Peripheral vasoconstriction is the tightening of the blood vessels, particularly the arteries. It is caused by smoking, drinking alcohol and coffee, as well as the intake of medicine such as antihistamine.
Hypotension is caused by a massive peripheral vasodilation
cold weather causes vasoconstriction. Vasoconstriction restricts blood flow near the skin, so less heat is lost through the skin.

The heart and kidneys
norepinephrine, epinephrine and angiotensin II
Shivering produces heat and vasoconstriction reduces the ability of blood to dump its heat load to the skin's surface where cooling occurs.

Vasoconstriction is the narrowing of blood vessels.
vasoconstriction and vasolidation
Vasoconstriction is the constriction or narrowing of blood vessels by small muscles in their walls, slowing or blocking blood flow. Vasoconstriction is the constriction of blood vessels that increases blood pressure.

Vasoconstriction is the normal narrowing of a blood vessel.
Yes it is. Its principal mechanism of action relies on its indirect action on the adrenergic receptor system. The vasoconstriction that pseudoephedrine produces is believed to be principally an α-adrenergic receptor response.
