A diverse microbiota will improve sleep quality and overall health

A study conducted by American scientists showed a link between the intestinal microbiome and sleep quality. This opens the way to new methods of prevention of many diseases associated with insufficient microbiota composition, such as Parkinson's disease, depression, autoimmune diseases, and other pathologies.

Previous studies have shown that poor sleep negatively affects the gut microbiome, which in turn leads to additional health problems: the risk of psychoemotional problems in the short term increases, and increases the likelihood of cancer and cardiovascular disease in the long term. The authors of the new study show a two-way link between the human brain and its intestinal microbiome and claim that the more diverse the microbiota is, the better are the sleep and overall human health.

They conducted an experiment involving 26 people. With the help of special devices, the scientists observed the quality and duration of sleep of the subjects, as well as how many times they woke up during the night.

The results showed that people with quality and full sleep had a "rich" composition of the intestinal microbiota.

The authors note that several factors affect the diversity of the microbiome. One of them is genetic: some people are initially predisposed to have a more diverse intestinal microbiota. The other involves taking some medications, including antibiotics. Diet also plays an important role.

The team of scientists found a correlation between gut microbiota and sleep physiology, immune system, cognitive abilities, emotions. Together, they say their findings could help develop new therapeutic strategies for manipulating the microbiome to improve patients' sleep quality.
