Your intestinal health may have an impact on your mood in your immune system, But it could also be the cause of Your poor sleeprevealed a study.
Specific types of intestinal bacteria were linked to insomnia risk by researchers, while insomnia itself was also linked to an abundance of Some “bugs” in the intestine.
InsomniaThis means that a person has difficulty falling and staying asleep, affects about a third of adults in the United Kingdom. It can be caused by anxiety, noise, alcohol, caffeine or quarter work, according to the NHS.
Several studies have explored the effects of the intestinal microbiome on various sleep characteristics, but it is not yet clear how different groups of groups of groups intestinal bacteria could affect the risk of insomnia.
The study, published in the journal General psychiatryused data on 386,533 people with insomnia of a previously study, data on the intestinal microbiome for 18,340 people from the Mibiogen alliance and for 8,208 people from the Dutch microbiome project with 71 groups of joint bacteria.
Their analysis revealed associations between specific intestinal microbes and insomnia.
Overall, a total of 14 groups of bacteria were positively associated with insomnia and eight groups showed a negative association.
Insomnia itself was associated with a reduction between 43% and 79% in the abundance of seven groups of bacteria and 65% with an increase of more than four times in the abundance of 12 other groups.
The researchers found that the odoribacter class of bacteria, in particular, was significantly associated with the risk of insomnia.
This type of bacteria plays a role in the production of short -chain fatty acids such as Butyrate, which can help maintain a healthy intestine.
However, there are certain limits to the study. All study participants were of European origin, so that the results may not be more widely applicable because the composition of the microbiome varies between the different ethnic groups and geographies, underline the researchers.
The diet and the lifestyle – which affect the microbiome – were not taken into account either. Although bacteria are linked to insomnia, these same bacteria can be shaped by eating, stress levels and the environment of a person.
“Overall, the intertwined effects of insomnia on the intestinal microbiota, and vice versa, represent a complex bidirectional relationship involving immune regulation, the inflammatory response, the release of neurotransmitters and other molecular and cellular pathways,” said study authors.
The authors conclude: “Our study offers preliminary evidence supporting a causal effect between insomnia and intestinal microbiota, providing valuable information for the future development of treatment plans inspired by the microbiome for insomnia.”
These treatment plans could include the use of probiotics, prebiotics or transplantation of fecal microbiota, they suggest.
