Goose Bumps - Cause - Extreme Temperatures

Extreme Temperatures

Goosebumps can be experienced in the presence of cold temperatures. The stimulus of cold surroundings causes the tiny muscles attached to each hair follicle to contract. This contraction causes the hair strands to literally "stand on end." At the same time, the tiny muscles that are contracting are causing a "bunching" of the skin surrounding the hairs, which results in the "bumps" in goosebumps.

This is the body's way of preserving its own heat by causing the hairs on the skin to stand up, thus reducing heat loss. Goosebumps are often seen in conjunction with shivering in these instances.

People also get goosebumps when they are hot, or in the presence of extreme heat. The main reason for this is sweat. As the perspiration accumulates on the skin, it naturally evaporates. As the sweat evaporates, it cools down the skin surface. As this process occurs, a dramatic temperature difference occurs and the body responds to the "chill" of the evaporation of the sweat and the "goosebump response" kicks in.

Famous quotes containing the word extreme:

    When raging love with extreme pain
    Most cruelly distrains my heart,
    When that my tears, as floods of rain,
    Bear witness of my woeful smart;
    When sighs have wasted so my breath
    That I lie at the point of death,
    Henry Howard, Earl Of Surrey (1517?–1547)
