What Is the Autonomic Nervous System?

Your body has a secret helper that works automatically. It’s like having a robot inside you that takes care of things like your heartbeat, breathing, and digestion, without you even thinking about it. This helper is called the autonomic nervous system. When you’re scared or excited, it helps you react quickly; when you're relaxed, it lets your body rest and recover.
