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.
When you are too cold your body has several ways to heat itself up, one of these is by shivering. When you shiver you mucsles are working quickly to try and generate heat. Ano â¦ ther way is, when the temperatures are extremely low the blood moves to your body's core, supplying blood to your vital organs. As a reaction to the cold you body curls up/hunches over to try and prevent heat loss. Also, to keep heat loss to a minimum you blood vessels keep away from the top of your skin, this is called vasoconstriction. 17 people found this useful.
