Scientists have uncovered compelling evidence highlighting the critical role of the microbiota-gut-brain axis in regulating sleep and contributing to sleep disorders. A recent comprehensive review published in Brain Medicine synthesized findings on how gut microbiota composition and function intersect with sleep disturbances, offering new insights into mechanisms, biomarkers, and potential microbiome-targeted interventions.

Sleep, essential for physical and mental well-being, is influenced not only by brain circuits but also by the trillions of microbes residing in the gastrointestinal tract. These microbes communicate with the brain through metabolic, neural, and immune pathways, comprising a bidirectional network known as the microbiota-gut-brain axis. Disruptions in this axis are con
