Why Do We Get Butterflies When We Are Nervous?

That fluttering feeling is your body's ancient alarm system waking up. Long ago, if you heard a rustle in the bushes, you had to run or fight. Your brain tells your stomach to get ready for action by slowing down digestion. This stops your tummy from churning food normally, making it feel empty and wobbly. It is like your gut is doing little jumps of excitement.

The Connection

Your stomach has its own nerves that talk directly to your brain. When you are nervous, these nerves send messages that make the muscles in your stomach tighten or relax quickly. This rapid movement feels like wings fluttering inside you.
