When you're nervous, your brain sends a message telling your body to get ready for action. This makes your blood vessels shrink and your skin hairs stand up, that's why you feel like you have goosebumps or chills! It's like your body is trying to warm you up by making you look bigger and stronger.
Examples
- You get chills before giving a speech because your body thinks you're about to run away from danger.
- A child might feel cold and shiver when they have to go on stage for the first time.
- Feeling nervous during an exam can cause your arms to feel chilly even if the room is warm.
