Rest and digestion: The parasympathetic nervous system

When a person rests, meditates or reads a book, the parasympathetic nervous system is activated.

Also known as the “rest and digest” system, the parasympathetic nervous system is responsible for conserving energy and maintaining vital bodily functions, including digestion, urination, and defecation, especially when the body is at rest. The “rest and digest” system helps the body maintain homeostasis, or a relatively stable internal state, by balancing sympathetic nervous system activity that triggers the “fight or flight” response.
