What Happens When You Increase Parasympathetic Tone? Increasing stimulation of the parasympathetic nervous system decreases heart rate and blood pressure as well as the size of the pupil. At the same time, it increases digestion, urination, defecation and sexual arousal.

In contrast, authors of a recent field study reported a decrease in respiratory sinus arrhythmia associated with indoor traffic noise exposure during sleep, consistent with an effect mediated by a reduction in parasympathetic tone (Graham et al.

en.wikipedia.org/wiki/Vagal_tone

Vagal tone refers to activity of the vagus nerve, the 10th cranial nerve and a fundamental component of the parasympathetic branch of the autonomic nervous system. This branch of the nervous system is not under conscious control and is largely responsible for the regulation of several body compartments at rest.

en.wikipedia.org/wiki/Parasympathetic_tone

The main mechanism by which the parasympathetic nervous system acts on vascular and cardiac control is the so called respiratory sinus arrhythmia (RSA). RSA is described as the physiological and rhythmical fluctuation of heart rate at the respiration frequency, characterized by heart rate increase during inspiration and decrease during expiration.

Reduced parasympathetic tone and increased sympathetic tone during rest , a blunted parasympathetic response during a mental task (mental arithmetic) , and lowered levels of respiratory sinus arrhythmia (measure of parasympathetic activity) , have been previously reported in ASD. This evidence collectively suggests decreased parasympathetic ...

The stronger your vagus response or vagal tone is the stronger your body is at regulating blood glucose levels, reducing the likelihood of diabetes, stroke and cardiovascular disease. Low vagal tone, however, has been associated with chronic inflammation and if low vagal tone persists, regulation of inflammation can become less effective.
