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.
