Frigid winds make you shiver; dry air chaps unprotected lips and hands; and a lack of sunshine can even cause depression. Cold weather also puts immense strain on the heart. Low temperatures cause your blood vessels and arteries to narrow, restricting blood flow and reducing oxygen to the heart. Your heart must pump harder to circulate blood through the constricted blood vessels. As a result, your blood pressure increases. A sudden spike in blood pressure â especially when paired with outdoor exertion, such as shoveling a snowy sidewalk â can cause serious issues such as: 1  Unstable chest pain.
Making the world better, one answer at a time. Applying cold therapy to a tissue injury, limits the inflammatory response by causing the blood vessels to constrict (vasoconstriction).This limits the blood flow to the injured site, moderating the release of the vasoactive substances and thus minimizes the pain and swelling in the afflicted area.lood flows slowest in the capillaries since the capillaries have the largest cross-sectional area. Blood flow is inversely related to cross-sectional area.
