Question

Increased muscle activity, such as shivering and increased voluntary exercise, is the most effective means of producing heat in response to a cold environmental temperature. Skin vasoconstriction and the formation of "goose bumps" can help to some extent, but they are not as effective as increased muscle activity. Wearing warm clothing and increased food intake can also help to some degree, but they do not directly increase heat production.
