Warm Milk Helps You Sleep

Go To
2 out of 3 for the lactose intolerant is not so bad.

"Warm milk helps you sleep, LaForge. You should try it."
Guinan, Star Trek: The Next Generation, "Hollow Pursuits"

First night in a strange place? Warm milk! Can't sleep? Warm milk! Character has a nightmare? Warm milk!

The idea of warm milk being a perfect sleeping aid is Older Than Feudalism, and can be found in most cultures that have milk-producing animals.

This can be Truth in Television, medically speaking. Milk has opiate precursors in it, which is part of the reason why it tends to be a go-to sleep aid for some people, especially since heating the milk seems to help make said opiates a little more effective. It also contains the amino acid tryptophan which has a relaxing and calming effect, and is a precursor for the hormone melatonin, crucial in maintaining your circadian rhythm and allowing you to sleep properly. However, its effectiveness can greatly vary from person to person. There's also the fact that it's high in fat, protein and carbs, meaning that it can make someone sleepy in the same way any large meal can.

Given its somniferous effects on some people, warm milk is a real-world example of the Frothy Mugs of Water trope, being easy to access and legal at any age, and capable of mirroring drunkenness through the drowsiness it imparts on some of its drinkers.

Subtrope of Comfort Food. A very likely trope to show up in an Insomnia Episode. A character who offers warm milk is frequently established as a caregiver type, if not a Parental Substitute. It can also be used to deliberately sedate another person.
