Breastfeeding helps babies sleep better at night…

I’ve always believed that breastmilk was best for babies, because God perfectly designed it to nourish babies (He created the human body, so He would know what formula would be best, right?!). However, I always find it fascinating to discover the different ways in which breastmilk and babies are perfectly suited for each other. The article below explores one such aspect of breastmilk. Enjoy!

“Sleep Inducers” in Breastmilk Change over 24-Hour Period

Breast milk contains various ingredients, such as , which perform a very important role in regulating babies’ . The new study, published recently in the journal Nutritional Neuroscience, confirms that the composition of changes quite markedly throughout the day.

The scientists looked for three nucleotides in breast milk (adenosine, guanosine and uridine), which excite or relax the central nervous system, promoting restfulness and sleep, and observed how these varied throughout a 24-hour period.

The milk, collected from 30 women living in Extremadura, was expressed over a 24-hour period, with six to eight daily samples. The highest nucleotide concentrations were found in the night-time samples (8pm to 8am).

“This made us realise that milk induces sleep in “, Cristina L. Sánchez, lead author of the article and a researcher at the Chrononutrition Laboratory at the University of Extremadura, tells SINC.

“You wouldn’t give anyone a coffee at night, and the same is true of milk – it has day-specific ingredients that stimulate activity in the infant, and other night-time components that help the baby to rest”, explains Sánchez.

In order to ensure correct nutrition, the baby should be given milk at the same time of day that it was expressed from the mother’s breast. “It is a mistake for the mother to express the milk at a certain time and then store it and feed it to the baby at a different time”, points out the researcher.

The benefits of breast milk

The World Health Organization (WHO) says breast milk is the best food for the newborn, and should not be substituted, since it meets all the child’s physiological requirements during the first twelve months of life. It not only protects the baby against many illnesses such as colds, diarrhea and sudden infant death syndrome, but can also prevent future diseases such as asthma, allergies and obesity, and promotes intellectual development.

The benefits of breastfeeding also extend to the mother. Women who breastfeed lose the weight gained during pregnancy more quickly, and it also helps prevent against anemia, high blood pressure and postnatal depression. Osteoporosis and breast cancer are also less common among women who breastfeed their children.
