Parasympathetic nervous system
From MEpedia, a crowd-sourced encyclopedia of ME and CFS science and history

The Parasympathetic nervous system (PNS or PSNS) affects the heart, lungs, eyes, digestive system and blood vessels. It does the opposite of the sympathetic nervous system and the two nervous systems balance each other's effects. While the Sympathetic nervous system has "fight or flight" responses, the Parasympathetic nervous system lets the person "rest and digest".[citation needed]
