Increased vagal tone refers to heightened activity of the vagus nerve, which is a key part of the parasympathetic nervous system. This nerve helps regulate various bodily functions, including heart rate, digestion, and respiratory rate. When vagal tone is increased, it can lead to a more relaxed state, promoting feelings of calm and reducing stress. Higher vagal tone is often associated with better overall health. It can improve heart health by lowering heart rate and blood pressure, and it may enhance emotional well-being by reducing anxiety and depression. Activities like deep breathing, meditation, and regular exercise can help boost vagal tone.
