Why We Can goosebumps? The following reason

Some of the specific conditions experienced as fear or cold can cause the body's reaction creeps. Why did this phenomenon happen ?

Goosebumps is a physiological phenomenon inherited by our ancestors since time immemorial and experienced by all mammals.
When people feel goose bumps, not just the hair on the skin of the feet but also accompanied by the emergence of the mounds in the hair grows. The emergence of the pile due to the contraction of small muscles.
As quoted from Scientificamerican, chills happen because a person's subconscious mind releases stress hormones called adrenaline. Adrenaline is produced by humans via two small glands above the kidneys not only causes muscle contraction, but also affects many other bodily reactions.

In addition chill can also arise as a result of a small erector muscle contraction that is in the skin. When these stimuli produce neural changes, then there is contraction in the muscles so that the hair above the skin to become established.

Body chills may occur while and disappear a few moments later. And everyone is not able to prevent the body from the goose bumps, as well as with their faces flushed and sweaty bodies.

There are several conditions that can cause body hair on the skin stand, namely :

• Stimulation of cold air.

Based on an article written by Eric Sonstroem from Indiana University in the website 'A Moment of Science', creeps is a primitive reaction arising from the limbic system of the brain. When there is cold air stimulation, then the hair will stand on the tip of her skin to help warm the body.

• emotional reactions

Some emotional reactions can cause the body to shudder, such as fear, watching movies, looking at a work of art or listen to a music concert. Emotions that arise can lead to piloerection of the hair roots to be varied and complex. But until now not known why anyone would shudder to a certain stimuli, while others do not.

• Fight or flight

Creeps into the mechanism of the response of 'fight or light'. When the man felt alert to the presence of a hazard, it will be out adrenaline and blood is pumped into the muscle to be increased so that the body becomes goosebumps.
