Drinking a glass of warm milk will help you fall asleep. The Truth: The theory is this: milk contains tryptophan (the amino acid best known for being in turkey), which when released into the brain produces serotonin—a serenity-boosting neurotransmitter. But when milk was tested, it failed to affect sleep patterns.
So it's psychological that we think it helps us fall asleep when it actually doesn't..
