A nightcap is a drink taken shortly before bedtime. For example, a small alcoholic drink or glass of warm milk can supposedly promote a good night's sleep.[1][2]

Alcoholic nightcaps and sleep[]

Traditional nightcaps include brandy, bourbon, and cream-based liqueurs such as Irish cream. Wine and beer can also function as nightcaps.[3]

In folk medicine, consuming a nightcap is for the purpose of inducing sleep. Alcohol is not recommended by many doctors as a sleep aid because it may interfere with sleep quality.[4] But, in low doses, alcohol has sleep-promoting benefits,[1] and some popular sleep medicines include 10% alcohol,[5] although the effects of alcohol upon sleep can wear off somewhat after several nights of consecutive use.[6]

Non-alcoholic[]

A nightcap was originally alcoholic, since it makes the drinker feel warm and helps them sleep, just like the garment of the same name.[7] However, warm milk is often recommended as a nightcap for inducing sleep. It contains both tryptophan and calcium,[8] which both help induce sleep. The flavor of the warm milk can be improved by adding a small amount of liqueur or vanilla extract, which contains ~45% alcohol, which may promote sleep as well. Alternatively, honey can improve the flavor.[8] The effectiveness of warm milk for inducing sleep is disputed.[9]

In 1930, Ovaltine was advertised as "the world's best 'night-cap' to ensure sound, natural sleep".[7]
