Carbohydrate-rich foods, such as pastas and breads, can make you more sleepy.
Carbohydrates work well with proteins to induce sleepiness, which makes combinations such as peanut butter on toast, cereal with milk, or cheese and crackers good bedtime snacks.
A large meal can make you more tired, especially one with a lot of carbohydrates.
Caffeine in foods and beverages is a stimulant that blocks hormones in the brain that make you feel sleepy.
While alcohol may help you relax and fall asleep in the short term, over the course of the night it inhibits the sleep process and can prevent you from getting deep, restful sleep.
