New research has unveiled how gut bacteria play a key role in regulating stress by interacting with circadian rhythms, opening possibilities for microbiome-based therapies for mental health. Researchers found that depletion of certain gut bacteria can lead to time-specific increases in stress responses through the HPA axis, the body's central stress response system. Specific bacteria, such as Limosilactobacillus reuteri, were identified as crucial to modulating stress hormones throughout the day.
