A glass of warm milk at bedtime has been a go-to remedy for relaxation and sleep for generations, and you may have heard that it actually works. But is there any truth to the idea that milk can improve sleep, or is it simply a comforting ritual?
Globally, millions struggle to get enough rest, with the CDC reporting that a third of adults in the U.S. alone fall short of the recommended hours of sleep. As the search for simple ways to relax and improve sleep quality grows, warm milk remains a popular choice. So, what is it about milk that may help us drift off more easily? Here’s what we know.
How Might Milk Impact Sleep?
Although there is limited research specifically on milk and sleep, some studies have shown that dairy products can contribute to better sleep quality for certain individuals. The exact reasons aren’t fully understood, but a few theories involve milk’s nutrient profile and the calming routine itself.
What’s in Milk That Might Help You Sleep?
Milk contains tryptophan, an amino acid that helps your brain produce serotonin, which supports a calm mood. It also plays a role in the production of melatonin, a hormone that regulates sleep. However, it’s worth noting that a single glass of milk may not provide enough of these compounds to dramatically alter your sleep.
The Power of a Comforting Habit
Some experts suggest that the psychological comfort associated with drinking warm milk could be the real benefit. The act of preparing and sipping a warm beverage can be calming in itself, signaling to your brain that it’s time to relax. Additionally, this practice may remind some people of the comforting routines from childhood, helping them unwind and prepare for a night of restful sleep.
Final Thoughts
In the end, while milk contains certain compounds that are linked to sleep, its true power might come from the relaxing ritual itself. If you find that it helps you wind down, then a glass of warm milk could be a simple, soothing addition to your evening routine.
