Can Stimulating the Vagus Nerve Ease Anxiety? What Science Says for Thai Readers
Anxiety is rising worldwide, including in Thailand, and a centuries-old nerve is drawing renewed attention as a possible ally: the vagus nerve. Known as the body’s “electrical information superhighway,” the vagus nerve is now under close scientific scrutiny as researchers explore its role in mood, inflammation, and stress responses. But can vagus nerve stimulation really help anxiety, and what should Thai readers know before trying popular methods?
The vagus nerve runs from the brainstem to the heart, lungs, and digestive system. It is a central component of the parasympathetic nervous system, the “rest and digest” system that counteracts the “fight or flight” response. By influencing breathing, heart rate, gut function, and immunity, the vagus nerve links physiology to mood. In Thailand, where mental health awareness is growing, many people are curious about whether stimulating this nerve can offer tangible benefits.
