What makes blood vessels constrict?
Normally, the vessels that supply blood to the skin constrict or narrow in response to cold temperatures. This reaction, called "vasoconstriction," decreases blood flow to the skin, which helps to minimize heat loss from the warm blood and therefore preserve a normal internal or "core" temperature.
What opens your blood vessels?
Vasodilators are medications that open (dilate) blood vessels. They affect the muscles in the walls of the arteries and veins, preventing the muscles from tightening and the walls from narrowing. As a result, blood flows more easily through the vessels. The heart doesn't have to pump as hard, reducing blood pressure.
