The vagus nerve plays a crucial role in regulating the parasympathetic nervous system, which controls the "rest and digest" functions of the body. It helps modulate inflammation, heart rate, and digestion.

When the vagus nerve is not functioning optimally, it can contribute to a wide range of chronic health issues, including anxiety, depression, brain fog, and inflammatory conditions.

Common factors that can impair vagus nerve function include chronic stress, poor gut health, lack of movement/exercise, and an inflammatory diet high in processed foods.

Simple vagus nerve stimulation techniques like diaphragmatic breathing, gargling, and listening to certain music can help reboot vagus nerve function and shift the body into a parasympathetic state.

Tools like transcutaneous vagus nerve stimulators can also be used to directly target and support vagus nerve activity.
