Definition

Rest and digest is a phrase used to describe the state in which the body's parasympathetic nervous system promotes activities that conserve energy, enhance digestion, and reduce stress. It triggers responses such as decreased heart rate, increased intestinal activity, and relaxed muscles in the gastrointestinal tract.
