From early birds to night owls, we all can
agree that when we finally lay our heads on the pillow we’d like to actually go
to sleep, thank you.
Nothing is more annoying than insomnia, and
the evidence is piling up that sleep is essential for good health. Although the
research is a bit spotty when it comes to which foods help or harm sleep,
anecdotal evidence does suggest that certain items consumed right before
bedtime are more likely to be “sleep promoters” while others may be “sleep
stealers,” says Russell Rosenberg, Ph.D., CEO of the National Sleep
Foundation. Here’s a list of potential good guys and bad
guys when it comes to getting some shut-eye.
Worst: Chicken
Chicken or any type of protein is going to be
counterproductive if consumed at night. “Digestion is supposed to slow by about
50% while you’re sleeping but if you eat a lot of protein, you digest [even]
more slowly,” explains Rosenberg. Instead of focusing on sleeping, your body is
focusing on digesting. Adding a carbohydrate to the protein can tip the balance
back towards sleep.
Best: Cherries
Cherries are one of the few natural foods to
contain melatonin, the chemical that helps control our body’s internal clock,
says Keri Gans, a registered dietician in New York City and author of The Small
Change Diet. One study—albeit a small one—found that drinking tart cherry
juice resulted in small improvements in sleep duration and quality in adults
who suffered from chronic insomnia. (And travelers often take melatonin
capsules to combat jet lag). Why not a few cherries, tart or otherwise, to
promote sleep?
Worst: Wine
Alcohol of
any kind is “terrible” for sleep, says Rosenberg. Why? It metabolizes quickly
in your system and causes you to wake up multiple times during the night. One
study found that a glass of bourbon or vodka mixed with caffeine-free soda at
bedtime increased the amount of time women spent awake during the night by 15
minutes. It also reduced nightly sleep time by 19 minutes and diminished
quality of sleep. If you don’t refrain from alcohol for our own benefit,
do it for your mate. “Alcohol makes snoring worse so it will impact you and
your potential bed partner,” said Rosenberg.
Best: Milk
You may have fond memories of your mother or
grandmother making you a glass of warm milk to help you fall asleep. This may
not be just an old wives’ tale. Milk contains the amino acid tryptophan, a
precursor to the brain chemical serotonin. Although the topic is a
controversial one, some people believe that tryptophan and serotonin might make
it easier to sleep. Or maybe a simple glass of milk brings back soothing
childhood memories, which help you drift off.
Worst: Dark Chocolate
Chocolate contains not only calories, but
caffeine, especially dark chocolate. A 1.55-ounce Hershey’s milk chocolate
bar, for instance, contains about 12 milligrams of caffeine, or the same amount
as three cups of decaffeinated coffee. A Hershey’s special-dark bar has 20
milligrams of caffeine, about the same as half an ounce of espresso. Chocolate
also contains theobromine, another stimulant that can increase heart rate and
sleeplessness.
Best: Jasmine Rice
Jasmine rice ranks high on the glycemic index,
meaning the body digests it slowly, releasing glucose gradually into the
bloodstream. A 2007 study in the American Journal of Clinical Nutrition
found that consuming jasmine rice four hours before bedtime cut the amount of
time it took to fall asleep in half when compared with eating a
high-glycemic-index meal at the same time interval. The authors speculate
that high-glycemic-index meals may up the production of tryptophan.
Worst: Indian Curry
It’s not Indian food per se but the heavy
spices, which can keep you awake at night. One study conducted in
Australia found that young men who poured Tabasco sauce and mustard on their
dinner had more trouble falling asleep and experienced less deep sleep than men
who ate blander suppers. Spices can also cause heartburn. So definitely
don’t do spicy and high-fat in the same late-day meal. It’s a potential
sleep-wrecking recipe.
Best: Fortified Cereal
Carbs in general are good for sleep but it’s
not a great idea to binge on a box of cookies before bedtime (or
anytime). Instead, try a bowl of Kashi or shredded wheat which contain
“good” or complex carbs. Even better, cereal goes well with milk, which has its
own sleep-promoting qualities. “That’s two for the price of one,” Rosenberg
says. Other complex carbs are quinoa, barley, and buckwheat.
Worst: Red Bull
Yup, the culprit here again is caffeine, and
it’s present in spades. An eight-ounce Red Bull energy drink contains about 80
milligrams of caffeine or equivalent to a one-ounce Starbucks espresso. Five-Hour
Energy packs 200 milligrams of caffeine into just two ounces, which means you might
as well be imbibing 16 ounces of regular coffee. With this much caffeine,
you might do well to avoid energy drinks even earlier in the day. “In some
people caffeine can take up to eight hours to wear off,” says Gans.
Best: Bananas
Bananas help promote sleep because they
contain the natural muscle-relaxants magnesium and potassium, says Gans.
They’re also carbs, which will help make you sleepy as well. In fact,
bananas are a win-win situation in general. “They’re overall health promoters,”
says Rosenberg. “We need potassium for cardiovascular health and cognitive
functioning.”
Worst: Mountain Dew
Mountain Dew MDX along with jolt Cola and
Vault contain 71 milligrams of caffeine per 12-ounce serving. That’s the upper
limit of what the U.S. Food and Drug Administration allows. Other sodas
aren’t much better. Also, typical soda drinks like Pepsi and Coke contain
citrus as well as sodium benzoate and other chemicals which can aggravate the
gastrointestinal tract and promote acid reflux, not a recipe for a good night’s
sleep.
Best: Turkey
Like milk, turkey contains tryptophan, a
chemical that can make people doze off in front of the TV after Thanksgiving
dinner. But if you’re a die-hard insomniac, a meal’s worth of turkey (or a
glass of milk) isn’t likely to help you. “You’d have to drink a lot of
milk or turkey to have a major effect,” says Rosenberg. “[But] if you need a
little bit of a push in the right direction [it might help].”
Worst: Coffee
Coffee contains caffeine, which is a central
nervous stimulant. Translation: Drinking Java too close to bedtime will keep
you up at night. Of course, people differ in their sensitivity to caffeine
and that’s usually based on how much caffeine you’re accustomed to consuming,
says Timothy Roehrs, Ph.D., a senior scientist with Henry Ford Sleep Disorder
and Research Center in Detroit. If you don’t know your tolerance, skip the
java, especially late in the day.
Best: Sweet Potato
Sweet potatoes are a sleeper’s dream. Not only
do they provide sleep-promoting complex carbohydrates, they also contain that
muscle-relaxant potassium. Other good sources of potassium include regular
potatoes (baked and keep the skin on), lima beans, and papaya.
Worst: Bacon Cheeseburger
The stratospheric fat content of this
particular fast food is guaranteed to be a sleep killer. Fat stimulates
the production of acid in the stomach, which can spill up into your esophagus,
causing heartburn. Fatty foods can also loosen the lower esophageal sphincter,
the barrier between the stomach and the esophagus, making it even easier for
acid to get in all the wrong places. In fact, there’s almost nothing to
recommend this kind of high-fat, salt-laden indulgence if you want to preserve
your health, including the quality of your sleep.
Best: Valerian Tea
The root of the valerian plant has been shown
in some studies to speed the onset of sleep and improve sleep quality. Some
people hold that valerian tea along with motherwort, chamomile, and catnip
brews, none of which contain caffeine, will help make you drowsy. It may not be
any property of the actual tea however, but the power of the relaxing ritual as
you get ready for bed, says Roehrs.
