Sympathetic Nervous System

/ˌsɪm.pəˈθɛt.ɪk ˈnɜː.vəs ˈsɪs.təm/noun
ELI5 mode

The sympathetic nervous system is a key component of the autonomic nervous system that activates the body's rapid 'fight-or-flight' response to stress or danger, increasing heart rate and redirecting blood flow to essential muscles. It operates involuntarily, influencing functions like pupil dilation and sweat production, and in today's fast-paced world, it's often implicated in chronic conditions like anxiety and hypertension. This system contrasts with its counterpart by prioritizing survival over rest.
