Goosebumps: Often when we see or feel something unexpected, we get goosebumps. In this condition, tingling is felt in the whole body. Goosebumps can happen in any season or at any time, but have you ever thought that why do you get goosebumps? What is the science behind this. If not, then let us know the interesting facts related to Goosebumps…
Why do the hairs stand on end
The process of getting goosebumps is due to piloerection. In such a situation, the hairs of the body stand up on their own for some time, the skin shrinks a bit, a bulge appears near the roots of the hair. Experts say that the piloerector muscles are attached near the hairs, when they contract, the hairs stand up. Piloerection is a voluntary response of the sympathetic nervous system.
getting goosebumps is beneficial or harmful for us
Piloerections cause feelings of cold, fear, or startle. Professor Keith Roach of Cornell University, New York, USA told that goosebumps are beneficial for us. There are not as many hairs in our body as are found in animals or some other mammals. Despite this, the piloerector muscles swell during erection. This is a natural physiological reaction, due to which this sudden reaction has less pressure on other delicate parts of the body and the feeling of cold is less.
Are goosebumps beneficial for animals?
According to Professor Keith Reich, goosebumps are very helpful for animals. Due to muscle contraction during goosebumps, their hair becomes erect. Animals living in cold places have hairy ridges, so air gets filled between their hairs, due to which the feeling of cold is reduced. The second advantage is that in the event of an attack, the animals appear larger than their actual size due to hair growth, due to which other animals get scared.
why do goosebumps come on hearing a sound
According to Professor Keith Roach, getting goosebumps is closely related to sound and a scene. When we watch a movie and see some such scene, which is not expected, then we get goosebumps. He weeps even after listening to a good song. Goosebumps come out even on emotional scenes. Actually, a part of the human brain is responsible for getting goosebumps out of the sound. This is called emotional brain. It gets activated when we hear some unexpected sound. Many times the emotional brain gets activated even on the sound of danger and the hairs stand on end. The brain thinks that this sound is a threat, so goosebumps come out.
