What is the sleepy chemical in breast milk?

The Sleepy Chemical in Breast Milk: Melatonin
Breast milk is often hailed as the gold standard for infant nutrition, but it also contains fascinating components that influence a baby’s sleep patterns. One of the key players in this regard is melatonin, a hormone known for its role in regulating sleep-wake cycles. Research indicates that the composition of breast milk varies throughout the day, with higher levels of melatonin found in milk expressed at night. This phenomenon has led to the term “night milk,” which is believed to be particularly beneficial for promoting sleep in infants.
How Melatonin Works in Breast Milk
Melatonin is produced by the pineal gland in response to darkness, signaling to the body that it is time to sleep. In the context of breastfeeding, the presence of melatonin in night milk may help synchronize an infant’s circadian rhythms, encouraging longer and more restful sleep. Studies have shown that this nighttime milk not only contains increased melatonin but also higher levels of nucleotides, which are thought to further promote sleep.
The implications of this are significant for new parents. For instance, mothers who pump breast milk during the day and feed it to their babies at night might inadvertently disrupt their child’s sleep patterns. This is because the milk consumed at night lacks the elevated melatonin levels that naturally occur in milk produced during those hours.
The Broader Impact of Breast Milk Composition
The dynamic nature of breast milk composition is a remarkable aspect of maternal biology. It adapts not only to the nutritional needs of the growing infant but also to the time of day, potentially influencing sleep quality. This adaptability underscores the importance of breastfeeding, as it provides not just essential nutrients but also bioactive compounds that can affect an infant’s development and well-being.
In summary, melatonin is the sleepy chemical in breast milk that plays a crucial role in helping infants establish healthy sleep patterns. The presence of this hormone in night milk highlights the intricate relationship between maternal biology and infant health, offering insights into how breastfeeding can support better sleep for newborns.

Is melatonin in breast milk a myth?

Because your body naturally produces melatonin, some of it passes into your breast milk. Typically, the concentration of melatonin will be higher in the milk that you produce at night than in the milk you produce during the day.

Why shouldn’t milk be taken at night?

Why is breastfeeding so exhausting?

Oxytocin, also known as “the love hormone,” packs a powerful punch that, while supporting healthy breastfeeding/chestfeeding, has one potentially dangerous side-effect: it can make people tired.

What makes babies sleepy in breastmilk?

However, since breast milk is more easily digestible than formula, babies who breastfeed are likely to wake up more frequently than formula-fed babies, as they will get hungrier faster. However, the melatonin in breast milk will facilitate their sleep, so right after the feeding, they’ll go back to sleep easily.

What is the sleep inducer in milk?

Milk has long been known and used to promote sleep. The sleep-promoting effect of milk has been attributed to its psychological associations (i.e., the memory of a mother giving milk at bedtime) and its rich store of sleep-promoting components. One of these components is the essential amino acid tryptophan.

What is the ingredient in milk that makes you sleepy?

amino acid tryptophan
Why Does Warm Milk Make You Sleepy? Milk’s sleep-promoting properties might be due to the amino acid tryptophan. Tryptophan-enriched foods have been shown to improve sleep and mood in the elderly.

What is the sleep inducing substance in milk?

It was found that Night milk has exceptionally rich amounts of tryptophan and melatonin, and that rats given Night milk showed an increased circulating melatonin. Furthermore, a study conducted in elderly patients showed that Night milk improved sleep quality that resulted in a better daytime activity.

What is the sleep hormone in breast milk?

The melatonin concentration in breast milk varies in a circadian pattern, making breast milk a chrononutrient. The consumption of melatonin can induce the first circadian stimulation in the infant’s body at an age when his/her own circadian machinery is not functioning yet.
