In this episode, Dr. David Hanscom talks with physiatrist and pain management specialist David Clawsen, MD. He explains how the body’s many defenses against threats evolved from the cellular to the organism level. He details the redundant signaling systems the body uses to coordinate a threat response, and how the immune system provides both defense and healing / repair.

Dr. David Clawsen is a Physiatrist, based in Seattle, with backgrounds in neurologic, cancer, spine and sports rehabilitation, and pain management. He is interested in the different physiologic states that underpin illness and disease versus wellness and health, as determined by whether we are in threat versus safety.
