    Why do humans get “goosebumps”?

    Goosebumps are tiny elevations caused by a contraction of miniature muscles that are attached to hairs. Each contracting muscle creates a shallow depression on the skin surface, which causes the surrounding area to protrude. Getting goosebumps is reflex, which is an action your body has automatically without you even thinking about it. This reflex is known as a pilomotor reflex. Humans aren’t the only mammals that have this reaction.

    While we know what goosebumps are, we don’t know why they have such a strange name. when feathers are pulled from a goose it gives a bumpy flesh behind. Additionally, numerous languages use fowl to describe the bumps.

    Now the question arises that how do humans get “goosebumps”?

    Whenever we are under stress or feels cold or afraid, our brains send signals to our body, all those responses results in the release of a stress hormone called Adrenaline. Adrenaline is a hormone produced by the adrenal gland that participates in the sympathetic system’s “fight or flight responses”. This release is an evolutionary adaption that allows us to better cope with these situations. It results in an increased heartbeat, contradicted blood vessels and goosebumps.
    Other signs of adrenaline release include tears, trembling hands, fast heartbeat or sweaty palms.
