The Vagus Nerve: Heart, Health, and Healing

This chapter explores the crucial role of the vagus nerve in regulating heart rate variability (HRV) and its implications for health outcomes, including heart health, mental well-being, and inflammation. By examining the interplay between genetics, lifestyle, and vagal activity, the chapter highlights ongoing research and practical applications like biofeedback and vagus nerve stimulation. Additionally, it addresses the importance of understanding the relationship between early trauma, anxiety, and HRV, as well as recent efforts in mental health interventions for traumatized populations.
