Intestinal health is closely related to stress levels, and there is a bidirectional interaction between the two, which is often referred to as the "gut brain axis" in the medical community. On the one hand, long-term exposure to high pressure can activate the body's stress response system, affecting autonomic nervous system function and endocrine balance, thereby altering intestinal peristalsis rhythm, reducing digestive enzyme secretion, weakening intestinal barrier function, and disrupting intestinal microbiota structure, which may cause digestive discomfort symptoms such as bloating, abdominal pain, constipation, or diarrhea. On the other hand, imbalanced gut microbiota or chronic intestinal inflammation can also transmit information to the brain through the vagus nerve and immune signaling pathways, affecting the emotional regulation center, exacerbating negative emotions such as anxiety and depression, and forming a vicious cycle of "stress gut disorder emotional deterioration". Therefore, scientific management of stress, maintaining a regular schedule, balanced diet, moderate exercise, and supplementing with prebiotics and probiotics can all help maintain a healthy gut brain interaction and improve overall physical and mental health.
