Vasodilation is the widening of blood vessels, which increases blood flow to the skin and helps to release heat from the body, thereby reducing body temperature. This is in contrast to vasoconstriction, shivering, and increased cellular metabolism, which all serve to increase body temperature. A negative feedback loop is a mechanism that can either increase or decrease body temperature depending on the context, but it is not a direct method to increase temperature by itself.
