Our body gets goosebumps when we're cold or scared because little muscles on our skin start working like tiny helpers.
What Are Goosebumps?
When you’re cold, your body wants to stay warm. It uses small muscles called arrector pili, which are attached to each of your hairs. These muscles pull the hair up, making it stand straight. That’s why your hair looks all prickly, like a tiny hedgehog!
What Happens When You’re Scared?
When you're scared, your body gets ready for action, just like when you run away from something scary. Your heart beats faster, and those same little muscles on your skin also go to work. They make your hair stand up, too, not because it’s cold, but because you're excited or nervous.
It’s like when you’re playing hide-and-seek and you hear someone coming. You might feel a shiver down your back, and suddenly your whole body feels all tingly. That’s goosebumps doing their job!
