The Cost of Hidden Stress Trained to consider mind and body separately, physicians are often helpless in arresting the advance of most of the chronic diseases. Gabor Mat has found that in all of these chronic conditions, there is a common thread: people afflicted by these diseases have led lives of excessive stress, often invisible to the individuals themselves. From an early age, many of us develop a psychological coping style that keeps us out of touch with the signs of stress. So-called negative emotions, particularly anger, are suppressed. Dr. Mat writes with great conviction that knowledge of how stress and disease are connected is essential to prevent illness in the first place, or to facilitate healing.
