The post-Cartesian dilemma: Reuniting the mind and body through psychoneuroimmunology.

While today, it might seem absurd to hear anyone claim that stress does not alter all aspects of the human experience, including behavioral, cognitive, affective, and physiological processes. Dr. Janice Kiecolt-Glaser started her career at a time when stress was primarily considered a neuroendocrine response with cardiovascular repercussions. She was part of a small group of innovative scientists who began to push the boundaries of stress research - many contemporary immunologists and virologist disputed their early results in 1980s and 90s - and, yet, they persevered by connecting psychological stress to altered immune function via stress-related neuroendocrine changes. As a clinical psychologist, she focused mainly on human research studies to advance the field of psychoneuroimmunology throughout her career. Her research demonstrates how adversity and psychosocial aspects of human experience alter physiological functioning, primarily immune, and health or, in other words, the embodiment of our lived experiences. This short review is a contextualized synthesis of Dr. Kiecolt-Glaser's key contributions to the fields of psychoneuroimmunology and health psychology and her influence on my present day thinking and research approaches, as well as potential steps forward in our post-pandemic world.
