German public broadcaster ARD detailed a breathing exercise designed to stimulate the vagus nerve to reduce stress quickly [1].
This technique matters because it targets the body's internal mechanisms to counteract the physiological effects of anxiety. By activating the vagus nerve, individuals can potentially lower their heart rate, and reduce muscle tension during high-stress moments [1, 3].
The maneuver requires the person to be in a seated position [1, 2]. While sitting, the individual places their thumb in their mouth and exhales forcefully [1, 2]. This specific exhalation should last between three and five seconds [1].
ARD said the vagus nerve functions as a natural emergency brake for the stress response [1, 3]. When stimulated through this method, the nerve signals the body to calm down, which helps stabilize breathing and heart rate [1, 3].
Because the exercise is designed for quick activation, it can be performed in most indoor environments. The focus is on the immediate physical shift in the nervous system rather than long-term meditative practice [1, 2].
“The vagus nerve acts as a natural ‘emergency brake’ for the stress response.”
The promotion of vagus nerve stimulation highlights a growing interest in somatic interventions for mental health. By utilizing a physical 'hack' to trigger the parasympathetic nervous system, this method provides a non-pharmacological tool for immediate stress management, though it focuses on symptom mitigation rather than addressing the root causes of stress.
