The phrase
"parasympathetic tone" refers to the level of activity or control exerted by the parasympathetic nervous system in the body. It indicates how relaxed or calm a person is, as the parasympathetic system is responsible for calming down the body's functions and promoting rest and digestion. A higher
parasympathetic tone means the body is more relaxed, while a lower tone indicates a more alert and active state.
