How Gut Bacteria Affect Sleep Problems and Ways to Improve Them

Evidence suggests that the microbiota-gut-brain axis (MGBA) may play an important role in insomnia.

• Gut microbiota and their metabolites could influence sleep-wake patterns through various biological pathways.
• Insomnia may be linked to alterations in gut microbiota, creating a feedback loop with stress and immune responses.
• Animal and clinical studies indicate a close association between gut microbial imbalances and insomnia symptoms.
• Factors such as diet, lifestyle, and medications may affect the functioning of the MGBA.
• Interventions targeting the MGBA, like dietary changes and probiotics, may offer new strategies for managing insomnia.
• Current findings are primarily based on animal research and observational studies, indicating a need for more robust clinical trials.
