There is a relationship between gut bacteria and children’s sleep

This is what Swiss researchers have just shown. This is further evidence that the belly is our second brain.

We already knew the link between germs and sleep in adults, but these researchers from the universities of Zurich and Friborg have just shown that this interaction occurs very early, before the age of one year. They have already followed 162 infants at home for ten days. Their parents had to note bedtime, wake-up times, and meals. These children’s sleep time was recorded using a motion sensor they wore on their ankles, and some were also fitted with sensors on the head to monitor their brain activity. At the same time, these researchers took samples from diapers to monitor the status of their intestinal microbiota.

Their conclusions are clear: children with poor intestinal flora, and therefore containing fewer microorganisms, also experience a poorer quality of rest at night, with more disturbed sleep, and interrupted sleep. Suddenly they sleep more during the day. These researchers also suggest that microbiota diversity is associated with increased brain activity in these children: from very early childhood, what happens in the gut thus influences brain development, they point out.

In adults, the spore is a mass of two kilograms of microorganisms (bacteria, microbes, viruses) that are involved in digestion, but also in the manufacture of various molecules that regulate our nervous and immune system. This is how the work of these residents of our gut can affect our sleep and that depleted or imbalanced microbes can promote mood disorders, obesity, or certain inflammatory diseases.

You can take care of the intestinal flora using probiotics, but the result is not guaranteed, and it is better to seek advice, because not all cocktails are alike. Other than that, the best way to take care of your microbes in general is to eat a variety of meals. Be careful not to abuse sugars, animal fats, and processed products that stimulate the bacteria responsible for inflammation. While foods containing fiber (green vegetables, raw vegetables or fruits) on the contrary promote the development of beneficial microorganisms for the intestine.
