1 by decreasing muscle activity in the body
2 through peripheral vasodilation in the body
3 through peripheral vasoconstriction in body
4 by shunting blood to superficial body tissues
5 by shunting blood away from the skin surface

3 Through peripheral vasoconstriction in body; 5 By shunting blood away from the skin surface

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
