Do you know why Goosebumps come? Why do hairs stand? See there is an Evolutionary reason for this. Each species has a Goal. Everyone has only one Goal which is Survival! The goal of life in the world .. a lot of animals like cats, when it is in danger, means if a wolf comes in front of a cat, then a cute cat starts to look like a demon. This is also the reason for Goosebumps! Nature has created such a system that this cat can look more scary and survive. Cat look scary and dominant by straightening of hairs. This can increase the chances of his survival so that the enemy does not come to him.
It is the same in humans, as you would know that a human was a monkey before. You will know this evolution theory. Many years ago we used to have a lot of hair on our body. As the evolution progressed, this hair became less. But the system of goosebumps still remains. This is why the skin looks slightly raised while having goosebumps, earlier all the hair was erect. When we see horror movies, our body scientist feels that you are in danger. Then adrenaline hormone is released from the andrilin gland on our kidneys and it spreads the adrenaline all over the body and contracts the muscle under the skin. This triggers and causes hair to grow.
Goosebumps mostly comes at the time of fear. This happens when our body feels threatened. Goosebumps come as a result of listening to music, because the music itself makes us feel emotional. Then the body feels like why are there so many unusual emotions awakening in us? That's when he immediately activates the alert Fight and Flight mode.
Goosebumps at the time of cold comes because there was a lot of hair on the body of human beings earlier and when there was a lot of hair, they used to stand at the time of cold. The hair of the body grew and there used to be a Blanket of Warm Air. The body used to get mild heat and the temperature also increased. As we evolve, the hair became less, but the system of Goosebumps in the cold remains even today.

What is the scientific explanation of goosebumps?

Why do we get goosebumps when it's cold?
Each contracting muscle creates a shallow depression on the skin surface, which causes the surrounding area to protrude. The contraction also causes the hair to stand up whenever the body feels cold. In animals with a thick hair coat this rising of hair expands the layer of air that serves as insulation.
Does your hair grow back faster when you get goosebumps?
“Sympathetic nerves next to hair follicles are wrapped around tiny arrector pili muscles, which contract to make hair cells stand on end and cause goosebumps,” says Dr. King. She explains that when this contraction occurs and the hair follicle is stimulated and the hair will grow back at a faster rate.
