"A Glass of Warm Milk will Help You Snooze"
Even thousands of years ago, the Talmud associated drinking milk with sleep. Today there's no scientific evidence that it has the slightest impact on drowsiness. Milk does contain the nap-inducing amino acid tryptophan, but only in trace amounts. Eggs and cheese have more, but even an egg and cheese sandwich won't knock you out. (You'd probably have to eat seven of them, the authors speculate.) However, if a hot-milk nightcap seems to help you catch z's, drink up. A little placebo effect never hurt anyone.
