Psychosomatics
Psychosomatics studies the bidirectional relationship between mind and body, recognizing that psychological processes can influence physical health and vice versa. Since antiquity, medicine has acknowledged the connection between emotions and disease — Hippocrates already spoke of the effects of humors on the body. However, Cartesian dualism artificially separated mind and body for centuries, and it was not until the twentieth century that psychosomatic medicine emerged as a formal discipline, seeking to reunify what had never truly been separate. Contemporary evidence demonstrates that chronic psychological stress can alter immune, cardiovascular, gastrointestinal, and endocrine function.
Franz Alexander, one of the pioneers of psychosomatic medicine, proposed the specificity theory in the 1950s, suggesting that specific emotional conflicts generated specific diseases. He identified seven classic psychosomatic disorders: peptic ulcer, bronchial asthma, rheumatoid arthritis, ulcerative colitis, essential hypertension, neurodermatitis, and thyrotoxicosis. Although the idea of a direct correspondence between a conflict and a disease has been superseded, Alexander deserves credit for establishing that emotions can have real and measurable physiological consequences. The concept of alexithymia — the difficulty in identifying, describing, and processing one's own emotions — subsequently emerged as an important risk factor for psychosomatic disorders, suggesting that unrecognized and unexpressed emotions may manifest somatically.
The biopsychosocial model, proposed by George Engel in 1977, replaced mind-body dualism with an integrative framework that considers biological, psychological, and social factors as inseparable dimensions of health and disease. Psychoneuroimmunology has provided the concrete mechanisms for this interaction, demonstrating how psychological stress activates the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system, altering immune function and increasing vulnerability to disease. Research on adverse childhood experiences (ACEs) has shown a dose-response relationship between early traumatic experiences and chronic diseases in adulthood. Contemporary psychosomatic medicine integrates psychotherapeutic, pharmacological, and behavioral medicine interventions to address conditions where psychological factors play a significant role.
