Parasympathetic Nervous System

Meaning

The Parasympathetic Nervous System (PNS) is one of the two main branches of the autonomic nervous system, responsible for the body’s “rest and digest” or “feed and breed” functions. It works in opposition to the sympathetic nervous system, promoting physiological states associated with energy conservation, repair, and nutrient processing. Key functions include slowing the heart rate, increasing intestinal and glandular activity, and relaxing sphincter muscles. In the context of hormonal health, the PNS is crucial for optimal digestion, detoxification, and reproductive function, as chronic suppression by sympathetic overdrive can impair metabolic and endocrine processes. Cultivating PNS activation is a cornerstone of stress management and HPA axis recovery protocols.
