    What is vascular constriction?
    Vasoconstriction is the narrowing or even closing of the lumen of a vein, artery, or arteriole as a result of smooth muscle cell constriction in the blood vessel wall. By reducing the diameter of a blood vessel, circulating blood must move through a smaller area under higher pressures. Vasoconstriction is regulated by the autonomic nervous system.

    What is peripheral vasoconstriction?
    Peripheral vasoconstriction occurs when peripheral blood vessels become constricted, most commonly occurring when individuals are exposed to cold. Narrowing peripheral blood vessels constrict blood flow to the periphery (e.g., the skin), preventing the body from losing heat and thereby keeping the body warmer.

    How does vasoconstriction affect your body?
    Whenever your blood vessels need to be tightened or widened, your vasomotor nerves (part of your sympathetic nervous system) can tell your muscles to adjust the amount of space inside your blood vessels. Vasoconstriction can help or hurt your body, depending on the situation.

    What causes vasoconstriction?
    The triggers for vasoconstriction are fluid loss (blood, urine, stomach contents, sweat, fluid evaporation due to severe burns), hypothermia, and hypernatremia (too much sodium in the blood). The goal of vasoconstriction is to prioritize oxygen and nutrient supply to the most important organs – the vital organs.

    What are examples of normal vasoconstriction?
    For example, while exercising, the blood vessels that supply muscles and the lungs dilate, but those that are important for digestion constrict. Vasoconstriction prevents excessive blood loss from wounds or injuries, and helps the body to retain heat in cold environments. These are all situations of normal vasoconstriction.
