Nervous System · definition
A division of the autonomic nervous system involved in many functions associated with rest, digestion, conservation of energy, and routine organ regulation.
How the term is used
It is often summarized as rest-and-digest, although the body is more complex than a simple on/off switch between two states.
Why it matters
It helps readers understand why parasympathetic activity is useful without treating it as a permanent wellness goal.
