Gut microbes can control the body’s response to stress throughout the day. They do this by producing different hormones during the day and night, according to a study published in the journal. Cell Metabolism.
The adrenal glands, which secrete stress hormones, as well as some parts of the brain, the hypothalamus and the pituitary gland, form a single system that is responsible for the body’s response to stress. Depletion of the gut microbiota can lead to hyperactivation of this system in mice. This has been demonstrated by a new study in which scientists found gut bacteria play an important role in the stress response.
They turned out to be lactic acid bacteria Limosilactobacillus reuteri. They control the release of stress hormones throughout the day. In parallel, changes occur in the functioning of certain regions of the brain. Gut bacteria and the brain’s circadian rhythms together are responsible for changing the stress response throughout the day.
Modern lifestyles disrupt circadian rhythms due to irregular sleep, high stress levels and poor nutrition. New research highlights the importance of gut microbes in stress management. The results could form the basis of new microbe-based drugs to treat stress-related mental disorders such as anxiety and depression. These conditions are often associated with disturbances in circadian rhythms and sleep cycles.
