Vagal tone research has the potential to offer insight into social behavior, social interactions, and human psychology. Much of this work has been focused on newborns and children . [ 26 ] Baseline vagal tone can be used either as a potential predictor of behavior or as a signal of mental health (particularly emotion regulation , anxiety , and ...
A vagal maneuver is an action used to stimulate the parasympathetic nervous system by activating the vagus nerve. The vagus nerve is the longest nerve of the autonomic nervous system and helps regulate many critical aspects of human physiology, including heart rate, blood pressure, sweating, and digestion through the release of acetylcholine .
Flexible PNS activity, indexed by vagal tone, helps regulate the heart rate and has been linked to a healthy stress response as well as numerous positive health outcomes. [45] Vagal tone has been found to predict both positive emotions and social connectedness, which in turn result in increased vagal tone, in an "upward spiral" of well-being. [46]

Under resting conditions, vagal tone prevails and variations in heart period are largely dependent on vagal modulation. The vagal and sympathetic activity constantly interact. Because the sinus node is rich in acetylcholinesterase, the effect of any vagal impulse is brief because the acetylcholine is rapidly hydrolyzed.
Personally, the skill helps me shift gears with more fluidity when my kid is suddenly home sick, derailing a work day. Or it allows me to handle traveling hiccups with grace and patience.
This reduces sympathetic tone to vascular smooth muscle. [9] This reduces heart rate and vascular resistance. [9] Digoxin increases vagal tone from the vasomotor centre, which decreases pulse. [7] G-series nerve agents have their most potent effect in the vasomotor center. [10]
