42. Warm Milk
Countless TV shows and movies have had the trope of the mom serving up a warm cup of milk to help her young one go to sleep. Though some people might be skeptical about the veracity of the stereotype, science actually does support the claim! Milk’s sleep-promoting properties might be due to the amino acid, tryptophan. Warm milk before bed can help you fall asleep more easily, though the evidence on whether or not it prevents waking throughout the night is still uncertain.
