New research has shone further light on the connection between the gut microbiome and sleep.
The research follows similar studies carried out on mice and fruit flies earlier this year, in which scientists found changes to the gut microbiome could lead to high blood pressure and fragmented sleep, as well as early death from sleep deprivation. The latest work carried out at the University of Tsukuba focuses on the role this bacteria plays in affecting sleep via the production of the neurotransmitters serotonin and dopamine.
To investigate this connection, the researchers gave a group of mice strong doses of antibiotics over the course of four weeks. This depleted the diversity of bacteria in their intestines, which led to significant differences in their metabolites compared to a control group of mice fed the same diet.
