It’s Time To Get Some Sleep

The more we do, the less we sleep: That is making us sick

If getting a good night’s sleep seems like an impossible dream, take solace in the fact that you’re one of 70 million Americans suffering from a sleep disorder, according to the U.S. National Institutes of Health.

The problems range from insomnia caused by emotional stress or depression, to an inability to get to sleep – also known as delayed sleep syndrome – to restless leg syndrome, involuntary muscle movement that keeps folks from getting a full rest.

Whatever the cause, lack of shut-eye costs the country $16 billion in health-care expenses and $50 billion in lost productivity, the agency estimates. And the situation doesn’t seem to be improving. More Americans are meeting the demands and stresses of daily life by getting less sleep, not more, even though studies show that skipping sleep hinders productivity, slows down reaction time and decreases the ability to focus.

So how much sleep is enough? Adults need between six to eight hours of sleep a night. And nighttime really is the best time for sleep, since our body clock revs us up during the day and winds us down after dark.

When your inability to fall or stay asleep begins to interfere with work or other responsibilities, it’s best to see a doctor. Still, there are steps you can take to ensure you drift off to dreamland when your head hits the pillow.

“I like my patients to work on habits first,” says Dr. Hitesh Makkar, a pulmonary specialist in Akron, Ohio, who also specializes in treating sleep disorders.

He notes the trick to curing those sleepless nights is to work on the underlying cause and to practice good sleep hygiene. Here are some suggestions:

Stick with a schedule

Go to bed at a regular time and get up at a regular time. Having a schedule seems to strengthen the circadian cycle, the body clock that regulates our sleeping and awakening.

Rise and shine

Work out early in the day, not late in the evening. The body clock prepares us for sleep by slowing lowering our body temperatures. Exercise raises the body’s temperature. If a trip to the gym is part of your routine, do so at least four hours before bedtime.

Cut the caffeine

Sipping a venti mocha latte at 6 p.m. almost guarantees you’ll be tossing and turning at midnight. That’s because the half-life of this stimulant – the time the body needs to metabolize half the amount of caffeine consumed – is about six hours. To compensate for a restless night, you’ll probably reach for another cup of coffee, starting the cycle again.

Try a bedtime snack

A cup of warm milk seems to help induce sleepiness, although the science behind the claim is debatable. The sleep-inducing amino acid tryptophan, found in milk and other foods such as turkey, cheese, peanuts and tuna, induces sleep when it enters the brain. The protein in milk may decrease the effect of the tryptophan, though.

No late-night alcohol

Don’t down a glass of beer or wine before bedtime, though. These drinks make you sleepy but don’t produce the deep, restorative rest, warns Dr. Nancy Foldvary-Schaefer, director of the Sleep Disorder Center at Cleveland Clinic, Cleveland.

“Alcohol markedly fragments the quality of sleep,” she says.

don’t fight Still can’t sleep? Give in. If you lie in bed longer than 20 minutes without falling asleep, don’t toss or turn.

“If you can’t go asleep, don’t stay there. Get up until you’re tired and then try again,” Makkar says. Keep your activities relaxing, though. Don’t watch action movies or read a mystery novel. Avoid over-stimulation that might further delay sleep.

Clocking It

How your body’s internal controls manage your sleep cycle


“Continuously, our body made adjustments to keep us in tune with society. The most important factor is our ability to adjust to light. Light is the most important stimulus by which we can adjust the internal clock,” — Dr. Kumar Budur, a sleep specialist a Image courtesy iStock Photo

If you’ve ever caught your head dropping around 1 or 2 p.m., don’t blame yourself. Blame your body – specifically, the biological cycles that scientists call the circadian rhythms.

Most people know the rhythms rule everything from the most natural times for sleep – between midnight and 7 a.m., and again from 1 to 4 p.m. – to blood pressure, hormone levels and heart activity.

“Circadian rhythms are the cyclical changes that occur regularly every 24-hours,” explains Dr. Kumar Budur, a sleep specialist and psychiatrist at Cleveland Clinic in Cleveland. “The rhythms respond to light and dark, and help keep humans in touch with society.

But did you know your body has a master timekeeper?

Researchers have found that all cells have an internal clock that governs daily rhythms. In humans, each organ has its unique cycle. This master time-keeper is a small group of cells called the suprachiasmatic nucleus located in the hypothalamus. These cells respond to light and the absence of it and help the body keep up with the demands of society.

Budur explains that the body’s natural “day” is 24 hours and 18 minutes. “Continuously, our body made adjustments to keep us in tune with society. The most important factor is our ability to adjust to light. Light is the most important stimulus by which we can adjust the internal clock,” he says.

You feel more alert in the summer because you are more alert. Longer days mean the body doesn’t get the signal to sleep until later in the evening. And, if you find yourself winding down around 9 or 10 p.m., it’s because lack of light tells the SCM to prepare the body for rest.

But work and family obligations may put us out of sync with our internal clocks. The consequences can range from a shortened attention span to problems falling or staying asleep. Long-term consequences can include depression or substance abuse.

Night-shift or swing-shift workers, who are often at odds with the body’s clock, are especially vulnerable to some of these problems. That’s because they need to stay awake when the physiological changes are shutting the body down. And when they want to rest, the body is generating impulses to keep them awake, Budur says.

Folks who find themselves traveling across numerous time zones are also susceptible to sleep disorders.

“Usually humans can make minor adjustments up to three time zones,” Budur says. “If it’s more than three time zones, then it’s hard for body to make adjustments. That’s when we get into problem with jet lag, difficulty falling asleep, or staying asleep, excessive daytime sleepiness.”

Following these tips for good sleep hygiene will help you sleep when your circadian cycles have gotten out of sync from work, stress or jet lag:

Turn down the lights

If you work nights, you can get a good day’s rest by darkening the bedroom. If it’s not possible to darken a room, invest in eye masks or ear plugs. The goal is to mimic nighttime and trick the body into lowering its temperature and otherwise preparing for sleep.

Travelers, reset your clocks

Reset your internal clock by shifting your exposure to light. Online jet-lag calculators, such as the one featured on www.bodyclock.com, provide instructions on readjusting your internal clock.

Of course, if sleeplessness or other problems are affecting your work or relationships, then seek professional help.
