The sympathetic and parasympathetic nervous systems are two parts of the autonomic nervous system. This system controls things in our bodies that we don't think about, like breathing and heartbeat.

Here’s How They’re Different:

• Sympathetic Nervous System:

  • This part is often called "fight or flight."
  • It makes your heart beat faster, your pupils get bigger, and it slows down your digestion.
  • For example, if a bear is chasing you, this system helps you react quickly.

• Parasympathetic Nervous System:

  • This is known as "rest and digest."
  • It slows your heart rate, makes your pupils smaller, and helps with digestion.
  • An example is when you relax after eating. This helps your body process the food better.

Together, these two systems work to keep your body balanced. They help you handle stress when you need to and allow you to relax when it’s time to rest.
