an integrated network of psychological and physiological interactions linking emotions and the physical manifestation of psychological distress. Emotions, both positive and negative, are the most important component of the nervous and endocrine systems, directly affecting the activity of the autonomic nervous system, hormonal secretion and the function of the immune system. This determines the predisposition of a person to the development of psychosomatic disorders. When experiencing persistent negative emotions such as anxiety, anger, or sadness, physiological responses associated with chronic stress are activated, such as increased secretion of cortisol and adrenaline, heart palpitations, increased blood pressure, and increased inflammation. All these factors lead to a weakening of biological immunity and fatigue of vital organs, which creates conditions for the occurrence of psychosomatic symptoms, such as cardiovascular diseases, gastrointestinal disorders, chronic headaches, skin and respiratory diseases. Negative emotions also affect cognitive function, limiting the ability to solve problems and weakening psychological resilience, psychological immunity, and self-efficacy. This increases negative physical reactions and slows recovery. Positive emotions such as joy, contentment, and enthusiasm act as an important protective factor, reducing the activation of stress responses and stimulating the production of neurochemicals such as endorphins, serotonin, and dopamine, which improve mood, relieve pain, and improve immune system function. Positive emotions also contribute to increased psychological resilience, self-confidence, and adaptability, helping a person to better cope with stress, preventing it from manifesting itself in the form of physical symptoms.
