Psychoneurobiology (or psychoneuroimmunoendocrinology) studies how the mind, the nervous system, the endocrine system, and the immune system communicate. It explains why psychological stress has measurable physical effects: the hypothalamic-pituitary-adrenal axis releases cortisol, the autonomic nervous system and the vagus nerve adjust the response, and all of this modulates inflammation, sleep, and mood.
It is the framework that connects goals such as anxiety, depression, chronic stress, or panic disorder with mechanisms such as cortisol, the HPA axis, neurotransmitters, the vagus nerve, and the gut-brain axis. Interventions on sleep, breathing, exercise, or the microbiota act precisely on these pathways.
