It Can Trigger Cardiovascular Issues. The cold air makes your body work overtime, especially the lungs and heart, because they work in unison to keep that warm blood circulating without skipping a beat. This can cause blood pressure to rise, as blood vessels constrict so they can get back into the heart.
Rising and Sinking Air. Since warm air is less dense and creates less air pressure, it will rise; cold air is denser and creates greater air pressure, and so it will sink. When warm air rises, cooler air will often move in to replace it, so wind often moves from areas where it's colder to areas where it's warmer. The greater the difference between the high and low pressure or the shorter the distance between the high and low pressure areas, the faster the wind will blow.
