Fact of the day: Did you know goosebumps actually have a purpose?

August 27, 2015

I was reading some articles the other day when I came across one about goosebumps. I don’t know why it caught my attention, but I guess I’ve just never known the purpose of them and thought now would be a good time to learn about them!

I get goosebumps pretty much daily because I always feel cold. Jeremy don’t get goosebumps for some reason, which I’ve always found a bit strange. (Well, I’ve never seen him get any anyway, not even when he’s cold!)

Apparently goosebumps are triggered by a reflex called piloerection. It causes tiny muscles at the base of each hair to contract, making the little hairs that cover your body to stand up. When animals get cold, this reaction helps fluff up their fur or feathers to lock in warmth, and I suppose it’s meant to do the same for us – except we no longer have fur, just tiny hairs that aren’t going to help us much!

Perhaps back in the day when our ancestors had a lot more hair, it was actually useful! Interesting, huh?

“But why do we get goosebumps when we’re scared?” I hear you ask. Well, this is because when animals get scared, they fluff up their fur to look as big and scary as possible to threaten their attackers. Again, not something we’re able to take advantage of today!

“OK, but what about when we listen to music or just generally feel something nice?” Well, the theory is that when we feel those emotions, our brains release the same chemicals that are released when it’s telling our body we’re cold.

Hopefully you found this just as interesting as I did! Perhaps you already knew about it and I’m just not as up to date with these kind of things as others!

What gives you goosebumps? 🙂
