Cheese and crackers
Old wives’ tales suggest that warm milk can make you sleepy, but it turns out there is actually science to back this up. Studies have found that many dairy products can help you sleep. Calcium, found in cheese, yogurt and milk, helps the brain use the tryptophan found in dairy to manufacture sleep-triggering melatonin. Calcium also helps regulate muscle movements, which means fewer sleep-busters like cramps or restless legs.

Lettuce
A salad with dinner could speed up your bedtime. Lettuce contains lactucarium, which has sedative properties, according to a study published in Food Science and Biotechnology. Romaine lettuce has the highest content of this compound, making it ideal for sleep. If you don’t feel like noshing on a head of lettuce, you can try this brew from the book Stealth Health: Simmer three to four large lettuce leaves in a cup of water for 15 minutes. Remove from heat, add two sprigs of mint, and sip just before you go to bed.

Pretzels
Foods like pretzels and corn chips have a high glycemic index. After eating them, you’ll have a natural spike in your blood sugar and insulin levels, shortening the time it takes you to fall asleep, according to a study published in the American Journal of Clinical Nutrition. Normally, you want steady levels to avoid mood swings and insulin resistance. (In those cases, reach for one of these 10 delicious low-glycemic snacks.) But if you are looking to get rest, the blood sugar and insulin increase helps tryptophan enter your brain to bring on sleep.
