What is the purpose of goose bumps?

The puckering of the skin that takes place when goose-flesh is formed is the result of contraction of the muscle fibers in the skin. This muscular activity will produce more heat, and raises the temperature of the body.

The thickness of skin varies, depending on where it is found on the body. Skin averages 0.05 inches (0.127 centimeters) in thickness. The thinnest skin is found in the eyelids and is less than 0.002 inches (0.005 centimeters) thick, while the thickest skin is on the upper back (0.2 inches or 0.5 centimeters).
