direct physical manifestation of psychological disorders. The autonomic nervous system (ANS) acts as a link between the brain and the body, regulating unconscious vital functions such as heart rate, blood pressure, breathing, digestion, sweating, and hormonal activity. Under the influence of chronic stress or repressed emotions in the autonomic nervous system, there is an imbalance between the sympathetic nervous system, which is responsible for the fight-or-flight response, and the parasympathetic nervous system, which is responsible for returning the body to a state of relaxation.
