In this episode, Dr. David Hanscom talks with Dr. Joshua Smyth about the nature and mechanisms for unwanted repetitive thought (URT) patterns. These are thought patterns that persist over time and can have a negative effect on a person’s health and psychology. Dr. Smyth explains that these thoughts often have lots of very emotional associations and can be very experiential / visual. Ironically because of this, trying to suppress them consciously typically just reinforces them. They can damage our health because they trigger the body’s threat response.
