If you skimp on sleep, your health pays the price. Sleep loss can ruin your memory and concentration; it can make you gain weight; and it definitely makes it harder to get out of bed early and hit the gym.
But even if you’re committed to logging the recommended 7 to 8 hours a night in bed, you might still find yourself tossing and turning when the lights go out. You’re not alone: Up to 1 in 3 adults say they occasionally experience insomnia, according to the American Academy of Sleep Medicine.
It’s no surprise that certain foods or drinks — think coffee, alcohol, and even too much sugar — can make your sleep woes worse. But you might not realize that others can actually help you snooze better.
Here are 8 foods and drinks for good sleep.
Food for Good Sleep: Walnuts
Walnuts contain melatonin, the hormone that makes you feel sleepy.
“Your body makes melatonin when it starts to get dark, but eating foods with melatonin could also help you feel more sedated,” says W. Christopher Winter, M.D., Men’s Health sleep advisor and author of the forthcoming book The Sleep Solution.
Try snacking on a handful an hour or two before bed, he says.
Not into walnuts? Sunflower seeds, tart cherries, and bananas are just a few of the many other foods that naturally contain melatonin.
Food for Good Sleep: Salmon
The pink fish is a top source of omega-3 fatty acids, which one Journal of Sleep Research study linked to deeper, more restful sleep. While the study was done on children, experts say that the findings probably hold true for adults, too.
Experts don’t fully understand why, but getting enough omega-3s could boost the sleep-promoting effects of melatonin.
Plenty of other seafood contains omega-3 fatty acids, such as herring, sardines, mackerel, oysters, seabass, shrimp, lobster, tuna, and cod. If fish just isn’t your thing, you can also find omega-3s in chia seeds, flax seeds, kidney beans, eggs, and chicken breast.
Food to Fall Asleep: White Rice
Research published in the American Journal of Clinical Nutrition suggests that eating 2 1/2 cups of white rice four hours before bed could help you fall asleep faster. Of course, that’s a lot of rice — but even eating a small amount of carbs could be helpful.
In part, it could be because your brain uses the carbs to make the neurotransmitter serotonin, which promotes feelings of calm and relaxation, Dr. Winter says.
Even though whole grains — like brown rice — are a healthier choice overall, it’s fine to switch to white rice every once in a while if you’ve been having trouble sleeping. Just go back to your usual fare once you start sleeping better, Dr. Winter says.
Food for Good Sleep: Eggs
They’re one of the few foods that naturally contain vitamin D, which emerging research suggests could have an impact on your sleep.
One recent study, published in Sleep, found that men who were deficient in vitamin D had more sleep disruptions and got less sleep overall compared to those who got enough of the vitamin.
The reasons why aren’t completely clear, but it could be that vitamin D targets neurons in parts of the brain that play a role in sleep. Shoot for 600 international units (IUs) per day, according to the Institute of Medicine.
If you don’t like eggs, other foods with vitamin D that might just help you sleep include wild-caught and canned fish, beef or calf liver, shitake mushrooms, and yogurt.
Drink for Good Sleep: Warm Milk
Milk contains calcium as well as the amino acid tryptophan, two things your brain needs in order to produce melatonin, Dr. Winter says. (Other sources of tryptophan include egg whites, pumpkin seeds, and everyone’s Thanksgiving favorite: turkey.)
Most milk is also fortified with vitamin D — so you’ll get that added bonus, too.
Warm it up, and its sleep-inducing effects might be even more potent.
“Consuming a warm beverage raises your body temperature,” says Dr. Winter. “So your body has to work to cool back down, and that cool-down can trigger sleepiness.”
Food for Good Sleep: Cashews
A quarter-cup serving of cashews delivers almost 20 percent of your daily magnesium, a mineral that plenty of people don’t get enough of.
That could spell problems at bedtime, since magnesium deficiency is linked to sleep disorders as well as restless leg syndrome, which often strikes at night and can make it difficult to fall asleep. Fall short, and the nerves in your muscles can actually fire off too many signals at once, which can cause cramping and leg restlessness.
“Magnesium plays a role in proper muscle contraction,” Dr. Winter says.
Other great sources of magnesium include swiss chards, almonds, spinach, and sesame seeds.
Food for Good Sleep: Sweet Potatoes
When it comes to sleep, the orange-fleshed vegetables pack a powerful punch.
A medium sweet potato contains 542 milligrams (mg) of potassium — around 10 percent of your daily recommended dose. Like magnesium, potassium promotes proper muscle contraction to keep nighttime leg cramps at bay, says Dr. Winter.
Sweet potatoes are also loaded with the carbs your brain needs to make sleep-inducing serotonin.

Drink for Good Sleep: Chamomile Tea
Chamomile contains compounds that studies suggest can ease anxiety and stress, upping the odds that you can actually fall asleep rather than spend the entire night tossing and turning.
Plus, like warm milk, a mug of hot chamomile tea before bed can promote feelings of sleepiness by causing your body temperature to rise and then drop.
Dr. Winter likes Republic of Tea’s Get Some Zzz’s tea, which contains chamomile along with other sleep-promoting herbs like passionflower and valerian.
