Talk about mental health is no longer limited to the brain alone, as recent studies have revealed a close connection between the intestine and mood, in what is known scientifically as the “gut-brain” axis. This discovery changed scientists’ view of the digestive system, which is no longer merely responsible for digesting food, but has come to be seen as an influential element in psychological balance and mood.
Researchers confirm that the intestine contains a complex network of nerve cells, sometimes known as the “second brain,” due to its ability to communicate directly with the brain via the vagus nerve. This continuous communication allows for the exchange of nervous and hormonal signals, which explains how digestive system disorders can reflect on the psychological state of the individual.
Beneficial bacteria and their role in improving mood
The beneficial bacteria in the intestine, known as the “microbiome,” play an essential role in producing a number of important neurotransmitters, such as serotonin, which is known as the happiness hormone. It is estimated that a large percentage of serotonin in the body is produced within the digestive system, and not in the brain as some believe.
When there is an imbalance in the beneficial bacteria as a result of malnutrition, stress, or excessive use of antibiotics, symptoms such as anxiety, depression, and sleep disturbances may appear. Therefore, nutrition experts stress the importance of eating foods rich in probiotics and fiber, such as natural yogurt, leafy vegetables, and whole grains, to support intestinal health and enhance psychological stability.
Digestive disorders and their effect on the psychological state
Some people suffer from chronic problems such as irritable bowel syndrome, bloating, or indigestion, and these symptoms often coincide with clear mood swings. Specialists confirm that tension and psychological pressure can negatively affect bowel movement and its functions, creating a mutual influence between the psychological state and the health of the digestive system.
An unhealthy lifestyle, including lack of sleep and excessive consumption of processed foods and sugars, may impair the balance of beneficial bacteria, which in turn affects daily mood and energy. Therefore, doctors advise following a balanced diet, engaging in regular physical activity, and maintaining a good level of hydration.
Practical steps to support gut health and improve mood
Among the steps that experts recommend to improve intestinal health are: eating fermented foods, reducing stress through meditation and deep breathing exercises, and ensuring adequate sleep. It is also preferable to limit the consumption of antibiotics without medical necessity, due to their effect on beneficial bacteria.
In light of increasing research on the relationship between the intestines and mood, it is clear that taking care of the digestive system represents an essential foundation for comprehensive health, both physical and psychological. Internal balance begins with the intestines, and improving the quality of food and lifestyle may be an effective step towards a more stable mood and a more comfortable life.
