adjust your wake-up time earlier by the same amount. Once you can consistently fall asleep 20 minutes earlier — usually after a few days — it's time to take on another 20-minute challenge.

I just had a baby, so my sleep schedule has been turned upside down. Now my baby is sleeping much better, usually all through the night, but I can't seem to sleep well at all. Often I will lie awake nearly the whole night through. Any suggestions? — Nicole Anderson, Seattle

First, take a careful look at your mood and consider discussing the problem with your doctor. A postpartum depression may manifest itself with sleeplessness and is a serious problem needing medical attention. If your mood is fine and you just can't sleep, then keep a sleep log for a week, so you can see when you are actually falling asleep. You can download an easy-to-use log at www.snoozeorlose.com. Take a look at the time that you are actually falling asleep. Usually this type of problem is best managed by actually restricting the time in bed to just the times that you are actually sleeping and then gradually going to sleep earlier (see the question above). A good wind-down routine in the evening, which separates your busy day from bedtime, is imperative, along with exercise earlier in the day.

I have an 11-year-old daughter who refuses to sleep in her own bed. I may get her to start there, but by the morning, she's inevitably on the living room couch. I've done everything I can to make her bed and her room inviting and comfortable. What do you suggest? — Ellen Myrick, Nashville, Tenn.

If your child is going down to the couch, you have to find out what's disturbing about their room. Is it too dark, too quiet, too messy, too hot or too cold? Or, are they watching TV in the living room? You have to be a little bit of a detective, and you have to talk to them during the day about what's going on — at night is not the time to start the discussion. And making the room inviting and comfortable is important, but their idea of comfortable may not be the same as yours.

A child who is afraid of being in their own room always raises the question: What are they afraid of? Exploring this can be difficult, and if the problem can't be resolved, letting the child talk one-on-one with the family doctor or pediatrician would be appropriate.

NPR: Are there any studies showing a link between high schools opening later and better student performance?

Just about every school district that has done a study and changed its start time has shown a trend toward improvement in grades. But the dramatic change has been an improvement in the graduation rate. These schools are retaining and graduating more students. In one study, in the Edina school district in Minnesota, it's very impressive how many more students graduated after the school start time changed. A study in the Arlington, Va., school district also reported a dramatic improvement in the feeling of well-being among students and teachers.

The upshot is that kids actually sleep during the extra time, they're not wasting it.

I have a college son in his last semester of his senior year. His body clock is reversed, up until 4 or 5 in the morning, sleeping until noon. He is unsuccessfully trying to straighten out his routine. What is your best advise to help him fall asleep while he is in this transition phase? — Kathy Taylor, Duncanville, Texas

It's important to remember that it is the wake-up time in the morning that governs the schedule. As long as he sleeps until noon, he won't get sleepy until 4 a.m. So I would suggest waking up a half hour earlier every two or three days. Another critical point is that if he adjusts his wake-up time for a job this summer on the weekdays, and still sleeps in until noon on the weekend, he's still going to be half in and half out of both of those schedules. Monday and Tuesday mornings will not be pleasant for him.

This is not so much about sleeping, it's about waking up. No matter how much sleep I get, the first couple of hours after waking, I bumble and stumble around. I'm not a coffee drinker, so I don't think it's the need for caffeine. Any advice about waking up bright and alert? — Monta Gardner San Diego

I would keep a sleep log for a week or two, and if you are consistently getting eight or nine hours of sleep and you're still waking up tired, it's time to go see the doctor. There may be a metabolic problem, like an issue with your thyroid. You may be anemic. Or there may be a sleep disorder, such as sleep apnea (which, in women, can occur without snoring) or even narcolepsy.

NPR: What's your opinion on devices that help people "ease" out of sleep, from dawn simulators to alarm clocks that supposedly pick the best time in your sleep cycle to wake you up?

If they feel good and you get up on time, use them. If they don't wake you up on time, don't use them. The bottom line is, if you've gotten enough sleep, you should awaken spontaneously before your alarm.

I am addicted to the snooze button. Sometimes I will hit it for 90 minutes. Do you have any advice? — Seth Callahan, San Francisco, Calif.

Yes. Don't disturb your last 90 minutes of sleep with a snooze button. Set your alarm for the time you really need to get up and then get up and go. You obviously need the sleep.

How do you know if you have sleep apnea? Are there signs? (Other than being overweight, snoring, and being especially sluggish in the morning.) — JP LaFond, London, U.K.

There are other risk factors, such as having a small chin and jaw structure or a short, big neck or a long, skinny neck. But beyond these things, if you're waking up tired in the morning without any obvious explanation, then sleep apnea (when you repeatedly stop breathing in your sleep for periods of 10 seconds or longer) may be present. An overnight evaluation in a sleep laboratory is the best way to make a diagnosis. We now know there are major long-term health consequences to leaving apnea untreated. It's very important, if the question arises, to follow through and sort it out.

Last week I woke up in the shower. This is obviously not the ideal way to catch those Zs. I'm a 19-year-old male, and I've been losing sleep my entire life over sleep talking and sleepwalking. I would love to know how to ease this problem, and sleep more soundly at night. — Patrick Smith, Columbia, Mo.

Generally, sleepwalking behaviors occur occasionally and don't put people at risk, nor do they take up a significant amount of sleep time. If you find that your sleepwalking is putting you into potentially dangerous situations — you find yourself outside, in the shower, or near open windows — and if it's occurring more than several times a year, than it may be safest to seek treatment. If your family practitioner doesn't know how to manage it, see a sleep doctor. Sleepwalking can also be a side effect of some medications, in which case you should also talk with your doctor.

If I stop moving after 7-7:30 in the evenings, I fall asleep within minutes (i.e. watching TV, reading a story to my children, reading a book, etc.) I am 30 years old and have experienced this since I was a teen. Is this a sleep problem? How do I get more energy in the evenings? — Chris Rauch, Bourne, Mass.

Yes, if you are getting seven to nine hours of sleep on a regular basis at night, and you are sleepy during the day, you may have a sleep disorder. If you get up at 5 in the morning, then it makes sense if you're ready for sleep by 9 p.m. To sort out whether there is a problem, keep a sleep log to see how much sleep you're getting on a regular basis and that you're getting to sleep at a regular time. If your sleep schedule is consistent, then there may be an underlying sleep disorder and you should see your doctor.

I am a 55-year-old female, nearing menopause. For more than two years now, as I drift off to sleep I experience hypnic jerks. They keep me awake. Most nights, I need a small dose of drugs to get beyond these tiny, repetitive, shock-like fireworks in various parts of my body. I have been to many doctors and a neurologist. No real answers. Does this come with the "menopause" territory? Will I ever be able to just drift off to sleep again? — Jane Steckling, Gustine, Calif.

Yes, I hope you will! Hypnic jerks are normal responses as we transition into sleep. Typically, the average person may feel one or two, but in some individuals these may be exaggerated and may interfere with falling sleep. I personally have not seen a dramatic increase in these with menopause vs. other conditions. Sometimes these have an underlying metabolic factor, and it may be worth it to try a banana at bedtime to insure that you are not potassium depleted. A warm shower and gentle stretching exercises — especially for the calves and neck and shoulder muscles — just prior to bed have helped some of our patients. For others, medication may be the only solution.

How can I go about finding a good "sleep doctor" in my area? — Andrea Davis, Glendale, Calif.

The first resource is your primary care doctor. Generally, your own doctor can refer you to a physician they know and trust. And often it's a good idea to talk to your family doctor anyway. A general practitioner has a drill for a tired patient — a good physical exam, lab work checking the thyroid, Lyme disease, anemia — and that's an important first step. You can also check the American Academy of Sleep Medicine's Web site. It has a directory and can give people a listing of sleep doctors in their areas.
