Eat Yourself Drowsy
Want to fall asleep faster? Have some lettuce. According to a 2017 study, lettuce—especially romaine—contains lactucarium, which has sedative properties and affects the brain similarly to the way opium does. Antioxidants in lettuce and other vegetables may also help, by counteracting the oxidative stress caused by sleep disorders.
You can kick it up a notch by topping your lettuce with fish such as tuna, halibut, or salmon, all of which are high in vitamin B6. Your body needs B6 to make serotonin, a relaxing neurotransmitter, and melatonin, a sleep-regulating hormone. Cherries, bananas, pineapples, oranges, and walnuts also naturally boost levels of melatonin, while kiwifruits contain serotonin.
