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.
Both extreme cold and heat stress the entire body. In order to maintain optimal body temperature, your body has to work extra hard to cool off in the heat, and because your body is using more energy to cool off, your body uses up more oxygen, and so shortness of breath may follow.
