Why do you get leg hair stubble when you get gooose bumps?

Question

Just curious. If I shave, then get goose bumps from going outside in the cold weather, I always seem to get stubble on my legs. My friend and I were talking about this and were curious as to why this happens. Can anyone help us out?

So does that mean the hair that is beyond the surface of your skin is forced to the the surface when you get goose bumps?

Also, does anyone have scientific answers?

Answer 1

In mammals, when it is cold the body reacts by "making the hair stand on end" this increases the insulation ability of fir and hair and makes the mammal warmer. We are mammals.

Answer 2

The goose pumps are actually called pilomotor contractions. We get them when we are cold because our hair follicles are trying to make our hairs stand more erect to keep us warm. During the Caveman period people's bodies were more densely covered with hair and it was used to insulate the body and protect it. When the "goosebumps" occured it was to push the hairs up to form a layer of air between the skin and the tips of the hairs to trap the warm air that the body was emitting for warmth. Over the years our body hair has, of course, evolved and does not grow so thick and dense, but the pilomotor contractions have still remained. When we shave and they occur it actually starts pushing the hair further out of the follicle and causes it to begin to grow faster to protect us again....

HERES WHATS REALLY GOING ON
(just learned about it in anatomy)

in your skin there are hair follicles, and attatched to your hair follicles are these tiny little muscles called the arrector pili. when you get cold, the arrector pili causes the hair follicle to contract, or stand up. see, that hair was always there, it was just laying flat.
our hair is almost like feathers on a bird that fluff out when were cold

I HOPE THAT ANSWERS YOUR QUESTION

Answer 4

I am so glad you asked that question, I have wondered it for years, LOL , I hope someone gives you a good answer other than goose bumps make your hair grow......good luck

Answer 5

when your are cold your body tries to get warm. the hair on your legs is there to keep your legs warm. women shave this hair off so when they get cold the body grows the hair longer there to try to protect it from the cold. it is a defense against being cold.
