Remember when you were younger, and you can’t fall asleep – no matter how many sheep you count – your mother would give you a glass of milk and you’d feel your eyelids becoming heavy … did the warm milk really have something to do with you feeling sleepy?
In a word, yes – BUT that’s not the only reason why you fell asleep. Milk contains tryptophan, an amino acid that helps induce sleep. However, milk alone is not responsible for you falling asleep when you were younger. Back in the day, electronics such as televisions, computers, smart phones and tablets were non-existent – as such you weren’t distracted by them; furthermore, you probably had a fun time running around while at play – this form of exercise would have helped make you feel sleepy. In addition, as a young child, you probably weren’t allowed to drink any caffeine.
So it’s not just milk but a combination of a lot of things. Milk probably just helped relax your muscles.
