You’ve heard of “Type A” and “Type B”, what is Type C personality? Common Type C traits include: excessively conscientious, avoids conflict, feels powerless, carries others’ burdens, wants to please others, doesn’t set sufficient personal boundaries, internalizes toxic emotions, maintains a constant facade of pleasantness.

Many people fall into this “pathologically nice” category and lack skills to become aware of and effectively communicate their needs. Unfortunately, Type C habits can harm our mental and physical health if taken too far; they have been scientifically linked to disease.

We first read about Type C in a book by Dr. Nasha Winters, The Metabolic Approach to Cancer. Some scientific studies on Type C include: Garsen, B. & Goodwin, K. (1999). On the role of immunological factors as mediators between psychosocial factors and cancer progression. Psychiatry Research 85(1):51-61;  Baltrusch, H. J., Stangel, W., & Titze, I. (1991); Stress, cancer and immunity: New developments in biopsychosocial and psychoneuroimmunologic research. Acta Neurologica, 13(4), 315–327.
