Quizplus · Accepted Answer

Increased muscle activity, such as shivering and increased voluntary exercise, is the major means of increasing heat production in response to a cold environmental temperature. The contraction of muscles generates heat, which helps to increase body temperature. Skin vasoconstriction and wearing warm clothing can also help to conserve heat, while the formation of "goose bumps" is a physiological response that does not directly increase heat production.
