As temperatures drop, the risk of health problems - including heart attacks and strokes - goes up.
When we're cold, our blood vessels constrict to prevent heat loss and to keep more blood around the body's core to preserve our vital organs. (That's why fingers and toes get cold.)
But this increases blood pressure, and high blood pressure can lead to a heart attack or stroke, especially in people who already face higher cardiovascular risks. Extreme cold also may cause blood to thicken and become more prone to clotting, which likewise raises the risk of heart attack and stroke.
