Vagus Nerve Exercises
Vagus nerve exercises are practices intended to stimulate parasympathetic activity through breathing, humming, cold exposure, gargling, or similar techniques. These methods are thought to influence vagal signaling, which helps regulate heart rate, digestion, and stress responses. They are used to promote relaxation and autonomic balance, although the strength of evidence varies by technique.
