Researchers have reviewed multiple studies and found growing evidence that the bacteria in your gut may influence how well you sleep. Using data from recent trials, the review reveals that people with sleep issues—such as insomnia or apnea—often show altered gut-microbe profiles compared with those who sleep well. The scientists noted that certain microbial strains appear less abundant in sleep-impaired individuals, and that these changes may affect inflammation and the nervous system during sleep. While it’s too early to say that gut bacteria-fixing treatments will cure sleep disorders, this link opens a fresh area for investigation. Improving diet and gut health may play a role in better rest.
