We get goosebumps when we are cold or excited because our body is trying to keep us warm or show how we feel.
How It Works
When you're cold, your skin gets a little chilly. Your body wants to stay warm, so it sends tiny messages to your hair follicles, which are like little pockets in your skin that hold your hair. These messages tell the hair follicles to stand up, making your hairs rise.
This is why you see little bumps on your skin, they're like tiny hills made by your rising hairs! When all your hairs stand up together, it looks like goosebumps, just like when a goose gets cold and its feathers puff up.
When You’re Excited
When you’re excited or scared, your body also sends messages to your hair follicles. This time, it’s not because you're cold, it's because your body is reacting to strong feelings. Your hairs rise again, making goosebumps appear on your arms and face.
It's like your body is saying, "Hey, look at me! I'm feeling something amazing!"
