Study Reveals Gut Microbiota's Role in Stress Regulation via Circadian Rhythms

Researchers identify specific gut bacteria that modulate stress responses, paving the way for new mental health therapies.

The study highlights the interaction between gut microbiota and the body's circadian rhythms in regulating stress responses.
Depletion of gut bacteria leads to hyperactivation of the hypothalamic-pituitary-adrenal (HPA) axis, affecting stress responsivity throughout the day.
Limosilactobacillus reuteri is identified as a key bacterium influencing stress hormone secretion in a time-dependent manner.
Findings suggest potential for microbiome-based therapies to manage stress-related mental health conditions like anxiety and depression.
Maintaining a healthy gut microbiome is crucial for stress regulation, especially in modern lifestyles that disrupt natural circadian cycles.
