Description of the Sympathetic and Parasympathetic Nervous Systems
Sympathetic and parasympathetic nervous systems are two crucial autonomic nervous system mechanisms (Weissman & Mendes, 2021). They help ensure human bodies sustain homeostasis and react suitably depending on the existing circumstances. Specifically, the sympathetic nervous system can also be identified as a ‘flight’ or ‘fight’ reaction system. When active due to stress, perceived risk, or any undesirable event, it prepares an individual’s body for sudden action. The activation causes physiological changes like rapid breathing, stress hormone generation, and boosted heart rate. On the other hand, the parasympathetic nervous system can also be recognized as the ‘rest and digest’ response system. It functions during recovery and relaxation moments – this restores and conserves energy. When it is active, it neutralizes the sympathetic system’s effects by decreasing the heart rate, enabling nutrient absorption and food digestion.
