Neuroscience of Anxiety & the Parasympathetic Nervous System | Dr. Rami Nader

Anxiety is a common experience that can significantly affect a person's quality of life. It can manifest itself in various ways, including constant worry, physical symptoms, and feelings of helplessness. Fortunately, our bodies have a natural system that can help manage anxiety and regulate our stress response. This system is known as the parasympathetic nervous system. The parasympathetic nervous system works as a counterbalance to the fight or flight response, which is activated when we feel threatened. When our bodies are in this state, we experience a surge of adrenaline that prepares us to either fight or flee from danger. However, the parasympathetic nervous system helps us calm down and relax by slowing down our heart rate, lowering our blood pressure, and reducing our breathing rate. By activating this system, we can reduce our anxiety and promote a sense of calmness. In this video, we explore the science behind the parasympathetic nervous system and how it can help manage anxiety. We discuss the various brain regions involved in regulating the parasympathetic nervous system, including the amygdala and prefrontal cortex and the role of the vagus nerve. The video also explains the limitations of relying solely on the parasympathetic nervous system to manage anxiety and how cognitive behavioral therapy can be a more effective long-term solution to anxiety.
